U.S. Census data
Data from the United States Census Bureau are released as individual files for the 50 states, the District of Columbia and Puerto Rico. Observations are generated from questions to subjects/housing units, covering demographic, social, economic and other characteristics. Coverage is for the USA and its regions, divisions, states, counties, metropolitan areas, American Indian and Alaska Native areas, Hawaiian homelands and congressional districts.
The census is conducted every ten years. The Census Bureau provides an overview of decennial census collection and collation methodology from 1790 to 2010.
Details of methodology are available on the U.S. Census Bureau site.
