U.S. Decennial Census: Population and Housing Counts for Representation and Planning
Overview of the U.S. decennial census: how the Census Bureau collects population and housing counts and how those data shape congressional apportionment, redistricting, government funding, planning, and research.
United States Census refers to the nationwide population count that the federal government carries out every ten years. The U.S. Constitution requires this decennial enumeration, conducted in years ending in “0,” and it has been performed since 1790. The census is a form of census specific to the United States and provides the baseline data used for many civic and budgetary decisions.

6 ImagesWhat the count measures
The process consists of two principal components taken at the same time: a census of people (the population count) and a census of housing. The population count has been collected since 1790; the housing count, which records numbers of residential housing units, has been included since 1940. Together these datasets inform demographic statistics, trends, and official totals.
Primary uses
- Apportionment: census results determine how many seats each state receives in the House of Representatives, and they are the starting point for state-level redistricting.
- Funding and planning: federal and state agencies use census figures to guide the distribution of many types of government resources and to plan services and infrastructure.
- Research and policy: population and housing data support academic research, business planning, and public policy development.
Administration and history
Responsibility for organizing and carrying out the census falls to the United States Census Bureau, a federal agency that manages questionnaire design, data collection, processing, and the release of aggregate statistics. The first post‑Revolution federal enumeration was taken in 1790; at that time the task was overseen by the Secretary of State, Thomas Jefferson, who helped arrange the initial count.
Over more than two centuries the census has evolved in methods and scope, but its core purpose—providing an accurate, periodic count of the population and housing for representation and public administration—remains unchanged.
