The Nineteenth United States Census , conducted by the Census Bureau, determined the resident population of the United States to be 203,392,031, an increase of 13.4 percent over the 179,323,175 persons enumerated during the 1960 Census. This was the first census since 1800 in which New York was not the most populous state – California overtook it in population in November 1962. This was also the first census in which all states recorded a population of over 300,000, and the first in which a city in the geographic South recorded a population of over 1 million (Houston).

United States Census Decennial census mandated by Article I, Section 2 of the United States Constitution

The United States Census is a decennial census mandated by Article I, Section 2 of the United States Constitution, which states: “Representatives and direct Taxes shall be apportioned among the several States... according to their respective Numbers.... The actual Enumeration shall be made within three years after the first meeting of the Congress of the United States, and within every subsequent Term of ten Years”. Section 2 of the 14th Amendment amended Article I, Section 2 to include that the "respective Numbers" of the "several States" will be determined by "counting the whole number of persons in each State... excluding Indians not taxed...” The United States Census Bureau is responsible for the United States Census. The Bureau of the Census is part of the United States Department of Commerce.

United States Census Bureau Bureau of the United States responsible for the census and related statistics

The United States Census Bureau is a principal agency of the U.S. Federal Statistical System, responsible for producing data about the American people and economy. The Census Bureau is part of the U.S. Department of Commerce and its director is appointed by the President of the United States.

An enumeration is a complete, ordered listing of all the items in a collection. The term is commonly used in mathematics and computer science to refer to a listing of all of the elements of a set. The precise requirements for an enumeration depend on the discipline of study and the context of a given problem.

Data availability

Microdata from the 1970 census are freely available through the Integrated Public Use Microdata Series. Aggregate data for small areas, together with electronic boundary files, can be downloaded from the National Historical Geographic Information System. These data were originally created and disseminated by DUALabs. Personally identifiable information will be available in 2042. [1]

In the study of survey and census data, microdata is information at the level of individual respondents. For instance, a national census might collect age, home address, educational level, employment status, and many other variables, recorded separately for every person who responds; this is microdata.

In statistics, aggregate data are data combined from several measurements. When data is aggregated, groups of observations are replaced with summary statistics based on those observations.

The National Historical Geographic Information System (NHGIS) is a historical GIS project to create and freely disseminate a database incorporating all available aggregate census information for the United States between 1790 and 2010. The project has created one of the largest collections in the world of statistical census information, much of which was not previously available to the research community because of legacy data formats and differences between metadata formats. The statistical and geographic data are disseminated free of charge through a sophisticated online data access system.

The American Community Survey (ACS) is an ongoing survey by the U.S. Census Bureau.

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.
