The U.S. Census Bureau has conducted the Decennial Census every 10 years since 1790. It provides a full count of the U.S. population for congressional and legislative redistricting and includes detailed demographic information spanning over 220 years. Starting in 2010, the Census stopped using the long form survey and now reports information on population, households, age, sex, race and ethnicity, and housing characteristics only. For the latest detailed demographic and socioeconomic data, please use the American Community Survey.<br><br>U.S. Decennial Censuses on 2010 Geographies provide reallocated data from Decennial Censuses on 2010 geographies. Reallocation of decennial census data on 2010 geographies was performed using reallocation fractions from Longitudinal Tract Data Base (LTDB). Data is available on census tract, county, state and nation level geographies. The form of this survey, as well as the datasets and tables it contains, is kept similar to our corresponding Decennial Census surveys. U.S. Decennial Census is a category of data layers within the Social Explorer application. To find individual datasets, log in to Social Explorer, select a category, and browse to the desired layer.
