Decennial Census 2010

Every ten years through 2000, the Census Bureau conducted a national household survey. The federal government uses Decennial Census data for apportioning congressional seats, for identifying distressed areas, and for many other activities. Beginning with the 2010 Census, the Census Bureau included only the short form (the long form was replaced by the ACS). Short form information is collected on every person and includes basic characteristics, such as age, sex, and race.
