The territories are scattered about the Pacific Ocean and the Caribbean Sea. At 3.8 million square miles (9.842 million km²) and with over 320 million people, the country is the world's third or fourth-largest by total area and the third most populous. It is one of the world's most ethnically diverse and multicultural nations, the product of large-scale immigration from many countries.

Historical

SS United States

SS United States is a luxury passenger liner built in 1952 for United States Lines designed to capture the trans-Atlantic speed record.

Built at a cost of $79.4 million ($724 million in today's dollars) the ship is the largest ocean liner constructed entirely in the U.S. and the fastest ocean liner to cross the Atlantic in either direction. Even in her retirement, she retains the Blue Riband, the accolade given to the passenger liner crossing the Atlantic Ocean in regular service with the highest speed.

Her construction was subsidized by the U.S. government, since she was designed to allow conversion to a troopship should the need arise.United States operated uninterrupted in transatlantic passenger service until 1969. Since 1996 she has been docked at Pier 82 on the Delaware River in Philadelphia.

Design and construction

Inspired by the exemplary service of the British liners RMS Queen Mary and Queen Elizabeth, which transported hundreds of thousands of U.S. troops to Europe during World War II, the U.S. government sponsored the construction of a large and fast merchant vessel that would be capable of transporting large numbers of soldiers. Designed by renowned American naval architect and marine engineer William Francis Gibbs (1886–1967), the liner's construction was a joint effort between the United States Navy and United States Lines. The U.S. government underwrote $50 million of the $78 million construction cost, with the ship's operators, United States Lines, contributing the remaining $28 million. In exchange, the ship was designed to be easily converted in times of war to a troopship with a capacity of 15,000 troops, or to a hospital ship .

1940 United States Census

The Sixteenth United States Census, conducted by the Census Bureau, determined the resident population of the United States to be 132,164,569, an increase of 7.3 percent over the 1930 population of 123,202,624 persons. The census date of record was April 1, 1940. A number of new questions were asked including where people were 5 years before, highest educational grade achieved, and information about wages. This census introduced sampling techniques; one in 20 people were asked additional questions on the census form. Other innovations included a field test of the census in 1939.

Personally identifiable information will be available in 2022.

1810 United States Census

The United States Census of 1810 was the third Census conducted in the United States. It was conducted on August 6, 1810. It showed that 7,239,881 people were living in the United States, of which 1,191,362 were slaves.

The 1810 Census included one new state: Ohio. The original census returns for the District of Columbia, Georgia, Mississippi, New Jersey, and Ohio were lost or destroyed over the years. Most of Tennessee's original forms were also lost, other than Grainger and Rutherford counties.

Questions

The 1810 Census form contained the following information (identical to the 1800 census):

1840 United States Census

The United States Census of 1840 was the sixth census of the United States. Conducted by the Census Office on June 1, 1840, it determined the resident population of the United States to be 17,069,453 — an increase of 32.7 percent over the 12,866,020 persons enumerated during the 1830 Census. The total population included 2,487,355 slaves. In 1840, the center of population was about 260 miles (418 km) west of Washington, near Weston, Virginia.

Controversy over statistics for mental illness among Northern blacks

The 1840 Census was the first that attempted to count Americans who were "insane" or "idiotic". Published results of the census indicated that alarming numbers of black persons living in non-slaveholding States were mentally ill, in striking contrast to the corresponding figures for slaveholding States.

Pro-slavery advocates trumpeted the results as evidence of the beneficial effects of slavery, and the probable consequences of emancipation. Anti-slavery advocates contended, on the contrary, that the published returns were riddled with errors, as detailed in an 1844 report by Edward Jarvis of Massachusetts in the American Journal of the Medical Sciences, later published separately as a pamphlet, and in a memorial from the American Statistical Association to Congress, praying that measures be taken to correct the errors.
