U.S. Census Demographic Data: Overview

A guide to finding and using population data from the U.S. Census Bureau

Navigating the Census

Every ten years, the U.S. Census Bureau aims to count every resident in the United States and Puerto Rico, and makes that data available free of charge as the Decennial Census. Since the 2010 Census, socioeconomic and housing data is provided by the American Community Survey, which is available in yearly updates for some areas of the country.

For current (2010) population counts by race, age or sex: See 2010 Census
For current income, education or other social data: See American Community Survey
For data from 2000 and before: See Historical Census
For original census schedules, or custom tabulations: See Manuscript & Microdata
To make a map from census data: See Mapping the Census
