Decennial Census 2020
Every ten years, the Census Bureau conducts a constitutionally-mandated national household survey to count every resident in the United States. 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.
