2010 Census data is now available via the new American Factfinder website (see below).
Statistics collected by the Census help gather information to build and increase resources for your community. Data collected from the Census provides quick as well as detailed facts about the population of the U.S.
Questions change from Census to Census (sometimes dramatically) which means that the statistics available change from decade to decade. The easiest way to find out what information is available for a specific Census is to look at the Census questionnaires. If the question wasn’t asked, the information isn’t available. It’s that simple. For copies of the original Census Questionnaires since 1790, see the Census publication Measuring America: The Decennial Censuses from 1790 to 2000
