Census 2010 is the most recent decennial census, which generates population counts by age, sex, race/ethnicity, for people living in households and group quarters, as well as counts of housing units, both occupied and vacant.
The decennial (every 10 year) U.S. Census aims to count every resident in the United States. It is mandated by Article I, Section 2 of the U.S. Constitution and has been taking place since 1790. The data collected by the decennial census determine the number of seats each state has in the U.S. House of Representatives and is also used to direct the distribution of federal funds. The results of each decennial census are also used by states for redistricting. Redistricting is when state officials realign congressional and state legislative districts, taking into account population shifts since the last census and assuring equal representation for their constituents.
Users should note that the 2000 decennial census was the last recent census that contained both a short form (given to all of the population) and a long form (given to just a sample, or portion, of the population). Historically, the long form generated the data regarding detailed social, economic and housing characteristics. However, these data are now collected by the ongoing American Community Survey and were not asked in the 2010 decennial census. Learn more about the American Community Survey (ACS). ACS data are featured in various places in our Data By Topic section.
