Every 10 years, the United States government is required to count all of its citizens. This is called the Decenniel Census. The government not only tries to count us, but gather other information about us too.
The Census Bureau put some of this collected data in one convenient place! You can use American FactFinder 2 to download data from the 2000 and 2010 censuses. For earlier censuses, there are several online sources from which to choose. The library also has the data of several censuses on CD or DVD. The CDs/DVDs are housed in the Evans Map Room. You can pick your geography, which is dependent on the year, pick the variables you want to see and create a database, a map or both.
Just about every subject can use Census data. The following are the subjects that are directly related to Census data collection.
