Stata, I guess the matter should rest there.
These are the FIPS codes. FIPS = "Federal Information Processing Standards". Details at <> and, in particular, <>. (Remember: "Google is your friend." (tm)) For anyone working with U.S. state data issued by U.S. gov't agencies, these are standard (hence the "S" in "FIPS") and common. And, yes, there are still only 50 U.S. states. There are, however, 51 FIPS codes between Alabama and Wyoming, inclusive: FIPS 11 is the District of Columbia, which (for those outside the U.S.) is not a state. Hence, -drop if fips == 11- is appropriate for many empirical applications. Since FIPS codes are standard, they can assist with -merge-s and other data management applications. HTH.
