The U.S. Census Bureau groups counties into CSAs and CBSAs primarily based on county population. We provide listings of both in combined_areas and corebased_areas.

For a detailed description, Wikipedia has excellent discussions of both areas: http://en.wikipedia.org/wiki/Combined_Statistical_Area and http://en.wikipedia.org/wiki/Core_Based_Statistical_Area. Also, the following map from Wikipedia is excellent to visualize the areas: http://upload.wikimedia.org/wikipedia/commons/7/7b/Combined_statistical_areas_of_the_United_States_and_Puerto_Rico.gif

NOTE: Not all counties are members of a CSA or CBSA.

The following details about FIPS Class Codes have been blatantly taken from the Census Bureau's website:

• H1. Identifies an active county or statistically equivalent entity that does not qualify under subclass C7 or H6.

• H4. Identifies a legally defined inactive or nonfunctioning county or statistically equivalent entity that does not qualify under subclass H6.

• H5. Identifies census areas in Alaska, a statistical county equivalent entity.

• H6. Identifies a county or statistically equivalent entity that is areally coextensive or governmentally consolidated with an incorporated place, part of an incorporated place, or a consolidated city.

• C7: Identifies an incorporated place that is an independent city; that is, it also serves as a county equivalent because it is not part of any county, and a minor civil division (MCD) equivalent because it is not part of any MCD.
