NLSY97

This attachment provides 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. 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.

• Migration Distance Variables
• Parent Distance Variables

Respondent Migration Variables

During the interview, respondents report the name and location of each college they have attended. Information from the Integrated Postsecondary Education Data System (IPEDS) is then merged with the name and address of the youth's college to provide users with a code identifying the school (GEO69) and its location (GEO70). 

The NLSY97 geocode file contains detailed information on the geographic residence of each NLSY97 respondent. These data permit researchers to analyze the influences that a respondent's area of residence or type of environment may have on outcomes such as education and employment.

To complement data on respondents' educational experiences collected during the yearly interviews, NLSY97 staff collected transcripts directly from respondents' high schools once the youths graduated or left school. Once the transcripts were received from the schools, survey staff coded the transcript record into a standard format. The resulting created variables comprise a history of the respondent's terms in school, courses taken, and other academic indicators.
