How can I find Census data?

You can find Census data in our Census Comparison interactive tool. Since small Census geographies (such as tracts and block groups) can change over time, it’s sometimes difficult to compare these changes at these levels.  With D3's Census Comparison tool, the heavy lifting has been done for you! We've aggregated the information in a way that allows you to make 'apples-to-apples' comparison -- even in Census tracts that changed between 2000 and 2010! The Census Bureau also releases data from several other sources that are not fully integrated into our online toolbox.  These include the American Community Survey (see below), American Fact Finder, and the bi-annual Planning Database. If you’re seeking historical data (from 1990 or earlier), please refer to the historical counts data from the Census Bureau, the Bureau’s FTP site, or your local library.  A partner organization in Minnesota, the Minnesota Population Center, also maintains the National Historical Geographic Information System (NHGIS), which assembles census data and boundary files for the entire country from 1790 to 2013.
