The United States census of 1940, 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 122,775,046 people. The census date of record was April 1, 1940. A number of new questions were asked including where people were five 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. This was the first census in which every state (48) had a population greater than 100,000.
The 1940 census collected the following information:
In addition, a sample of individuals were asked additional questions covering age at first marriage, fertility, and other topics. Full documentation on the 1940 census, including census forms and a procedural history, is available from the Integrated Public Use Microdata Series.
Following completion of the census, the original enumeration sheets were microfilmed; after which the original sheets were destroyed.
As required by Title 13 of the U.S. Code, access to personally identifiable information from census records was restricted for 72 years.Non-personally identifiable information Microdata from the 1940 census is freely available through the Integrated Public Use Microdata Series. Also, aggregate data for small areas, together with electronic boundary files, can be downloaded from the National Historical Geographic Information System.
On April 2, 2012—72 years after the census was taken—microfilmed images of the 1940 census enumeration sheets were released to the public by the National Archives and Records Administration. The records are indexed only by enumeration district upon initial release; several organizations are compiling indices, in some cases through crowdsourcing.

During World War II, the Census Bureau responded to numerous information requests from US government agencies, including the US Army and the US Secret Service, to facilitate the internment of Japanese Americans. In his report of the operation, U.S. Army Lt. Gen. John L. DeWitt wrote that "The most important single source of information prior to the evacuation was the 1940 Census of Population."
The National Archives and Records Administration (NARA) is an independent agency of the United States government charged with the preservation and documentation of government and historical records. It is also tasked with increasing public access to those documents which make up the National Archive. NARA is officially responsible for maintaining and publishing the legally authentic and authoritative copies of acts of Congress, presidential directives, and federal regulations. NARA also transmits votes of the Electoral College to Congress. It also examines Electoral College and Constitutional amendment ratification documents for prima facie legal sufficiency and an authenticating signature.

The United States census is a census that is legally mandated by the U.S. Constitution, and takes place every 10 years. The first census after the American Revolution was taken in 1790, under Secretary of State Thomas Jefferson; there have been 23 federal censuses since that time.
The American Community Survey (ACS) is a demographics survey program conducted by the U.S. Census Bureau. It regularly gathers information previously contained only in the long form of the decennial census, such as ancestry, citizenship, educational attainment, income, language proficiency, migration, disability, employment, and housing characteristics. These data are used by many public-sector, private-sector, and not-for-profit stakeholders to allocate funding, track shifting demographics, plan for emergencies, and learn about local communities. Sent to approximately 295,000 addresses monthly, it is the largest household survey that the Census Bureau administers.
The United States census of 2010 was the twenty-third United States national census. National Census Day, the reference day used for the census, was April 1, 2010. The census was taken via mail-in citizen self-reporting, with enumerators serving to spot-check randomly selected neighborhoods and communities. As part of a drive to increase the count's accuracy, 635,000 temporary enumerators were hired. The population of the United States was counted as 308,745,538, a 9.7% increase from the 2000 census. This was the first census in which all states recorded a population of over half a million people as well as the first in which all 100 largest cities recorded populations of over 200,000.

The census also saw Chicago rise in rank to the nation's second most populous city, a position it would hold until Los Angeles would supplant it in 1990. This was the first U.S. census to use machines to tabulate the collected data.

The total population was 38,925,598 with a resident population of 38,558,371 individuals, a 22.6% increase from 1860.
