2000

This article is about the year 2000. For other uses of 2000, see 2000 (number) or 2000 (breakdancing move). 2000 (MM) is a leap year starting on Saturday of the Gregorian calendar. Popular culture also holds the year 2000 as the first year of the 21st century and the 3rd millennium. By strict interpretation of the Gregorian Calendar, however, this distinction falls to the year 2001. This is due to the fact that the first century began with the year 1, and there does not exist a year zero. The first century (or first 100 years AD) was from January 1, in the year one (1 AD) through December 31, in the year one-hundred (100 AD). The second century began on January 1, in the year one-hundred and one (101 AD). The year 2000 is also marked as:
- The International Year for a Culture of Peace.
- The World Mathematical Year. See also Wikipedia's almanac of events for this year.

Liberty Bell 7

Mercury 4 was a Mercury program manned space mission launched on July 21, 1961 using a Redstone rocket. Its capsule was named Liberty Bell 7 and performed a suborbital flight piloted by astronaut Virgil I. "Gus" Grissom. It reached an altitude of over 118.26 statute miles (190 km) and traveled about 300 miles (480 km). The Redstone was MRLV-8 and the spacecraft was Mercury spacecraft # 11, the first one with a centerline window instead of two portholes.

Crew

- Gus Grissom (flew on Mercury 4 & Gemini 3)

Backup Crew

- John Glenn

Mission Parameters

- Mass: 1286 kg
- Maximum Altitude: 190.39 km
- Range: 486.15 km
- Launch Vehicle: Redstone rocket

Liberty Bell 7

Mercury spacecraft # 11, was designated to fly the second manned suborbital flight in October, 1961. It came off McDonnell's St. Louis production line in May 1960. Spacecraft # 11 was the first Mercury operational spacecraft with a centerline window. It was closer to the final orbital version than was Alan Shepard's Freedom 7.

Explosive hatch

Spacecraft # 11 also had a new explosive side hatch. This would allow an astronaut to exit the spacecraft quickly in the event of an emergency. Emergency personnel could also trigger the explosive hatch from outside the spacecraft by pulling on an external lanyard. The original exit procedure was to climb out through the antenna compartment, after removing a small pressure bulkhead. This was a difficult and slow procedure. Removal of an injured or unconscious astronaut through the top hatch would be nearly impossible. The original side hatch was bolted shut with 70 bolts and covered with several spacecraft shingles. It was a slow process to open the original hatch. McDonnell engineers came up with two different quick release hatches for the Mercury spacecraft. One with a latch, used on Ham's MR-2 and Shepard's MR-3 missions. The other design was an explosive release hatch. The quick release latching hatch weighed 69 pounds (31 kg), too much of a weight addition to use on the orbital version of the spacecraft. The explosive hatch design used the 70 bolts of the original design; but each quarter-inch (6.35 mm) titanium bolt had a 0.06 inch (1.5 mm) hole bored into it to provide a weak point. A mild detonating fuse (MDF) is installed in a channel between the inner and outer seal around the periphery of the hatch. When the MDF is ignited, the resulting gas pressure between the inner and outer seal causes the bolts to fail in tension. There were two ways to fire the explosive hatch during recovery. On the inside of the hatch was a knobbed plunger. The pilot could remove a pin and press the plunger with a force of five or six pounds force (25 N). This would detonate the explosive charge which would shear off the 70 bolts and propel the hatch 25 feet (8 m) away in 1 second. If the pin was left in place, a force of 40 pounds (180 N) was required to detonate the hatch. An outside rescuer could blow open the hatch by removing a small panel near the hatch and pull a lanyard. The explosive hatch weighed only 23 pounds (10 kg).

Window

The new rectangular window on spacecraft # 11 replaced the two 10 inch (254 mm) side portholes that were on Freedom 7. The Corning Glass Works of Corning, New York, designed and developed the multilayered panes that made up the new window. The outer pane was Vycor glass was 0.35 inch (8.9 mm) thick. It could withstand temperatures of 1500 to 1800 °F (820 to 980 °C). The inner pane was made up of three inner glass panels bonded to make the inner pane. One panel was a 0.17 inch (4.3 mm) thick sheet of Vycor, the two others made of tempered glass. This new window assembly was as strong as any part of the spacecraft pressure vessel.

Controls

The manual controls for Mercury 4 incorporated a new rate stabilization control system. This allowed fine control of spacecraft attitude movements by small turns of the hand controller. Previously a lot of jockeying of the device was needed to attain the desired attitude. This rate damping or rate augmentation system gave finer and easier handling qualities and a redundant means of firing the pitch, yaw, and roll thrusters. Before the Mercury 4 flight, Lewis Research Center and Space Task Group engineers had determined that firing the posigrade rockets into the booster-spacecraft adapter, rather than in the open, developed 78 percent greater thrust. This achieved a greater spacecraft-booster separation through a kind of "pop-gun" effect. By using this technique, the spacecraft separated at velocity of about 28.1 feet per second (9 m/s) rather than 15 feet per second (5 m/s) using the old procedure. Mercury 4 flight would take advantage of this new procedure. Additional hardware changes to Mercury 4 were a redesigned fairing for the spacecraft-Redstone adapter clamp-ring and additional foam padding was added to the head area of the contour couch. The fairing changes and additional foam were used to reduce vibrations the pilot experienced during the boost phase of flight. The spacecraft instrument panel was rearranged to provide a better eye scan pattern.

Mission description

In January, 1961, NASA's Director of the Space Task Group, Robert Gilruth, told Gus Grissom that he would be the primary pilot for Mercury 4. John Glenn was the backup pilot for the mission. Redstone launch vehicle MRLV-8 arrived at Cape Canaveral on June 8, 1961. A mission review on July 15, 1961 pronounced Redstone MRLV-8 and Mercury spacecraft # 11 ready to go for the Mercury 4 mission. Also, on July 15, 1961 Gus Grissom announced he would name Mercury 4, Liberty Bell 7. Grissom said the name was an appropriate call-sign for the bell-shaped capsule. He also said the name was synonymous with "freedom". As a tribute to the original Liberty Bell, a "crack" was painted on the side of the capsule. The Mercury 4 mission was planned as a repeat of MR-3. It was to reach an apogee of 116 miles (187 km). The planned range was 299 miles (481 km). Grissom would experience a maximum acceleration of 6.33 g (62 m/s²) and deceleration of 10.96 g (107 m/s²). The launch of Liberty Bell 7 was first planned for July 16. The cloud cover was too thick and the launch was postponed until July 18. On July 18, it was again postponed due to weather. Both times, the pilot had not yet boarded the spacecraft. On July 19, 1961, Grissom was aboard the Liberty Bell 7 when the flight was delayed again due to weather. At that point, it had just 10 minutes 30 seconds to go before launch. On the morning of July 21, 1961, Gus Grissom entered the Liberty Bell 7 at 8:58 UTC and the 70 hatch bolts were put in place. At 45 minutes prior to the scheduled launch, a pad technician discovered that one of the hatch bolts was misaligned. During a 30 minute hold that was called, McDonnell and NASA Space Task Group engineers decided that the 69 remaining bolts should be sufficient to hold the hatch in place and blow it at the appropriate time. The misaligned bolt was not replaced. The Liberty Bell 7 was launched at 12:20:36 UTC, July 21, 1961.

Liftoff

Grissom later admitted at the postflight debriefing that he was "a bit scared" at liftoff, but he added that he soon gained confidence along with the acceleration increase. Hearing the engine roar at the pedestal, he thought that his elapsed-time clock had started late. Like Shepard, he was amazed at the smooth quality of the liftoff, but then he noticed gradually more severe vibrations. These were never violent enough to impair his vision. Grissom's cabin pressure sealed off at the proper altitude, about 27,000 feet (8.2 km), and he felt elated that the environmental control system was in good working order. The suit and cabin temperature, about 57.5 and 97 °F (14 and 36 °C), respectively, were quite comfortable. Watching his instruments for the pitch rate of the Redstone, Grissom saw it follow directions as programmed, tilting over about one degree per second. Under a 3 g (29 m/s²) acceleration on the up-leg of his flight, Grissom noticed a sudden change in the color of the horizon from light blue to jet black. His attention was distracted by the noise of the tower-jettison rocket firing on schedule. The pilot felt the separation and watched the tower through the window as it drifted off, trailing smoke, to his right. At two minutes and 22 seconds after launch, the Redstone's Rocketdyne engine cut off after building a velocity of 6561 feet per second (1,969 m/s). Grissom had a strong sensation of tumbling during the transition from high to zero acceleration, and, while he had become familiar with this sensation in centrifuge training, for a moment he lost his bearings. The Redstone coasted for 10 seconds after its engine cut off; then a sharp report signaled that the posigrade rockets were popping the capsule loose from the booster. Although Grissom peered out his window throughout his ship's turnaround maneuver, he never caught sight of his launch vehicle.

Flight

With turnaround accomplished, the Air Force jet pilot for the first time became a space pilot, assuming manual-proportional control. A constant urge to look out the window made concentrating on his control tasks difficult. He told Shepard back in Mercury Control that the panorama of Earth's horizon, presenting an 800 mile (1,300 km) arc at peak altitude, was fascinating. His instruments rated a poor second to the spectacle below. Turning reluctantly to his dials and control stick, Grissom made a pitch movement change but was past his desired mark. He jockeyed the handcontroller stick for position, trying to damp out all oscillations, then made a yaw movement and went too far in that direction. By the time the proper attitude was attained, the short time allocated for these maneuvers had been used, so he omitted the roll movement altogether. The manual controls impressed Grissom as very sluggish when compared to the Mercury procedures trainer. Then he switched to the new rate command control system and found perfect response, although fuel consumption was high. After the pitch and yaw maneuvers, Grissom made a roll-over movement so he could see the ground from his window. Some land beneath the clouds (later determined to be western Florida around the Apalachicola area) appeared in the hazy distance, but the pilot was unable to identify it. Suddenly Cape Canaveral came into view so clearly that Grissom found it hard to believe that his slant-range was over 150 miles (240 km). He saw Merritt Island, the Banana River, the Indian River, and what appeared to be a large airport runway. South of Cape Canaveral, he saw what he believed to be West Palm Beach.

Reentry

With Liberty Bell 7 at an altitude of 118.26 miles (190.32 km), it was now time to position the spacecraft in its reentry attitude. Grissom had initiated the retrorocket sequence and the capsule was arcing downward. His pulse reached 171 beats per minute. Retrofire gave him the distinct and peculiar feeling that he had reversed his backward flight through space and was actually moving face forward. As he plummeted downward, he saw what appeared to be two of the spent retrorockets pass across the periscope view after the retrorocket package had been jettisoned. Pitching the spacecraft over into a reentry attitude of 14 degrees from Earth-vertical, the pilot tried to see the stars out his observation window. Instead the glare of sunlight filled his capsule, making it difficult to read the panel dials, particularly those with blue lights. Grissom felt that he would not have noticed the 0.05 g (0.5 m/s²) light if he had not known it was about to flash on. Reentry presented no problem. Grissom could not feel the oscillations following the acceleration buildup; he could only read them on the rate indicators. Meanwhile he continued to report to the Mercury Control Center on his electric current reading, fuel quantity, acceleration, and other instrument indications. Condensation and smoke trailed off the heatshield at about 65,000 feet (20 km) as Liberty Bell 7 plunged back into the atmosphere. The drogue parachute deployed on schedule at 21,000 feet (6.4 km). Grissom said he saw the deployment and felt some resulting pulsating motion, but not enough to worry him. Main parachute deployment occurred at 12,300 feet (3.7 km), which was about 1,000 feet (300 m) higher than the design nominal altitude. Watching the main chute unfurl, Grissom spotted a six inch (150 mm) L-shaped tear and another two inch (50 mm) puncture in the canopy. Although he worried about them, the holes grew no bigger and his rate of descent soon slowed to about 28 feet per second (9 m/s). Dumping his peroxide control fuel, the pilot began transmitting his panel readings.

Splashdown

A "clunk" confirmed that the landing bag had dropped in preparation for impact. Grissom then removed his oxygen hose and opened his visor but deliberately left the suit ventilation hose attached. Impact was milder than he had expected, although the capsule heeled over in the water until Grissom was lying on his left side. He thought he was facing downward. The capsule gradually righted itself, and, as the window cleared the water, Grissom jettisoned the reserve parachute and activated the rescue aids switch. Liberty Bell 7 still appeared watertight, although it was rolling badly with the swells. Preparing for recovery, he disconnected his helmet and checked himself for debarkation. The neck dam did not unroll easily; Grissom tinkered with his suit collar to ensure his buoyancy if he had to get out of the spacecraft quickly. When the recovery helicopters, which had taken to the air at launch time and visually followed the contrails and parachute descent, were still about two miles (3 km) [373] from the impact point, which was only three miles (5 km) beyond the bullseye, Lieutenant James L. Lewis, pilot of the primary recovery helicopter, radioed Grissom to ask if he was ready for pickup. He replied that he wanted them to wait five minutes while he recorded his cockpit panel data. Using a grease pencil with the pressure suit gloves was awkward, and several times the suit ventilation caused the neck dam to balloon, but the pilot simply placed his finger between neck and dam to allow the air to escape. After logging the panel data, Grissom asked the helicopters to begin the approach for pickup. He removed the pin from the hatch-cover detonator and lay back in the dry couch. "I was lying there, minding my own business," he said afterward, "when I heard a dull thud." The hatch cover blew away, and salt water swished into the capsule as it bobbed in the ocean. The third man to return from space was faced with the first serious emergency; Liberty Bell 7 was shipping water and sinking fast. Grissom had difficulty recollecting his actions at this point, but he was certain that he had not touched the hatch-activation plunger. He doffed his helmet, grasped the instrument panel with his right hand, and scurried out the sloshing hatchway. Floating in the sea, he was thankful that he had unbuckled himself earlier from most of his harness, including the chest restraints. Otherwise he might not have been able to abandon ship. Lieutenant John Reinhard, copilot of the nearest recovery helicopter, reported afterward that the choppers were making their final approach for pickup. He was preparing to cut the capsule's antenna whip (according to a new procedure) with a squib-actuated cutter at the end of a pole, when he saw the hatch cover fly off, strike the water at a distance of about five feet (1.5 m) from the hatch, and then go skipping over the waves. Next he saw Grissom's head appear, and the astronaut began climbing through the hatch. Once out, the pressure-suited spaceman swam away. Instead of turning his attention to Grissom, Lewis completed his approach to the sinking spacecraft, as both he and Reinhard were intent on capsule recovery. This action was a conditioned reflex based on past training experience. While training off the Virginia beaches the helicopter pilots had noted that the astronauts seemed at home in and to enjoy the water. So Reinhard quickly clipped the high-frequency antenna as soon as the helicopter reached Liberty Bell 7. Throwing aside the antenna cutting device, Reinhard picked up the shepherd's hook recovery pole and carefully threaded the crook through the recovery loop on top of the capsule. By this time Lewis had lowered the helicopter to assist Reinhard in his task to a point that the chopper's three wheels were in the water. Liberty Bell 7 sank out of sight, but the pickup pole twanged as the attached cable went taut, indicating to the helicopter pilots that they had made their catch. Reinhard immediately prepared to pass the floating astronaut the personnel hoist. But at that moment Lewis called a warning that a detector light had flashed on the instrument panel, indicating that metal chips were in the oil sump [375] because of engine strain. Considering the implication of impending engine failure, Lewis told Reinhard to retract the personnel hoist while he called the second chopper to retrieve the pilot. Meanwhile Grissom, having made certain that he was not snared by any lines, noticed that the primary helicopter was having trouble raising the submerged spacecraft. He swam back to the capsule to see if he could assist but found the cable properly attached. When he looked up for the personnel line, he saw the helicopter start to move away. Suddenly Grissom realized that he was not riding as high in the water as he had been. All the time he had been in the water he kept feeling air escape through the neck dam. The more air he lost, the less buoyancy he had. Moreover, he had forgotten to secure his suit inlet valve. Swimming was becoming difficult, and now with the second helicopter moving in he found the rotor wash between the two aircraft was making swimming more difficult. Bobbing under the waves, Grissom was scared, angry, and looking for a swimmer from one of the helicopters to help him tread water. Then he caught sight of a familiar face, that of George Cox, aboard the second helicopter. Cox was the copilot who had retrieved both the chimpanzee Ham and Astronaut Shepard. With his head barely above water, Grissom found the sight of Cox heartening. Cox tossed the "horse-collar" lifeline straight to Grissom, who immediately wrapped himself into the sling backwards. Lack of orthodoxy mattered little to Grissom now, for he was on his way to the safety of the helicopter, even though swells dunked him twice more before he got aboard. His first thought was to get a life preserver on. Grissom had been either swimming or floating for a period of only four or five minutes, "although it seemed like an eternity to me," as he said afterward. As the first helicopter moved away from Grissom, it struggled valiantly to raise the spacecraft high enough to drain the water from the impact bag. Once the capsule was almost clear of the water, but like an anchor it prevented the helicopter from moving forward. The flooded Liberty Bell 7 weighed over 5,000 pounds (2,300 kg), a thousand pounds (450 kg) beyond the helicopter's lifting capacity. The pilot, watching his insistent red warning light, decided not to chance losing two craft in one day. He finally cast loose, allowing the spacecraft to sink swiftly. Martin Byrnes, aboard the carrier, suggested that a marker be placed at the point so that the capsule might be recovered later. Rear Admiral J. E. Clark advised Byrnes that in that area the depth was about 2,800 fathoms (5.1 km). Substantial controversy ensued as Grissom reported that the hatch had blown prematurely without his authorization. Engineering teams concluded this was unlikely. Mrs. Grissom was not invited to the White House as per the forming tradition with Shepard's wife upon his successful mission completion. Subsequent independent technical review of the incident has raised doubts as to the veracity of the incident report conclusions that Grissom blew the hatch and was responsible for the loss of the spacecraft. There is strong evidence that the Astronaut Office didn't accept Grissom's guilt in the fact that he was chosen to command the first Gemini flight. Several years later, during an interview on April 12, 1965, Grissom said he thought the hatch may have been triggered because the external release lanyard came loose. On Liberty Bell 7, the external release lanyard was only held in place by a single screw. It was better secured on later flights. Ironically, the inability to open a hatch swiftly contributed to the death of Grissom, as well as Ed White and Roger B. Chaffee, in the Apollo 1 launch-pad fire.

Recovery of Liberty Bell 7

One day shy of the 38th anniversary (July 20, 1999), of Mercury 4's suboribital flight, a team led by Curt Newport and financed by the Discovery Channel, lifted the Liberty Bell 7 capsule off the floor of the Atlantic ocean and onto the deck of a recovery ship. The capsule was found after a 14-year effort by Newport and his team at a depth of nearly 15,000 feet (4.5 km), 300 nautical miles (550 km) southeast of Cape Canaveral and was in surprisingly good condition. Some of the interior aluminium panels showed deterioration but some fabric pieces, including Grissom's personal parachute were perfectly intact. The recovery failed to answer some of the questions surrounding the prematurely blown hatch. The recovery team ran out of time and was not able to continue the search for the hatch itself. A camera that was running during the flight was located but was found broken open and the film inside was damaged beyond repair. After Liberty Bell 7 was secured in the deck of the recovery ship, experts removed and disposed of an explosive device that was supposed to detonate in the event of the capsules sinking but which failed to explode. After the capsule was made safe, it was placed in a container filled with seawater to prevent further corrosion. The Kansas Cosmosphere and Space Center disassembled and cleaned the capsule and keeps it on display in their museum. Liberty Bell 7 was recovered exactly 30 years to the day after man first landed on the moon.

Mercury Redstone Sub-Orbital Flight Events

Category:Human spaceflights Category:Mercury program

Gemini 3

Gemini 3 was a 1965 manned space flight in NASA's Gemini program. It was the first manned Gemini flight, the ninth manned American flight and the 17th manned spaceflight of all time (includes X-15 flights over 100 kilometres).

Crew

- Virgil I. Grissom (flew on Mercury 4, Gemini 3, & Apollo 1), Command Pilot
- John W. Young (flew on Gemini 3, Gemini 10, Apollo 10, Apollo 16, STS-1, & STS-9), Pilot

Backup crew

- Walter M. Schirra, Command Pilot
- Thomas P. Stafford, Pilot

Mission parameters

- Mass: 3,236.9 kg
- Perigee: 161.2 km
- Apogee: 224.2 km
- Inclination: 32.6 degrees
- Period: 88.3 minutes
- First orbital maneuver by manned spacecraft On March 23, 1965 at 15:57:00 UTC, at the end of the first orbit, over Corpus Christi, Texas, a 1 minute 14 second burn of the Orbit attitude and maneuvering system (OAMS) engines gave a delta-V of 15.5 meters per second. The orbit was changed from 161.2 km x 224.2 km, period 88.3 minutes to an orbit of 158 km x 169 km, period 87.8 minutes.

Objectives

This first manned flight of the Gemini spacecraft was very much a test flight. In a playful reference to the Broadway hit The Unsinkable Molly Brown, Grissom nicknamed the Gemini 3 spacecraft "Molly Brown," hoping that it would not duplicate his experience with Liberty Bell 7. (It was the last Gemini to be named by an astronaut. All subsequent flights in the program were designated by a Roman numeral.) The mission's primary goal was to test the new, maneuverable Gemini spacecraft. In space, the crew fired thrusters to change the shape of their orbit, shift their orbital plane slightly, and drop to a lower altitude. Other firsts were achieved on Gemini 3: two people flew aboard an American spacecraft; the first manned re-entry where the spacecraft was able to produce lift to change its touchdown point.

Flight

The only major incident during the orbital phase involved a contraband corned beef sandwich that Young had snuck on board. The crew each took a few bites before the sandwich had to be restowed. The crumbs it released could have wreaked havoc with the craft's electronics, so the crew were reprimanded when they returned to Earth. Other crews were warned not to pull the same type of stunt again. corned beefTwo small failures occurred in-orbit. The first was an experiment testing the Synergistic Effect of Zero Gravity on Sea Urchin Eggs. A lever essential to the experiment broke off when pulled. The second involved the photographic coverage objective. It was only partially successful due to an improper lens setting on the 16mm camera. The crew made their first orbit change an hour and a half into the flight. The burn lasted 75 seconds and moved them from a 122 by 175 kilometer orbit to a nearly circular one with a drop in speed of 15 metres per second. The second burn was 45 minutes later when the orbital inclination was changed by 0.02 degrees. The last burn came during the third orbit when the perigee was lowered to 72 kilometres. This meant that even if retrorockets had failed, they would still have reentered. When reentry finally occurred, crew commented that even the colours matched ground simulations. On descent, the capsule shifted from a vertical to horizontal attitude under its parachutes. The change was so sudden that Grissom cracked his faceplate on the control panel in front of him. The craft landed eventually 84 kilometers short of its intended splashdown point. Wind tunnel testing incorrectly predicted the craft's ability to compensate for course deviation. When the crew discovered the error, they decided to stay in the capsule, not wanting to open the hatch before the arrival of the recovery ship. The crew spent an uncomfortable half an hour in a spacecraft never designed to be a boat. The Gemini 3 mission was supported by the following United States Department of Defense resources: 10,185 personnel, 126 aircraft and 27 ships.

Insignia

The mission insignia was not worn by the flight crew as a patch, like those from Gemini 5 onwards. The Gemini 3 Molly Brown logo was designed and minted on gold plated, sterling silver, 1-inch (25-mm) medallions. The crew carried a number of these medallions into space to give to their families and friends. The same design was imprinted on the cover of Gus Grissom's book, GEMINI, and John Young was seen wearing the Molly Brown logo as a patch on his flightsuit as late as 1981. The name "Molly Brown" was chosen by Grissom as a reference to the sinking of Liberty Bell 7; NASA officials found the slightly sarcastic reference embarrassing, and astronauts were not allowed to name their spacecraft again until Apollo 9 when for the first time, two spacecraft would be operating independently as part of the same mission.

Capsule location

The capsule is on display at the Grissom Memorial, Spring Mill State Park, Mitchell, Indiana.

Symbol

There is no universally agreed symbol but the following are used:
- square mile
- sq mile
- sq mi
- sq m (this can be confused with square metre)
- mile²

Conversions

1 square mile is equivalent to:
- 27 878 400 square feet
- 640 acres
- 2 589 988.11 square metres
- 2.589 988 11 square kilometres In the Public Land Survey System of the US and the Dominion Land Survey of Canada, the size of a standard section of land is one square mile.

Census

A census is the process of obtaining information about every member of a population (not necessarily a human population). It can be contrasted with sampling in which information is only obtained from a subset of a population. As such it is a method used for accumulating statistical data, and it is also vital to democracy (voting).

Ancient and medieval censuses

Rome conducted censuses to determine taxes (see Censor). The Bible relates stories of several censuses. The Book of Numbers describes a divinely-mandated census that occurred when Moses led the Israelites from Egypt. A later census called by King David of Israel, referred to as the "numbering of the people," incited divine retribution (for being militarily motivated or perhaps displaying lack of faith in God). A Roman census is also mentioned in one of the best known passages of the Bible in the Gospel of Luke. The world's oldest extant census comes from China during the Han Dynasty. Taken in the fall of 2 AD, it is considered by scholars to be quite accurate. At that time there were 57.5 million living in Han China, the world's largest population. The second oldest preserved census is also from the Han, dating back to 140 AD, when only a bit more than 48 million people were recorded. Mass migrations into what is today southern China are believed to be behind this massive demographic decline. In the Middle Ages, the most famous census is the Domesday Book, undertaken in 1086 by William I of England "to find out ... what or how much each landholder had in land and livestock, and what it was worth," so that he could properly tax the land he had recently conquered. In 1183, a census was taken of the crusader Kingdom of Jerusalem, to ascertain the number of men and amount of money that could possibly be raised against an invasion by Saladin, sultan of Egypt and Syria.

Modern censuses

Australia

The Australian census is run by the Australian Bureau of Statistics. It is carried out every five years, the last one being on August 7, 2001 and the next planned census is August 8, 2006.

Brazil

The Brazilian census is carried out by IBGE, the Brazilian Institute of Geography and Statistics, every 10 years. The last one was in 2000.

Canada

The Canadian census is run by Statistics Canada. The first census conducted in Canada was conducted in 1666, by French intendant Jean Talon, when he took a census to ascertain the number of people living in New France. In 1871, Canada's first formal census was conducted, which counted the population of Nova Scotia, Ontario, New Brunswick, and Quebec. In 1918, the Dominion Bureau of Statistics was formed. In 1971, Statistics Canada was formed to replace the Dominion Bureau of Statistics, and consequently, took over its census job. Censuses in Canada are conducted in five year intervals. The latest census was conducted in 2001 and the next planned census is 2006. Censuses taken in mid-decade (e.g. 1976, 1986, 1996, etc.) are referred to as quinquennial censuses. Others are referred to as decennial censuses. The first quinquennial census was conducted in 1956. See also: Canada 2001 Census

Costa Rica

Costa Rica carried out its 9th population census in 2000. INEC, National Institute of Statistics and Census is in charge of conduct these census. Past Costa Rican censuses were realized in 1864, 1883, 1892, 1927, 1950, 1963, 1973 and 1984.

Denmark

The first Danish census was in 1700-1701, and contained statistical information about adult men. Only about half of it still exists. A census of school children was taken during the 1730s. Following these early undertakings, the first census to attempt completely covering all citizens (including women and children who had previously been listed only as numbers) of Denmark-Norway was taken in 1769 [http://www.rhd.uit.no/census/ft1769.html]. At that point there were 797 584 citizens in the kingdom. Georg Christian Oeder took a statistical census in 1771 which covered Copenhagen, Sjælland, Møn, and Bornholm. After that, censuses followed somewhat regularly in 1787, 1801, and 1834, and between 1840 and 1860, the censuses were taken every five years, and then every ten years until 1890. Special censuses for Copenhagen were taken in 1885 and 1895. In the 20th century, censuses were taken every five years from 1901 to 1921, and then every ten years from 1930. The last census was taken in 1950. Currently, Det Centrale Personregister is doing the censuses using their register of Danish citizens. It is possible to search a portion of the Danish censuses online at [http://ddd.dda.dk/ Dansk Demografisk Database], and also view scanned versions at [http://www.arkivalieronline.dk/ Arkivalier Online].

France

Napoleon Bonaparte began the census in France as a means of determining the number of potential soldiers under his rule. Today, the census in France is carried out by INSEE. Since 2004, a partial census is carried out every year, and the results published as averages over 5 years.

Germany

The first large-scale census in the German Empire took place in 1895. Attempts at introducing a census in Germany sparked strong popular resentment in the 1980s since many quite personal questions were asked. Some campaigned for a boycott. In the end the Constitutional Court stopped the census in 1980 and 1983. The last census was in 1987. Germany has since used population samples in combination with statistical methods, in place of a full census.

Greece

Census takes place every 10 years and is carried out by the National Statistical Service of Greece [http://www.statistics.gr]. Last census was in 2001.

India

The decennial census of India is the primary source of information about the demographic characteristics of the population of India which is the second biggest country of the world in terms of population. The first census in India is dated 1872. It started as far back as in 1860 and was finished in 1871. Starting from there, a population census has been carried out every 10 years, latest being the fourteenth in February - March 2001. Census is carried out by the office of the Registrar General and Census Commissioner, India, Delhi under the Census of India Act, 1948. The act gives Central Government many powers like to notify a date for Census, power to ask for the services of any citizen for census work. The law makes it compulsory for every citizen to answer the census questions truthfully. The Act provides penalties for giving false answer or not giving answers at all to the census questionnaire. One of the most important provisions of law is the guarantee for the maintenance of secrecy of the information collected at the census of each individual. The census records are not open to inspection and also not admissible in evidence. Census happens in two phases, first House Listing and House Numbering Operations and second actual population enumeration phase. Census is carried out by the canvassing method. In this method, each and every household is visited and the information is collected by a specially trained enumerator. 9th February 2001, the first day of the 2001 census was celebrated as the census day.

Italy

The census in Italy is carried out by ISTAT every 10 years. The last four were in 1971, 1981, 1991, 2001.

Japan

Japan collects census information every five years. The figures show the English translation of the 2005 census form. The form solicits information on name, sex, relationship to head of household, year and month of birth, marital status, nationality, number of members of household, type and nature of dwelling, floor area of dwelling, number of hours worked during the week prior to October 1, employment status, name of employer and type of business, and kind of work.

Latvia

The most recent census in Latvia was in 2000. Before that, it was about 6 censuses, most part of these previous censuses was in the USSR time. The census in Latvia is carried out by Centrālā Statistikas Pārvalde (Central Statistical Bureau).

New Zealand

The census in New Zealand is carried out by Statistics New Zealand (Te Tari Tatau), every five years. The last was in 2001, the next will be in 2006. See New Zealand Census of Population and Dwellings.

Poland

The census in Poland is carried out by GUS every circa 10 years. The last one occurred in 2002.

Portugal

The census in Portugal is carried out by INE every 10 years. The last one occurred in 2001.

Romania

The first census in Romania was carried out in 1859. Nowadays it is carried every ten years by the Institutul Naţional de Statistică (INSSE). The last one occurred in 2002.

Russia/USSR

In Russia, the first All-Russia Population Census was carried out in 1897. All-Union Population Censuses were carried out in the USSR (which included RSFSR and the other republics) in 1920, 1926, 1939, 1959, 1970, 1979, and 1989). The first (post-Soviet) All-Russia Population Census was carried out in 2002. Next census is tentatively planned for 2010. Currently, the census is the responsibility of the [http://www.gks.ru Federal State Statistics Service.]

South Africa

The census in South Africa is carried out every 5 years by Statistics South Africa. The only two to date were in 1996 and 2001.

Ukraine

The first post-soviet census in Ukraine was carried out by [http://www.ukrcensus.gov.ua/eng/ State Statistics Committee of Ukraine] in 2001, 12 years after the last All-Union census in 1989.

United Kingdom

In the 7th century, Dalriada (now Scotland) was the first territory in what is now the UK to conduct a census, with what was called the "Tradition of the Men of Alba" (Senchus fer n'Alba'). England took its first Census when the Domesday Book was compiled in 1086 for tax purposes. The UK census as we know it today started in 1801 (championed by John Rickman who managed the first four up to 1831), partly to ascertain the number of men able to fight in the Napoleonic wars. Rickman's 12 reasons - set out in 1798 and repeated in Parliamentary debates - for conducting a UK census included the following justifications:
- 'the intimate knowledge of any country must form the rational basis of legislation and diplomacy'
- 'an industrious population is the basic power and resource of any nation, and therefore its size needs to be known'
- 'the number of men who were required for conscription to the militia in different areas should reflect the area's population'
- 'there were defence reasons for wanting to know the number of seamen'
- 'the need to plan the production of corn and thus to know the number of people who had to be fed'
- 'a census would indicate the Government's intention to promote the public good' and
- 'the life insurance industry would be stimulated by the results.' The census has been conducted every ten years since 1801 and most recently in 2001. The first four censuses (1801-1831) were mainly statistical (that is, they were mainly headcounts and contained virtually no personal information). The 1841 Census was the first to record names of all individuals in a household or institution. Because of World War II, there was no census in 1941. However, following the passage into law (on 5 September 1939) of the National Registration Act a population count was carried out on 29 September 1939, which was, in effect, a census. The census is undertaken by the government for policy and planning purposes, and the (statistical) information is also sold to interested parties. Public access to the census returns is restricted under the terms of the 100-year rule and the most recent returns made available to researchers are those of the 1901 Census. The census is usually very accurate, and with a fine of up to £1,000 for those who do not complete it, filled in by a high percentage of the population. An exception may have been the census conducted during the years of the poll tax (1991), when some people avoided it in case it was used for enforcing the tax. The 2001 census was the first year in which the government asked about religion. Perhaps encouraged by a chain letter that started in New Zealand, 390,000 people entered their religion as Jedi Knight (more than either Sikhs, Buddhists or Jews), with some areas registering up to 2.6% of people as Jedi.

The United States Constitution mandates that the census be taken at least once every ten years (U.S. Congress could require a more frequent census by legislation), and that the number of members of the House of Representatives from each state be determined accordingly. In addition, Census Bureau statistics are used for apportioning Federal funding for many social and economic programs. But there is not a federal census legislation (nor for federal voting). The first U.S. Census was taken in 1790 by the local U.S. Marshals. Census-takers went door-to-door and recorded the number of people in each household, and the name of the head of the household. Slaves were counted, but for apportionment purposes each counted as only three-fifths of a citizen. American Indians being neither taxed nor considered during apportionment, were not counted. The first census counted 3.9 million people, less than half the population of New York City in 2000. The 2000 census counted over 281 million people. In 1902, a Public Law established the Census Bureau as a permanent Federal agency. Until the 2010 census, there were two forms of questionnaire – long and short. Currently, the plan is to replace the Long form in 2010 with the American Community Survey (ACS), but funding for ACS is not assured, in which case there may be a long form in the 2010 census. Computer algorithms (based on complex sampling rules) determine which form was mailed to a given household (in practice, of those households whose locations are on the Census Master Address List), one in six receiving the long form. This was supplemented by census workers who go door-to-door to talk to people who fail to return the forms. In addition to a simple count of residents, the Census Bureau collects a variety of statistics, on topics ranging from ethnicity to the presence of indoor plumbing. While some critics claim that census questions are an invasion of privacy, the data collected by every question is either required to enforce some federal law (such as the Voting Rights Act) or is required to administer some federal program. Congress gives approval to every question asked on the Census. Despite a massive effort, the Census Bureau has never been able to count every individual, leading to controversy about whether to use statistical methods to supplement the numbers for some purposes, as well as arguments over how to improve the actual head count. The Supreme Court has ruled that only an actual head count can be used to apportion Congressional seats; however, cities and minority representatives have complained that urban residents and minorities are undercounted. In several cases, the Census Bureau will recount an area with disputed figures, provided the local government pays for the time and effort. The State of Utah protested the figures of the 2000 decennial census because it lost a seat in the House of Representatives to North Carolina. Had the Census Bureau been able to count the numbers of Utahns living overseas, including many Mormon missionaries, Utah would have retained the seat. To minimize the burden on individuals and to provide improved data, the Bureau is preparing several alternative methods for gathering economic, demographic, and social information, including the American Community Survey and record linking of depersonalized administrative records with other administrative records and Census Bureau surveys. By law (92 Stat. 915, Public Law 95-416, enacted on October 5, 1978), census records are sealed for 72 years; in an era when life expectancy was under 60 years, this attempts to protect individual's privacy by prohibiting the release of such information during their expected lifetimes. Thus, the most recent Census released to the public was the 1930 Census, released in 2002. Indexes to some of the U.S. Censuses have been produced over the years, making the process of searching old census records much easier. Some indexes of census records have been produced by amateur volunteer genealogists. Due to the sheer volume of information, and the manual methodologies involved, the indexing used to be limited to the head-of-household. These indexes were published in bound volumes and are often available in regional libraries along with microfilm rolls that can be researched. While valuable, indexes produced from these censuses can be problematic to use. The original census records from this era were completed by hand by census enumerators; this leads to problems in handwriting recognition and variations in spelling of surnames within the original documents. The 1880 to 1920 censuses have indexes of last names, produced using the Soundex system; the indexing project was performed by the Works Progress Administration. The Soundex system is tolerant of variations in spelling; names with similar sounds but different spellings have the same encoding. The chief motivation in producing the Soundex name indexes was to assist citizens in finding census records to provide evidence of age, especially for those born before the advent of governmentally-approved birth certificates. (Verification of age was needed to establish eligibility for old-age benefits such as Social Security). Partial Soundex indexes of the 1930 census are available; resources from the Works Progress Administration were diverted towards support of World War II efforts before the project was completed. With the advent of computers, and more recently, the Internet, expanded indexes including all family members are beginning to appear on genealogy websites. These are accompanied with hypertext links that take the researcher directly to an image of the original census page, without having to travel to a regional library and scroll through endless rolls of microfilm. Genealogists view censuses as secondary sources of information; primary sources of information such as birth certificates are viewed as more reliable. Still, census information often provides useful information for genealogists and clues on where to proceed to find further primary source documents.

Local

In additional to the decennial federal census, more localized versions are often used. An example of this is Massachusetts, which takes a statewide census every fifth year. Likewise, each community in Massachusetts takes a municipal census each year. Category:Population

Population density

Population density is a measurement of population per unit area or unit volume. It is frequently applied to living organisms, humans in particular.

Biological population densities

Population density is a common biological measurement and is often used by conservationists as a more appropriate measure than absolute numbers. Low population densities may cause an extinction vortex, where low densities lead to further reduced fertility. This is referred to as the Allee effect, named after W. C. Allee, who first identified it. Examples of this may include:
- Increased problems with locating mates in areas of low density.
- Increased inbreeding in areas of low population density.
- Increased susceptibility to catastrophic events in low population densities. Different species will have different expected densities. For example R-selected species commonly have high population densities, while K-selected species may have lower population densities. Low population densities may be associated with specialised mate location adaptations such as specialised pollinators; as found in the orchid family (Orchidaceae).

Human population density

For humans, population density is the number of persons per unit of area (which may include or exclude inland water), though it may also be expressed in relation to habitable, inhabited, productive (or potentially productive) or cultivated area. Commonly this may be calculated for a county, city, country, another territory, or the entire world.
- In the country articles in Wikipedia, the density is typically based on land area. However, the list of countries by population density is based on total area, including inland water. Several of the highest-density territories in the world are very small city-states, micronations or dependencies. These territories share a relatively small area and an exceptionally high urbanization level, with an economically specialized city population drawing also on rural resources outside the area, illustrating the difference between high population density and overpopulation. The most densely populated large state is Bangladesh, where 134 million people live in a highly agricultural area around the lower Ganges river, with a national population density in excess of 900 persons per square kilometre. The Indonesian island of Java has a similar density, with 114 million people, resulting in about 856 people per square kilometre. Overall world population density presently averages 42 people per square kilometre. Cities with exceptionally high population densities are often considered to be overpopulated, though the extent to which this is the case depends on factors like quality of housing and infrastructure or access to resources. Most of the largest densely-populated cities are in southern and eastern Asia, though Cairo and Lagos in Africa also fall into the category. City population is however, heavily dependent on the definition used for the urban area: densities will be far higher for the central municipality than when more recently-developed and as yet administratively unincorporated suburbs are included, as in the concepts of agglomeration or metropolitan area, the latter including sometimes neighbouring cities.

Marriage

Marriage is a relationship between individuals which has formed the foundation of the family for most societies. Marriage can include legal, social, and religious elements. In western societies, marriage has traditionally been understood as social contract between a man (husband) and a woman (wife), while in other parts of the world polygamy has been the most common form of marriage, usually in the form of polygyny (a man taking several wives) but occasionally in the form of polyandry (a woman taking several husbands). In some western societies today, same-sex marriage is recognized yet remains a controversial issue.

Definitions

Precise definitions vary historically and between and within cultures: modern understanding emphasizes the legitimacy of sexual relations in marriage, yet the universal and unique attribute of marriage is the creation of affinal ties (in-laws). Traditionally, societies encourage one to marry "out" far enough to strengthen the ties, but "close" enough so that the in-laws are "one of us" or "our kind". One exception to this rule is found in the marriage of royalty, who strengthen their aid through concentration of wealth rather than through affinal ties. Even in this case, the individual was often encouraged to marry "within" close family limits. (Further discussion and reference: Marvin Harris, late, Professor of Anthropology, Columbia University) Marriage remains important as the socially sanctioned bond in a sexual relationship. Marriage is usually conceived as a male-female relationship designed to produce children and successfully socialize them. Historically, most societies have sanctioned polygamy. The West is a major exception. Europe and the United States were monogamous cultures. This was in part a Germanic cultural tradition, a requirement of Christianity (after the sixth century CE), and a mandate of Roman Law. However, Roman Law supported prostitution, concubinage, sex outside of marriage, homosexual sex, and sexual access to slaves. The Christian West formally banned these practices. Globally, most existing societies do not sanction polygamy as a form of marriage. For example, China shifted from allowing polygamy to supporting only monogamy in the 1953 Marriage act after the Communist revolution. Most African and Islamic societies continue to allow polygamy (around 2.0 billion people). This includes Indi
