Basics of Census Geography

There are several different types of geographic units of analysis that can be examined when using census data. There are methods for dividing up geography in the United States that most people are familiar with, such as by states, counties, and zip codes. In addition, the Census uses its own methods and terminology for geography, the most prevalent of which is a "Census tract," which divides up counties. The links on this page are provided to help users understand & collect Census geography data as well as comprehend how it can be utilized to better demonstrate population and demographic data.

The following image offers a basic outline of Census geographic divisions. For a full explanation of the diagram, see its description on American Factfinder.
