Medical Doctor

Medical doctor

A physician is a person who practices medicine. See that article for more information on what physicians do in their practices; this article focuses on physician training and regulation. In the United States, the term physician is traditional and commonly used. In Britain, Australia, New Zealand, Japan, South Africa, India, Indonesia, Ireland, Pakistan, Bangladesh, Sri Lanka and Zimbabwe, the term doctor is more common as physician refers to specialists in internal medicine. Because of the extensive training requirements, physicians are traditionally considered to be members of a learned profession.

Training

:See also: medical school and medical residency.

United Kingdom

Medicine in the UK is an undergraduate subject. Students can begin training after leaving the school at 18 years of age. Medical school training lasts either five or six years, depending on the institution, and combines academic and practical training. Junior doctors then enter a vocational training phase. In the UK a doctor's training normally follows this path: #Degree level preclinical - Doctors must study medicine in university or medical school for two to three years "preclinical" (meaning little patient contact). However following recommendations by the British Medical Association (BMA) many universities are following a "Problem-based learning" approach, which stresses basing the studies around actual patient cases. #Clinical - This time is spent in a teaching hospital and typically lasts two or three years. After this is completed the student doctor is awarded a Bachelor of Medicine (BM or MB) and Bachelor of Surgery (BCh or BS). An honorary prefix of "Dr" is now entitled to be used, although it is not recognised in the academic sense of the word (see Doctorate). Doctors who graduated overseas have to pass the Professional and Linguistic Assessment Board test (PLAB) to be eligible for further postgraduate training and jobs in UK. #The Foundation Programme - Due to recent changes in the training of junior doctors, newly qualified doctors enter a two year Foundation Programme, where they train in a variety of different specialities. These must include training in General Medicine and General Surgery but can also include other fields such as Paediatrics or General Practice. Following completion of the Foundation Programme a doctor can choose to specialise in one field. All routes involve further assessment and examinations. The majority in the UK work in the community as General practitioners (GPs), who are the first port of call for patients. They diagnose illness and refer patients for further examination by specialists if necessary. The majority of patients are managed by their GP without the need for further referral. Hospital doctors are promoted after sitting relevant postgraduate exams within their chosen specialty (e.g. Member of the Royal College of Physicians MRCP, Member of the Royal College of Surgeons MRCS) and a competitive interview selection process from SHO to Specialist Registrar and eventually Consultant on completion of the CCST (Certificate of Completion of Specialist Training), which is the highest level in a specialty team (with the exception of university-linked professors). The competition is great for those who wish to attain consultant level and many now complete higher degrees in research such as a Doctorate of Medicine (MD) which is a thesis-based award based on at least two years full-time research or PhD which involves at least three years of full-time research. The time taken to get from graduation from medical school to becoming a Consultant varies from speciality to speciality but can be anything from 7 to 10 years, or longer in some specialities.

United States

In the United States and countries following the U.S. method, the path to a medical degree is somewhat different. #Admissions: Admission into medical school requires either three years of undergraduate study or a four-year post-secondary bachelor's degree from an accredited college or university, depending on medical institution. Most require that the applicant have attained a bachelor's degree prior to matriculation. Admissions criteria include overall performance in the undergraduate years and performance in a group of courses specifically required by U.S. medical schools, the score on the Medical College Admissions Test (a national standardized test), application essays, letters of recommendation (number varies, but at least 1 from science faculty and 1 from non-science faculty), and interview(s). The list of courses required are as follows: #
- biology (1 year) #
- general chemistry (1 year) #
- organic chemistry (1 year) #
- physics (1 year) #
- calculus or sometimes statistics (1 year) #
- English composition (1 year) #
- sometimes behavior science and/or biochemistry (1 semester)
Note:These subjects are studied part time, so several can be completed in one year.

#Medical School: Once admitted to medical school, it takes four years to earn a Doctor of Medicine (M.D.) degree or Doctor of Osteopathic Medicine "Osteopathy" (D.O.) degree. The course of study is divided into two roughly equal parts. Preclinical study generally comprises the first two years and consists of classroom and laboratory instruction in core subjects such as anatomy, biochemistry, physiology, pharmacology, microbiology, pathology, and neurosciences. Once the student successfully completes preclinical training, he or she moves on to the clinical portion. This usually occupies the final two years of medical school and takes place almost exclusively on the wards of a teaching hospital or, occasionally, with community physicians. The students observe and take part in the care of actual patients under the supervision of residents and attending physicians. Rotations on clinical services such as internal medicine, surgery, pediatrics, obstetrics/gynecology, and psychiatry are the foundation of this curriculum, but many specialty electives may be chosen as well. Upon completion of medical school, the student earns the title of doctor, but cannot practice independently until completing further training. Also, several universities across the U.S. admit high school students to both their undergraduate colleges and the medical schools simultaneously; students attend a single six-year to eight-year integrated program consisting of two to four years of an undergraduate curriculum and four years of medical school curriculum, culminating in both a bachelor's and M.D. degree.
#Internship: During the last year of medical school, students apply for postgraduate residencies in their chosen field of specialization. These are more or less competitive depending upon the desirability of the specialty, prestige of the program, and the number of applicants relative to the number of available positions. All but a few positions are granted via a national computer match which pairs an applicant's preference with the programs' preference for applicants. The first year of any residency is known as "internship". Completion of this year is the minimum training requirement for obtaining a license to practice medicine in the U.S.
#Residency: Each of the specialties in medicine has established its own curriculum, which defines the length and content of residency training necessary to practice in that specialty. Programs range from three years after medical school for internal medicine to five years for surgery to eight or nine for neurosurgery. This does not include research years that may last from 1 year up to a completion of a Ph.D. Each specialty incorporates an internship year to satisfy the requirements of licensure. All specialties hold a board exam (either written or written and oral) at the completion of training in order to confer "Board Certification" in that specialty.
#Fellowship: Certain highly specialized fields require formal training beyond residency. Examples of these are cardiology, endocrinology, oncology after internal medicine; cardiothoracic surgery, pediatric surgery, surgical oncology after general surgery to name just a few. There are many others for each field of study. The training programs for these fields are known as fellowships and their participants are "Fellows" to denote that they already have completed a residency and are "Board Eligible" or "Board Certified" in their basic specialty. Fellowships range in length from one to three years and are granted by application to the individual program or sub-specialty organizing board.
#Attending physicians and Consultants: The physician or surgeon who has completed his or her residency and possibly fellowship training and is in the practice of their specialty is known as an Attending or Consultant. These are the physicians who may independently care for patients and are the final arbiters of care. They are responsible for all care decisions and may bill for their services. However, medicine is an extremely diverse profession with many options available. Some doctors work in pharmaceutical research, occupational medicine (within a company), public health medicine (working for the general health of a population in an area), or join the armed forces.

France

In France, a doctor's training is performed in public university hospital, called Centre hospitalier universitaire or CHU; it consists in:
- First cycle
- the first year is common with the dentists and the midwives; the rank at the final examination determines in which branch the student can go on; it is called "PCEM1" (premier cycle des études médicales, first cycle of medical studies) or "P1";
- the second year is called "PCEM2" and is dedicated to the fundamental sciences (or propédeutique, propaedeutics): anatomy, human physiology, biochemistry, bacteriology, statistics...
- Second cycle
- The first year is called "DCEM1" (deuxième cycle des études médicales, second cycle of medical studies), and is also dedicated to the study of propaedeutics
- The second, third and fourth years (DCEM2-4) are called externat, and are dedicated to the study of clinical medicine; they end with a classifying examination, the rank determines in which speciality (the general medicine is one of them) the student can make an internat: the first graduate can choose speciality, and at the rank n, the graduate must choose amongst the places left; the graduate also gets a Certificat de synthèse clinique et thérapeutique (certificate of clinical and therapeutical synthesis).
- The internat is two years and a half (general medicine) or four years (specialist) of initial professional experience under the responsibility of a senior; the interne can prescribe, replacements of liberal phsicians can be made, and usually the student works in an hospital. This ends with a doctorate, a research work which most of times consist in a statistical study of cases to propose a care strategy of a specific affection (in an epidemiological, diagnostical, or therapeutical point of view). A specialist also gets a DES (diplôme d'études spécialisées, diploma for specialised studies). The initial training thus consist in eight years and a half for a general practitioner, and ten years for a specialist (including a surgeon).

Regulation

In most jurisdictions, physicians need government permission to practise. This is known as licensing in the United States, as colegiation in Spain, as ishi menkyo in Japan, as autorisasjon in Norway, as approbation in Germany, and as registration in Australia and the United Kingdom. In France, civilian physicians must be a member of the Order of physicians to practice medicine. In some countries, including the United Kingdom, the profession regulates itself, with the government affirming the regulating body's authority (in the UK the General Medical Council [GMC]). Regulating authorities will revoke permission to practice in cases of malpractice or serious misconduct. Graduates of Foreign Medical Schools, who enter USA have to pass USMLE step 1 and 2 [http://ecfmg.org/ ECFMG old name]and do a residency program to qualify for a state license. After graduating from medical school, American physicians usually take a standardized exam which enables them to obtain a certificate to practice from the appropriate state agency. All American states have an agency which is usually called the "Medical Board," although there are alternate names such as "Board of Medicine," "Board of Medical Examiners," "Board of Medical Licensure," "Board of Healing Arts," etc. Australian states usually have a "Medical Board," while Canadian provinces usually have a "College of Physicians and Surgeons." In the United States, as a result of the war on drugs, pharmaceuticals are strictly regulated at the federal level by the Food and Drug Administration and the Drug Enforcement Administration. All practicing American physicians who intend to prescribe controlled substances must obtain a number from the DEA, and that DEA number must appear on all their prescriptions. Use of the DEA number enables dispensing pharmacists or the DEA to ensure that a physician is not dispensing potentially addictive or harmful drugs, such as opiates or stimulants, in contravention to accepted standards of care.

United States

:For alternative meanings, see the disambiguation page for US, USA, United States, or American. The United States of America is a federal democratic republic situated primarily in central North America. It comprises 50 states and one federal district, and has several territories. It is also referred to, with varying formality, as the United States, the U.S., the U.S.A., the States, or simply and most commonly, America. The official founding date of the United States is July 4, 1776, when the Second Continental Congress—representing thirteen British colonies—adopted the Declaration of Independence. However, the structure of the government was profoundly changed in 1788, when the states replaced the Articles of Confederation with the United States Constitution. The date on which each of the fifty states adopted the Constitution is typically regarded as the date that state "entered the Union" (became part of the United States). Since the mid-20th century, following World War II, the United States has emerged as a dominant global influence in economic, political, military, scientific, technological, and cultural affairs.

Geography and climate

The United States shares land borders with Canada (to the north) and Mexico (to the south), and territorial water boundaries with Canada, Russia, the Bahamas, and numerous smaller nations. It is otherwise bounded by the Pacific Ocean and the Bering Sea, in the west; the Arctic Ocean, in the northernmost areas; and the Atlantic Ocean, the Gulf of Mexico, and the Caribbean Sea, in the eastern and southeastern areas. Forty-eight of the states are in the single region between Canada and Mexico; this group is referred to, with varying precision and formality, as the continental or contiguous United States, sometimes abbreviated CONUS, and as the Lower 48. Alaska, which is not included in the term contiguous United States, is at the northwestern end of North America, separated from the Lower 48 by Canada. The archipelago of Hawaii is in the Pacific Ocean. The capital city, Washington, District of Columbia is a federal district located on land donated by the state of Maryland. (Virginia also donated land, but it was returned in 1847.) The United States also has overseas territories with varying levels of independence and organization. When inland water is included in the total area, only Russia and Canada are larger than the United States; if inland water is excluded, China ranks third and the U.S. ranks fourth. The United States' total area is 3,718,711 square miles (9,631,418 km²), of which land makes up 3,537,438 square miles (9,161,923 km²) and water makes up 181,273 square miles (469,495 km²). The United States' landscape is one of the most varied among those of the world's nations: among its many features are temperate forestland and rolling hills, on the east coast; mangrove, in Florida; the Great Plains, in the center of the country; the Mississippi–Missouri river system; the Great Lakes, four of the five of which are shared with Canada; the Rocky Mountains, west of the Great Plains; deserts and temperate coastal zones, west of the Rocky Mountains; and temperate rain forests, in the Pacific northwest. Alaska's tundra, and the volcanic, tropical islands of Hawaii add to the geographic diversity. Hawaii The climate varies along with the landscape, from tropical in Hawaii and southern Florida to tundra in Alaska and atop some of the highest mountains. Most of the North and East experience a temperate continental climate, with warm summers and cold winters. Most of the South experiences a subtropical humid climate with mild winters and long, hot, humid summers. Rainfall decreases markedly from the humid forests of the Eastern Great Plains to the semi-arid shortgrass prairies on the high plains abutting the Rocky Mountains. Arid deserts, including the Mojave, extend through the lowlands and valleys of the southwest, from westernmost Texas to California and northward throughout much of Nevada. Some parts of California have a Mediterranean climate. Rainforests line the windward mountains of the Pacific Northwest from Oregon to Alaska.

History

American history started with the migration of people from Asia across the Bering land bridge approximately 12,000 years ago following large animals that they hunted into the Americas. These Native Americans left evidence of their presence in petroglyphs, burial mounds, and other artifacts. It is estimated that 2-9 million people lived in the territory now occupied by the U.S. before European contact, and the subsequent introduction of foreign diseases such as small pox that greatly diminished the native populations. Some advanced societies were the Anasazi of the southwest, who inhabited Chaco Canyon, and the Woodland Indians, who built Cahokia, located near present-day St Louis, a city with a population of 40,000 at its peak in AD 1200. Vikings first visited North America around 1000, but did not settle permanently. Following the discovery voyages of Christopher Columbus around 1492, other Europeans began to explore and settle there. During the 1500s and 1600s, the Spanish settled parts of the present-day Southwest and Florida, founding St. Augustine, Florida in 1565 and Santa Fe (in what is now New Mexico) in 1607. The first successful English settlement was at Jamestown, Virginia, also in 1607. Within the next two decades, several Dutch settlements, including New Amsterdam (the predecessor to New York City), were established in what are now the states of New York and New Jersey. In 1637, Sweden established a colony at Fort Christina (in what is now Delaware), but lost the settlement to the Dutch in 1655. This was followed by extensive British settlement of the east coast. The British colonists remained relatively undisturbed by their home country until after the French and Indian War, when France ceded Canada and the Great Lakes region to Britain. Britain then imposed taxes on the 13 colonies, widely regarded by the colonists as unfair because they were denied representation in the British Parliament. Tensions between Britain and the colonists increased, and the thirteen colonies eventually rebelled against British rule. British Parliament, George Washington (1789-1797).]] In 1776, the 13 colonies split from Great Britain and formed the United States, the world's first constitutional and democratic federal republic, after their Declaration of Independence of that year, and the Revolutionary War (1775 to 1783). The original political structure was a confederation in 1777, ratified in 1781 as the Articles of Confederation. After long debate, this was supplanted by the Constitution in 1789, forming a more centralized federal government. Prior to all these was the Albany Congress in 1754, in which a union was first seriously proposed. From early colonial times, there was a shortage of labor, which encouraged unfree labor, particularly indentured servitude and slavery. In the mid-19th century, a major division occurred in the United States over the issue of states' rights and the expansion of slavery. The northern states had become opposed to slavery, while the southern states saw it as necessary for the continued success of southern agriculture and wanted it expanded to the territories. Several federal laws were passed in an attempt to settle the dispute, including the Missouri Compromise and the Compromise of 1850. The dispute reached a crisis in 1861, when seven southern states seceded¹ from the Union and formed the Confederate States of America, leading to the Civil War. Soon after the war began, four more southern states seceded. During the war, Abraham Lincoln issued the Emancipation Proclamation, mandating the freedom of all slaves in states in rebellion, though full emancipation did not take place until after the end of the war in 1865, the dissolution of the Confederacy, and the Thirteenth Amendment took effect. The Civil War effectively ended the question of a state's right to secede, and is widely accepted as a major turning point after which the federal government became more powerful than state governments. Thirteenth Amendment). The title of the painting, from a 1726 poem by Bishop Berkeley, was a phrase often quoted in the era of Manifest Destiny, expressing a widely held belief that civilization had steadily moved westward throughout history. [http://americanart.si.edu/t2go/1lw/1931.6.1.html (more)] ]] During the 19th century, many new states were added to the original 13 as the nation expanded across the continent. Manifest Destiny was a philosophy that encouraged westward expansion in the United States. As the population of the Eastern states grew and as a steady increase of immigrants entered the country, settlers moved steadily westward across North America. In the process, the U.S. displaced most American Indian nations. This displacement of American Indians continues to be a matter of contention in the U.S. with many tribes attempting to assert their original claims to various lands. In some areas American Indian populations were reduced by foreign diseases contracted through contact with European settlers, and US settlers acquired those emptied lands. In other instances American Indians were removed from their traditional lands by force. Though some would say the U.S. was not a colonial power until the Spanish-American War when it acquired Puerto Rico, Guam and the Philippines, the dominion exercised over land in North America the United States claimed is essentially colonial. The Philippines became independent in 1946. During this period, the nation also became an industrial power. This continued into the 20th century, which has been termed "the American Century" because of the nation's overriding influence on the world. The US became a center for innovation and technological development; major technologies that America either developed or was greatly involved in improving include the telephone, television, computer, the Internet, nuclear weapons, nuclear power, aviation, and aeronautics. In addition to the Civil War, another major traumatic experience for the nation was the Great Depression (1929 to 1939). The nation has also taken part in several major foreign wars, including World War I and World War II (in both of which the US later joined the Allies). During the Cold War, the US was a major player in the Korean War and Vietnam War, and, along with the Soviet Union, was considered one of the world's two "superpowers". With the collapse of the Soviet Union, the US emerged as the world's leading economic and military power. Beginning in the 1990s, the United States became very involved in police actions and peacekeeping, including actions in Kosovo, Haiti, Somalia and Liberia, and the first Persian Gulf War driving Iraq out of Kuwait. After attacks on the World Trade Center and the Pentagon on September 11, 2001, the United States and other allied nations found themselves involved in what has come to be called the "War on Terrorism," which has primarily encompassed military actions in both Afghanistan and Iraq.

Government

Iraq of the United States.]]

Republic and suffrage

The United States is an example of a constitutional republic, with a government composed of and operating through a set of limited powers imposed by its design and enumerated in the United States Constitution. Specifically, the nation operates as a presidential democracy. There are three levels of government: federal, state, and local. Officials of each of these levels are either elected by eligible voters via secret ballot or appointed by other elected officials. Americans enjoy almost universal suffrage from the age of 18 regardless of race, sex, or wealth. There are some limits, however: felons are disenfranchised and in some states former felons are likewise. Furthermore, the national representation of territories and the federal district of Washington, DC in Congress is limited: residents of the District of Columbia are subject to federal laws and federal taxes but their only Congressional representative is a non-voting delegate.

Federal government

The federal government is the national government, comprising the Legislative Branch (led by Congress), the Executive Branch (led by the President), and the Judicial Branch (led by the Supreme Court). These three branches were designed to apply checks and balances on each other. The Constitution limits the powers of the federal government to defense, foreign affairs, the issuing and management of currency, the management of trade and relations between the states, and the protection of human rights. In addition to these explicitly stated powers, the federal government—with the assistance of the Supreme Court—has gradually extended these powers into such areas as welfare and education, on the basis of the "necessary and proper" clause of the Constitution.

The Congress

necessary and proper The Congress of the United States is the legislative branch of the federal government of the United States. It is bicameral, comprising the House of Representatives and the Senate. The House of Representatives consists of 435 members, each of whom represents a congressional district and serves for a two-year term. House seats are apportioned among the states by population; in contrast, each state has two Senators, regardless of population. There are a total of 100 senators, who serve six-year terms. The powers of Congress are limited to those enumerated in the Constitution; all other powers are reserved to the states and the people. The Constitution also includes the necessary-and-proper clause, which grants Congress the power to "make all laws which shall be necessary and proper for carrying into execution the foregoing powers."

The President

necessary-and-proper clause At the top level of the executive branch is the President of the United States. The President and Vice-President are elected as 'running mates' for four-year terms by the Electoral College, for which each state, as well as the District of Columbia, is allocated a number of seats based on its representation (or ostensible representation, in the case of D. C.) in both houses of Congress (see U.S. Electoral College). The relationship between the President and the Congress reflects that between the English monarchy and parliament at the time of the framing of the United States Constitution. Congress can legislate to constrain the President's executive power, even with respect to his or her command of the armed forces; however, this power is used only very rarely—a notable example was the constraint placed on President Richard Nixon's strategy of bombing Cambodia during the Vietnam War. The President cannot directly propose legislation, and must rely on supporters in Congress to promote his or her legislative agenda. The President's signature is required to turn congressional bills into law; in this respect, the President has the power—only occasionally used—to veto congressional legislation. Congress can override a presidential veto with a two-thirds majority vote in both houses. The ultimate power of Congress over the President is that of impeachment or removal of the elected President through a House vote, a Senate trial, and a Senate vote. The threat of using this power has had major political ramifications in the cases of Presidents Andrew Johnson, Richard Nixon, and Bill Clinton. The President makes around 2,000 executive appointments, including members of the Cabinet and ambassadors, which must be approved by the Senate; the President can also issue executive orders and pardons, and has other Constitutional duties, among them the requirement to give a State of the Union address to Congress once a year. Although the President's constitutional role may appear to be constrained, in practice, the office carries enormous prestige that typically eclipses the power of Congress: the Presidency has justifiably been referred to as 'the most powerful office in the world'. The Vice President is first in the line of succession, and is the President of the Senate ex officio, with the ability to cast a tie-breaking vote. The members of the President's Cabinet are responsible for administering the various departments of state, including the Department of Defense, the Justice Department, and the State Department. These departments and department heads have considerable regulatory and political power, and it is they who are responsible for executing federal laws and regulations. George W. Bush is the 43rd President, currently serving his second term.

The Courts

George W. Bush The highest court is the Supreme Court, which consists of nine justices. The court deals with federal and constitutional matters, and can declare legislation made at any level of the government as unconstitutional, nullifying the law and creating precedent for future law and decisions. Below the Supreme Court are the courts of appeals, and below them in turn are the district courts, which are the general trial courts for federal law. Separate from, but not entirely independent of, this federal court system are the individual court systems of each state, each dealing with its own laws and having its own judicial rules and procedures. A case may be appealed from a state court to a federal court only if there is a federal question; the supreme court of each state is the final authority on the interpretation of that state's laws and constitution.

State and local governments

supreme court of each state. Note that Alaska and Hawaii are shown at different scales, and that the Aleutian Islands and the uninhabited Northwestern Hawaiian Islands are omitted from this map.]] The state governments have the greatest influence over people's daily lives. Each state has its own written constitution and has different laws. There are sometimes great differences in law and procedure between the different states, concerning issues such as property, crime, health, and education. The highest elected official of each state is the Governor. Each state also has an elected legislature (bicameral in every state except Nebraska), whose members represent the different parts of the state. Of note is the New Hampshire legislature, which is the third-largest legislative body in the English-speaking world, and has one representative for every 3,000 people. Each state maintains its own judiciary, with the lowest level typically being county courts, and culminating in each state supreme court, though sometimes named differently. In some states, supreme and lower court justices are elected by the people; in others, they are appointed, as they are in the federal system. The institutions that are responsible for local government are typically town, city, or county boards, making laws that affect their particular area. These laws concern issues such as traffic, the sale of alcohol, and keeping animals. The highest elected official of a town or city is usually the mayor. In New England, towns operate directly democratically, and in some states, such as Rhode Island and Connecticut, counties have little or no power, existing only as geographic distinctions. In other areas, county governments have more power, such as to collect taxes and maintain law enforcement agencies.

Political divisions

With the Declaration of Independence, the thirteen colonies proclaimed themselves to be nation states modeled after the European states of the time. Although considered as sovereigns initially, under the Articles of Confederation of 1781 they entered into a "Perpetual Union" and created a fully sovereign federal state, delegating certain powers to the national Congress, including the right to engage in diplomatic relations and to levy war, while each retaining their individual sovereignty, freedom and independence. But the national government proved too ineffective, so the administrative structure of the government was vastly reorganized with the United States Constitution of 1789. Under this new union, the continued status of the individual states as sovereign nation states fell into dispute in 1861, as several states attempted to secede from the union; in response, then-President Abraham Lincoln claimed that such secession was illegal, and the result was the American Civil War. Since the Union victory in 1865, the independent status of the individual states has not been broached again by any state, and the status of each state within the union has been deemed by mainstream officials and academics to be settled as being subordinate to the union as a whole. In subsequent years, the number of states grew steadily due to western expansion, the purchase of lands by the national government from other nation states, and the subdivision of existing states, resulting in the current total of 50. The states are generally divided into smaller administrative regions, including counties, cities and townships. The United States–Canadian border is the longest undefended political boundary in the world. The U.S. is divided into three distinct sections:
- the "continental United States," also known as "the Lower 48" and more accurately termed the conterminous, coterminous or contiguous United States
- Alaska, which is physically connected only to Canada
- the archipelago of Hawaii, in the central Pacific Ocean. The United States also holds several other territories, districts, and possessions, notably the federal district of the District of Columbia, which is the nation's capital, and several overseas insular areas, the most significant of which are American Samoa, Guam, the Northern Mariana Islands, Puerto Rico, and the United States Virgin Islands. The Palmyra Atoll is the United States' only incorporated territory; it is unorganized and uninhabited. The United States Navy has held a base at a portion of Guantanamo Bay, Cuba, since 1898. The United States government possesses a lease to this land, which only mutual agreement or United States abandonment of the area can terminate. The present Cuban government of Fidel Castro disputes this arrangement, claiming Cuba was not truly sovereign at the time of the signing. The United States argues this point moot because Cuba apparently ratified the lease post-revolution, and with full sovereignty, when it cashed one rent check in accordance with the disputed treaty.

Foreign relations and military

sovereign] The immense military and economic dominance of the United States has made foreign relations an especially important topic in its politics, with considerable concern about the image of the United States throughout the world. Reactions towards the United States by other nationalities are often strong, ranging from uninhibited admiration and mimicking of all things American to anti-Americanism. US foreign policy has swung about several times over the course of its history between the poles of strict isolationism and imperialism and everywhere in between. Three of the nation's four military branches are administered by the Department of Defense: the Army, the Navy (including the Marine Corps), and the Air Force. The Coast Guard falls under the jurisdiction of the Department of Homeland Security in peacetime, but is placed under the Department of the Navy in time of war. The combined United States armed forces consist of 1.4 million active duty personnel, along with several hundred thousand each in the Reserves and the National Guard. Military conscription ended in 1973. The United States Armed forces are considered to be the most powerful military (of any sort) on Earth and their force projection capabilities are unrivaled by any other nation. The 2005 defense budget amounted to $401.7 billion, which is an increase of 4% over 2004 and of 35% since 2001. Over 50% of that number is spent in research & development. (For comparison, in 2004 the European Union (considered as the second-largest military force) had a combined total of 1.6 million troops, and a defense budget of €160 billion, with less than 10% of that being spent on R&D.)

Largest cities

The United States has dozens of major cities, including 11 of the 55 global cities of all types — with three "alpha" global cities: New York City, Los Angeles, and Chicago. The figures expressed below are for populations within city limits. A different ranking is evident when considering U.S. metro area populations, although the top three would be unchanged. Note that some cities not listed (such as Atlanta, Boston, Las Vegas, Miami, Nashville, New Orleans, Seattle, and Washington, D.C.) are still considered important on the basis of other factors and issues, including culture, economics, heritage, and politics. The twenty largest cities, based on the United States Census Bureau's 2004 estimates, are as follows:

Economy

The United States has the largest single-country economy in the world, with a per-capita gross domestic product of $40,100. In this market-oriented economy, private individuals and business firms make most of the decisions, and the federal and state governments buy needed goods and services predominantly in the private marketplace. gross domestic product The largest industry of the U.S. is now service, which employs roughly three quarters of the U.S. work force. The United States has many natural resources, including oil and gas, metals, and such minerals as gold, soda ash, and zinc. In agriculture, the U.S. is a top producer of, among other crops, corn, soy beans, and wheat; the United States is a net exporter of food. The U.S. manufacturing sector produces goods such as, cars, airplanes, steel, and electronics, among many others. Economic activity varies greatly from one part of the country to another, with many industries being largely dependent on a certain city or region; New York City is the center of the American financial, publishing, broadcasting, and advertising industries; Silicon Valley is the country’s primary location for high-technology companies, while Los Angeles is the most important center for film production. The Midwest is known for its reliance on manufacturing and heavy industry, with Detroit, Michigan, serving as the center of the American automotive industry; the Great Plains are known as the "breadbasket" of America for their tremendous agricultural output; the intermountain region serves as a mining hub and natural gas resource; the Pacific Northwest for fish and timber, while Texas is largely associated with the oil industry; the Southeast is a major hub for both medical research and the textiles industry. Several countries continue to link their currency to the dollar or even use it as a currency (such as Ecuador), although this practice has subsided since the collapse of the Bretton Woods system. Many markets are also quoted in dollars, such as those of oil and gold. The dollar is also the predominant reserve currency in the world, and more than half of global reserves are in dollars. The largest trading partner of the United States is Canada (19%), followed by China (12%), Mexico (11%), and Japan (8%). More than 50% of total trade is with these four countries. In 2003, the United States was ranked as the third most visited tourist destination in the world; its 40,400,000 visitors ranked behind France's 75,000,000 and Spain's 52,500,000. Labor unions have existed since the 19th century, and grew large and powerful from the 1930s to the 1950s. See Labor history of the United States. Since 1970 they have shrunk in the private sector and now cover fewer than 8% of the workers. However union membership has grown rapidly in the public sector, especially among teachers, nurses, police, postal workers, and municipal clerks. There have been few strikes in recent years. The United States' imports exceed exports by 80%, leading to an annual trade deficit of $700,000,000,000, or 6% of gross domestic product. It is the largest debtor nation in the world, with total gross foreign debt of over $13,000,000,000,000 (2005 estimate); and it absorbs more than 50% of global savings annually. Since the 1980s, the U.S. has increased the use of neoliberal economic policies that reduce government intervention and reduce the size of the welfare state, backing away from the more interventionist Keynsian economic policies that had been in favor since the Great Depression. As a result, the United States provides fewer government-delivered social welfare services than most industrialized nations, choosing instead to keep its tax burden lower and relying more heavily on the free market and private charities. Sixteen states and the District of Columbia have minimum wages higher than the national level ($5.15 per-hour), including the highest, Washington State at $7.35. Twenty-six states are the same as the federal level; two--Ohio and Kansas--are below; and six do not have state laws. America's wealth is relatively highly concentrated. The average C.E.O. earns 500 times the typical amount a worker grosses, this is up from 25 times in the late 1970s. In terms of wealth the top 1% of Americans own 40% of all assets and 50.1% of the country's income goes to the top twenty percent of households. Average wages for the majority of employees have been largely stagnating since the 1970s. America's poverty line defined as a family of four earning less than $19,157 is at 12.7% of the general population. Approximately one out of every five children in the United States grows up below the official poverty line. Among racial groups; African Americans have the lowest median income while Asians had the highest. Regionally, the southern states had the lowest median incomes while the West Coast and New England had the highest. The current Federal Reserve Chairman Alan Greenspan remarked that the U.S.’s growing income inequality since the 1970s is, "not the type of thing which a democratic society - a capitalist democratic society - can really accept without addressing."[http://www.csmonitor.com/2005/0614/p01s03-usec.html?s=itm] However, Greenspan also noted, "...you can look at the system and say it's got a lot of problems to it, and sure it does. It always has. But you can't get around the fact that this is the most extraordinarily successful economy in history."

Transportation

Alan Greenspan ]] Because the United States is a relatively young nation, most of the development of U.S. cities has taken place since the invention of the automobile. To link its vast territory, the United States built a network of high-capacity, high-speed highways, of which the most important element is the Interstate Highway system, commissioned in the 1950s by President Dwight D. Eisenhower and modeled after the German Autobahn. The United States also has a transcontinental rail system, which is used for moving freight across the lower forty-eight states. Passenger rail service is provided by Amtrak, which serves forty-six of the lower forty-eight states. Many cities in the United States have extensive mass-transit systems. New York City operates one of the world's largest and most heavily used subway systems. The regional rail and bus networks that extend into Long Island, New Jersey, Upstate New York, and Connecticut are among the most heavily used in the world. Air travel is often preferred for destinations over 300 miles (500 kilometers) away. In terms of passengers, seventeen of the world's thirty busiest airports in 2004 were in the U.S., including the world's busiest, Hartsfield-Jackson Atlanta International Airport; in terms of cargo, in the same year, twelve of the world's thirty busiest airports were in the U.S., including the world's busiest, Memphis International Airport. There are several major seaports in the United States; the three busiest are the Port of Los Angeles, California; the Port of Long Beach, California; and the Port of New York and New Jersey. Others include Houston, Texas; Charleston, South Carolina; Savannah, Georgia; Miami, Florida; Portland, Oregon; San Francisco, California; Boston, Massachusetts; Philadelphia, Pennsylvania; and Seattle, Washington; plus, outside the contiguous forty-eight states, Anchorage, Alaska, and Honolulu, Hawaii.

Ethnicity and race

:Main article: Racial demographics of the United States The United States is a very racially diverse country. According to the 2000 census, it has 31 ethnic groups with at least one million members each, and numerous others represented in smaller amounts. The majority of Americans descend from white European immigrants who arrived at the establishment of the first colonies (most after Reconstruction). This majority--69.1% in 2000--decreases each year, and is expected to become a plurality within a few decades. The most frequently stated European ancestries are German (15.2%), Irish (10.8%), English (8.7%), Italian (5.6%) and Scandinavian (3.7%). Many immigrants also hail from Slavic countries such as Poland and Russia. Other significant immigrant populations came from eastern and southern Europe and French Canada. Russia Hispanics from Mexico and South and Central America are the largest minority group in the country, comprising 12.5% of the population (2000 census). People of Mexican descent made up 7.3% of the population in the 2000 census, and this proportion is expected to increase significantly in the coming decades. About 12.3% (2000 census) of the American people are African Americans (Blacks). African Americans are spread throughout the country, but their presence is largest in the South. Asian Americans--including Native Hawaiians and Pacific Islanders--are a third significant minority (3.7% of the population in 2000). Most Asian Americans are concentrated on the West Coast and Hawaii. The largest groups are immigrants or descendants of emigrants from the Philippines, China, India, Vietnam, South Korea, and Japan. Indigenous peoples in the United States, such as American Indians and Inuit, make up 0.9% of the population (2000 census). About 35% live on Indian reservations.

Religion

Polls estimate that just under 80 percent of Americans are Christians of various denominations. The other 20 percent comprises other religions such as Hinduism, Judaism, Islam, and Buddhism, other various faiths, and those without a specific religion. The United States is noteworthy among developed nations for its relatively high level of religiosity. According to a 2004 Gallup poll, about 44% of Americans attend a religious service at least once a week. However, this rate is not uniform across the country; attendance is more common in the Bible Belt—composed largely of Southern and Midwestern states—than in the Northeast and West Coast. In the Southern states, Baptists are the largest group, followed by Methodists; Roman Catholics are dominant in the Northeast and in large parts of the Midwest due to their being settled by descendants of Catholic immigrants from Europe (such as Germany, Ireland, Italy, and Poland) or other parts of North America (mainly Quebec and Puerto Rico). The rest of the country for the most part has a complex mixture of various Christian groups.

Education

West Coast's home at Monticello and the University of Virginia (library building shown above, and designed by Jefferson), the only collegiate campus on the list. Both sites are located in Charlottesville, Virginia.]] In the United States, education is a state, not federal, responsibility, and the laws and standards vary considerably. However, the federal government, through the Department of Education, is involved with funding of some programs and exerts some influence through its ability to control funding. In most states, all students must attend mandatory schooling starting with kindergarten, which children normally enter at age 5, and following through 12th grade, which is normally completed at age 18

Australia

The Commonwealth of Australia is a country in the Southern Hemisphere comprising the world's smallest continent and a number of islands in the Southern, Indian and Pacific Oceans. Australia's neighbouring countries are Indonesia, East Timor and Papua New Guinea to the north, the Solomon Islands, Vanuatu and New Caledonia to the northeast, and New Zealand to the southeast. The continent of Australia has been inhabited for over 40,000 years by Indigenous Australians. After sporadic visits by fishermen from the north and by European explorers and merchants starting in the 17th century, the eastern half of the continent was claimed by the British in 1770 and officially settled as the penal colony of New South Wales on 26 January 1788. As the population grew and new areas were explored, another five largely self-governing Crown Colonies were successively established over the course of the 19th century. On 1 January 1901, the six colonies federated and the Commonwealth of Australia was formed. Since federation, Australia has maintained a stable liberal democratic political system and remains a Commonwealth Realm. The current population of around 20.4 million is concentrated mainly in the large coastal cities of Sydney, Melbourne, Brisbane, Perth and Adelaide.

Origin and history of the name

The name Australia is derived from the Latin australis, meaning southern. Legends of an "unknown southern land" (terra australis incognita) date back to the Roman times and were commonplace in mediæval geography, but they were not based on any actual knowledge of the continent. The Dutch adjectival form Australische ("Australian," in the sense of "southern") was used by Dutch officials in Batavia to refer to the newly discovered land to the south as early as 1638. The first English language writer to use the word "Australia" was Alexander Dalrymple in An Historical Collection of Voyages and Discoveries in the South Pacific Ocean, published in 1771. He used the term to refer to the entire South Pacific region, not specifically to the Australian continent. In 1793, George Shaw and Sir James Smith published Zoology and Botany of New Holland, in which they wrote of "the vast island, or rather continent, of Australia, Australasia or New Holland." New Holland was established on this site.]] The name "Australia" was popularised by the 1814 work A Voyage to Terra Australis by the navigator Matthew Flinders. Despite its title, which reflected the view of the Admiralty, Flinders used the word "Australia" in the book, which was widely read and gave the term general currency. Governor Lachlan Macquarie of New South Wales subsequently used the word in his dispatches to England. In 1817 he recommended that it be officially adopted. In 1824, the British Admiralty agreed that the continent should be known officially as Australia.

History

England, claiming the land for Britain in 1770. This replica was built in Fremantle in 1988 for Australia's bicentenary.]] The first human habitation of Australia is estimated to have occurred between 42,000 and 48,000 years ago. The first Australians were the ancestors of the current Indigenous Australians; they arrived via land bridges and short sea-crossings from present-day India or Southeast Asia. Most of these people were hunter-gatherers, with a complex oral culture and spiritual values based on reverence for the land and a belief in the Dreamtime. The Torres Strait Islanders, ethnically Melanesian, inhabited the Torres Strait Islands and parts of far-north Queensland; they possess distinct cultural practices and practised subsistence agriculture. The first undisputed recorded European sighting of the Australian continent was made by the Dutch navigator Willem Jansz, who sighted the coast of Cape York Peninsula in 1606. During the 17th century, the Dutch charted the whole of the western and northern coastlines of what they called New Holland, but made no attempt at settlement. In 1770, James Cook sailed along and mapped the east coast of Australia, which he named New South Wales and claimed for Britain. The expedition's discoveries provided impetus for the establishment of a penal colony there following the loss of the American colonies that had previously filled that role. penal colony was Australia's largest penal colony.]] The British Crown Colony of New South Wales started with the establishment of a settlement at Port Jackson by Captain Arthur Phillip on 26 January 1788. This date was later to become Australia's national day, Australia Day. Van Diemen's Land, now known as Tasmania, was settled in 1803 and became a separate colony in 1825. Britain formally claimed the western part of Australia in 1829. Separate colonies were created from parts of New South Wales: South Australia in 1836, Victoria in 1851, and Queensland in 1859. The Northern Territory (NT) was founded in 1863 as part of the Province of South Australia. Victoria and South Australia were founded as "free colonies"—that is, they were never penal colonies, although the former did receive some convicts from Tasmania. Western Australia was also founded "free", but later accepted transported convicts due to an acute labour shortage. The transportation of convicts to Australia was phased out between 1840 and 1868. The Indigenous Australian population, estimated at about 350,000 at the time of European settlement, declined steeply for 150 years following settlement, mainly because of infectious disease, and forced migration, the removal of children and other colonial government policies, that some historians and Indigenous Australians have argued could be considered to constitute genocide by today's understanding. Such interpretations of Aboriginal history are disputed by some as being exaggerated or fabricated for political or ideological reasons. Following the 1967 referendum, the Federal government gained the power to implement policies and make laws with respect to Aborigines. Traditional ownership of land—native title—was not recognised until the High Court case Mabo v Queensland (No 2) overturned the notion of Australia as terra nullius at the time of European occupation. terra nullius ceremony in Port Melbourne, Victoria, 25 April 2005. Ceremonies such as this are held in virtually every suburb and town in Australia.]] A gold rush began in Australia in the early 1850s, and the Eureka Stockade rebellion in 1854 was an early expression of nationalist sentiment. Between 1855 and 1890, the six colonies individually gained responsible government, managing most of their own affairs while remaining part of the British Empire. The Colonial Office in London retained control of some matters, notably foreign affairs, defence and international shipping. On 1 January 1901, federation of the colonies was achieved after a decade of planning, consultation and voting, and the Commonwealth of Australia was born, as a Dominion of the British Empire. The Australian Capital Territory (ACT) was formed from New South Wales in 1911 to provide a location for the proposed new federal capital of Canberra (Melbourne was the capital from 1901 to 1927). The Northern Territory was transferred from the control of the South Australian government to the Commonwealth in 1911. Australia willingly participated in World War I; many Australians regard the defeat of the Australian and New Zealand Army Corps (ANZACs) at Gallipoli as the birth of the nation—its first major military action. Much like Gallipoli the Kokoda Track Campaign is regarded by many as a nation defining battle from World War II. The Statute of Westminster 1931 formally ended most of the constitutional links between Australia and Britain, but Australia did not adopt the Statute until 1942. The shock of Britain's defeat in Asia in 1942 and the threat of Japanese invasion caused Australia to turn to the United States as a new ally and protector. Since 1951, Australia has been a formal military ally of the US under the auspices of the ANZUS treaty. After World War II, Australia encouraged mass immigration from Europe; since the 1970s and the abolition of the White Australia policy, immigration from Asia and other parts of the world was also encouraged. As a result, Australia's demography, culture and image of itself were radically transformed. The final constitutional ties between Australia and Britain ended in 1986 with the passing of the Australia Act 1986, ending any British role in the Australian States, and ending judicial appeals to the UK Privy Council. Although Australian voters rejected a move to become a republic in 1999 by a 55% majority, Australia's links to its British past are increasingly tenuous. Since the election of the Whitlam Government in 1972, there has been an increasing focus on the nation's future as a part of the Asia-Pacific region.

Politics

Whitlam Government was opened in 1988 replacing the provisional Parliament House building opened in 1927.]] The Commonwealth of Australia is a constitutional monarchy and has a parliamentary system of government. Queen Elizabeth II is the Queen of Australia, a role that is distinct from her position as Elizabeth II of the United Kingdom. The Queen is nominally represented by the Governor-General; although the Constitution gives extensive executive powers to the Governor-General, these are normally exercised only on the advice of the Prime Minister. The most notable exercise of the Governor-General's reserve powers outside the Prime Minister's direction was the dismissal of the Whitlam Government in the constitutional crisis of 1975. There are three branches of government.
- The legislature: the Commonwealth Parliament, comprising the Queen, the Senate (the Red house), and the House of Representatives (the Green house); the Queen is represented by the Governor-General, who in practice exercises little or no power over the Parliament.
- The executive: the Federal Executive Council (the Governor-General as advised by the executive councillors); in practice, the councillors are the prime minister and ministers of state, whose advice the Governor-General accepts, with rare exceptions.
- The judiciary: the High Court of Australia and other federal courts. The State courts became formally independent from the Judicial Committee of the Privy Council when the Australia Act was passed in 1986. The bicameral Commonwealth Parliament consists of the Queen, the Senate (the upper house) of 76 senators, and a House of Representatives (the lower house) of 150 members. Members of the lower house are elected from single-member constituencies, commonly known as 'electorates' or 'seats'. Seats in the House of Representatives are allocated to states on the basis of population. In the Senate, each state, regardless of population, is represented by 12 senators, with the ACT and the NT each electing two. Elections for both chambers are held every three years; typically only half of the Senate seats are put to each election, because senators have overlapping six-year terms. The party with majority support in the House of Representatives forms Government, with its leader becoming Prime Minister. There are three major political parties: the Labor Party, the Liberal Party and the National Party. Independent members and several minor parties—including the Greens, Family First and the Australian Democrats—have achieved representation in Australian parliaments, mostly in upper houses, although their influence has been marginal. Since the 1996 election, the Liberal/National Coalition led by the Prime Minister, John Howard, has been in power in Canberra. In the 2004 election, the Coalition won control of the Senate, the first time that a party (or coalition of governing parties) has done so while in government in more than 20 years. The Labor Party is in power in every state and territory. Voting is compulsory in each state and territory and at the federal level.

States and territories

Voting is compulsory Australia consists of six states, two major mainland territories, and other minor territories. The states are New South Wales, Queensland, South Australia, Tasmania, Victoria and Western Australia. The two major mainland territories are the Northern Territory and the Australian Capital Territory. In most respects, the territories function similarly to the states, but the Commonwealth Parliament can override any legislation of their parliaments. By contrast, federal legislation overrides state legislation only with respect to certain areas as set out in Section 51 of the Constitution; all residual legislative powers are retained by the state parliaments, including powers over hospitals, education, police, the judiciary, roads, public transport and local government. Each state and territory has its own legislature (unicameral in the case of the Northern Territory, the ACT and Queensland, and bicameral in the remaining states). The lower house is known as the Legislative Assembly (House of Assembly in South Australia and Tasmania) and the upper house the Legislative Council. The heads of the governments in each state and territory are called premiers and chief ministers, respectively. The Queen is represented in each state by a governor; an administrator in the Northern Territory, and the Governor-General in the ACT, have analogous roles. Australia also has several minor territories; the federal government administers a separate area within New South Wales, the Jervis Bay Territory, as a naval base and sea port for the national capital. In addition Australia has the following, inhabited, external territories: Norfolk Island, Christmas Island, Cocos (Keeling) Islands, and several largely uninhabited external territories: Ashmore and Cartier Islands, Coral Sea Islands, Heard Island and McDonald Islands and the Australian Antarctic Territory.

Foreign relations and military

Over recent decades, Australia's foreign relations have been driven by a close association with the United States, through the ANZUS pact and by a desire to develop relationships with Asia and the Pacific, particularly through ASEAN and the Pacific Islands Forum. In 2005 Australia secured an inaugural seat at the East Asia Summit following its accession to the Treaty of Amity and Cooperation. Australia is a member of the Commonwealth of Nations, in which the Commonwealth Heads of Government meetings provide the main forum for co-operation. Much of Australia's diplomatic energy is focused on international trade liberalisation. Australia led the formation of the Cairns Group and APEC, and is a member of the OECD and the WTO. Australia has pursued several major bilateral free trade agreements, most recently the US–Australia Free Trade Agreement. Australia is a founding member of the United Nations, and maintains an international aid program under which some 60 countries receive assistance. The 2005–06 budget provides A$2.5bn for development assistance; as a percentage of GDP, this contribution is less than that of the UN Millennium Development Goals. Australia's armed forces—the Australian Defence Force (ADF)—comprise the Royal Australian Navy (RAN), the Australian Army, and the Royal Australian Air Force (RAAF). All branches of the ADF have been involved in UN and regional peacekeeping (most recently in East Timor, the Solomon Islands and Sudan), disaster relief, and armed conflict, including the 2003 Invasion of Iraq. The government appoints the chief of the Defence Force from one of the armed services; the current chief is Air Chief Marshal Angus Houston. In 2005–06, the defence budget is A$17.5bn.

Geography and climate

Angus Houston Australia's 7,686,850 km² (2,967,909 mi²) landmass is on the Indo-Australian Plate. Surrounded by the Indian, Southern and Pacific oceans, Australia is separated from Asia by the Arafura and Timor seas. Australia has a total 25,760 km (16,007 mi) of coastline and claims an extensive Exclusive Economic Zone of 8,148,250 km² or 3,146,057 mi² (excluding the Australian Antarctic Territory). Climate is highly influenced by ocean currents, including the El Niño southern oscillation, which is correlated with periodic drought, and the seasonal tropical low pressure system that produces cyclones in northern Australia. By far the largest part of Australia is desert or semi-arid. Australia is the driest inhabited continent, the flattest, and has the oldest and least fertile soils. Only the south-east and south-west corners of the continent have a temperate climate. The northern part of the country, with a tropical climate, has a vegetation consisting of rainforest, woodland, grassland and desert. The Great Barrier Reef, the world's largest coral reef, lies a short distance off the north-east coast and extends for over 2,000 km (1,250 mi). The world's two largest monoliths are located in Australia, Mount Augustus in Western Australia is the largest and Uluru in central Australia is the second largest. At 2,228 m (7,310 ft), Mount Kosciuszko on the Great Dividing Range is the highest mountain on the Australian mainland, although Mawson Peak on the remote Australian territory of Heard Island is taller at 2,745 m (9,006 ft).

Flora and fauna

Heard Island of the wallaby is currently being sequenced; when the sequencing is completed, it will be a major contribution to marsupial biology.]] Although most of Australia is semi-arid or desert, it covers a diverse range of habitats, from alpine heaths to tropical rainforests. Because of the great age and consequent low levels of fertility of the continent, its extremely variable weather patterns, and its long-term geographic isolation, much of Australia's biota is unique and diverse. About 85% of flowering plants, 84% of mammals, more than 45% of birds, and 89% of in-shore, temperate-zone fish are endemic. Many of Australia's ecoregions, and the species within those regions, are threatened by human activities and introduced plant and animal species. The federal Environment Protection and Biodiversity Conservation Act 1999 is a legal framework used for the protection of threatened species. Numerous protected areas have been created to protect and preserve Australia's unique ecosystems, 64 wetlands are registered under the Ramsar Convention, and 16 World Heritage Sites have been established. Australia was ranked 13th in the World on the 2005 Environmental Sustainability Index. Environmental Sustainability Index.]] Most Australian plant species are evergreen and many are adapted to fire and drought, including the eucalypts and acacias. Australia has a rich variety of endemic legume species that thrive in nutrient-poor soils because of their symbiosis with Rhizobia bacteria and mycorrhizal fungi. Well-known Australian fauna include monotremes (the platypus and echidna), and a host of marsupials, including the koala, kangaroo, wombat, and birds such as the emu, cockatoo, and kookaburra. The dingo was introduced by Austronesian people that traded with Indigenous Australians around 4000 BCE. Many plant and animal species became extinct soon after human settlement, including the Australian megafauna; many more have become extinct since European settlement, among them the Thylacine (Tasmanian Tiger).

Economy

Thylacine Australia has a prosperous, Western-style mixed economy, with a per capita GDP slightly higher than those of the UK, Germany and France. The country was ranked third in the United Nations' 2005 Human Development Index and sixth in The Economist worldwide quality-of-life index 2005. In recent years, the Australian economy has been resilient in the face of global economic downturn. Rising output in the domestic economy has been offsetting the global slump, and business and consumer confidence remains robust. Australia's emphasis on reform is another key factor behind the economy's strength. In the 1980s, the Labor Party, led by Prime Minister Bob Hawke and Treasurer Paul Keating, started the process of modernising the Australian economy by floating the Australian dollar in 1983, and deregulating the financial system. Since 1996, the Howard government has continued the process of micro-economic reform, including the partial deregulation of the labour market and the privatisation of state-owned businesses, most notably in the telecommunications industry. Substantial reform of the indirect tax system was achieved in July 2000 with the introduction of a 10% Goods and Services Tax, which has slightly reduced the heavy reliance on personal and company income tax that still characterises Australia's tax system. The Australian economy has not suffered a recession since the early 1990s. As of July 2005, unemployment was 5.0% with 10,030,300 persons employed. The service sector of the economy, including tourism, education, and financial services, comprises 69% of GDP. Agriculture and natural-resources represent only 3% and 5% of GDP, respectively, but contribute substantially to Australia's export performance. Australia's largest export markets include Japan, China, the United States, South Korea and New Zealand. Areas of concern to some economists include the chronically high current account deficit and also high levels of net foreign debt.

Demographics

current account deficit Most of the estimated 20.4 million Australians are descended from 19th- and 20th-century immigrants, the majority from Britain and Ireland. Australia's population has quadrupled since the end of World War I , spurred by an ambitious immigration program. In 2001, the five largest groups of the 27.4% of Australians who were born overseas were from the United Kingdom, New Zealand, Italy, Vietnam and China. Following the abolition of the White Australia policy, numerous government initiatives have been established to encourage and promote racial harmony based on a policy of multiculturalism. Australia’s population has increased by about 60 times since European settlement. The self-declared indigenous population—including Torres Strait Islanders, who are of Melanesian descent—was 410,003 (2.2% of the total population) in 2001, a significant increase from the 1977 census, which showed an indigenous population of 115,953. Indigenous Australians have higher rates of imprisonment and unemployment, lower levels of education and life expectancies for males and females that are 17 years lower than those of other Australians. Perceived racial inequality is an ongoing political and human rights issue for Australians. human rights.]] In common with many other developed countries, Australia is experiencing a demographic shift towards an older population, with more retirees and fewer people of working age. A large number of Australians (759,849 for the period 2002–03) live outside their home country. Australia has maintained one of the most active immigration programs in the world to boost population growth. Most immigrants are skilled; the quota includes categories for family members and refugees. English is the official language, and is spoken and written in a distinct variety known as Australian English. According to the 2001 census, English is the only language spoken in the home for around 80% of the population. The next most common languages spoken at home are Chinese (2.1%), Italian (1.9%) and Greek (1.4%). A considerable proportion of first- and second-generation migrants are bilingual. It is believed that there were between 200 and 300 Australian Aboriginal languages at the time of first European contact. Only about 70 of these languages have survived, and all but 20 of these are now endangered. An indigenous language remains the main language for about 50,000 (0.02%) people. Australia has a sign language known as Auslan, which is the main language
