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 all of us, but gather different types of information about all of us.
The censuses put this collected data in a convenient place! Until the 1990 Census, the data was all in print. Now, the library has 4 of the last censuses on CD-ROM. They 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.
All of the United States census data are shelved in one place in the library collection. They are all located with other print goverment documents in the United States Government Documents on Baker Level 1. The area shown as "Stacks" is where the government documents are.
Just about every subject can use Census data. The following are the subjects that are directly related to Census data collection.
