The following pages provide coding information for the state and county variables included on the NLSY97 geocode CD.  These variables use the current Federal Information Processing Standards (FIPS) codes.  This attachment is organized as follows:  Table 1 provides the state codes for the 50 states and Washington, D.C., and Table 2 lists the codes used for outlying areas and territories of the United States.  Although no respondents have lived in an outlying area to date, this table is provided in anticipation that the codes will be needed at some point in the future.  Finally, the subsequent pages list the counties (and independent cities, if applicable) of each individual state with their assigned codes.

For Rounds 1-7, these variables used the 1990 Census codes. Beginning in Round 8, the 2000 codes were used. There are very few changes between the two systems. This attachment presents the 2000 codes, and it also notes changes from the 1990 system where appropriate.
