Geographic Areas Used by the Census Bureau

The Census Bureau defines many different geographic areas which can be used to organize and aggregate data. The areas the Census Bureau uses can be divided into those which are legally defined and those which are not. The Census Bureau refers to non-legally defined areas as statistical areas.
