Demographic data is collected from the Census and the American Community Survey. The decennial census occurs every 10 years, in the years ending in "0," to count the population and housing units for the entire United States. Its primary purpose is to provide the population counts that determine how seats in the U.S. House of Representatives are apportioned. Census figures also are required to draw congressional and state legislative district boundaries, to allocate federal and state funds, to formulate public policy, and to assist with planning and decision-making in the private sector. The decennial census provides detailed information on:
- Population
- Age
- Sex
- Race and ethnicity
- Housing
- Household characteristics and relationships
- Education
- Geographic Mobility
