population from 2010 Census
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:

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.
