The U.S. Census Bureau collects data about the social, physical and economic conditions of the population, including information about race, education, family, employment status and housing status. The Census Bureau releases a full description of the gathered data from the most recent census, and the data themselves on its website.
The U.S. Census Bureau releases data in a variety of formats, including tables, which are posted at FactFinder.Census.gov, and maps, available at Census.gov. Census.gov includes data from previous censuses as well. The Census Bureau additionally performs the American Community Survey in order to gather more up-to-date data, based on smaller sample sizes, and with larger margins of error, than the 2000 U.S. Census.
Race data in the census summary file include population counts for 63 race categories. Employment information gathered include income status and benefits, employment sector and commuting habits. Housing data include housing tenure (rented or owned) by age, household type, and race origin of householder, and mortgage status of owned housing units. Education data include schooling status of children living in the household and educational attainment of heads of household. Social information gathered includes languages spoken, marital status, disability status, and computer and Internet use. Age data are gathered in five-year increments.
