Relationship to Household Parent Figures (Round 1 Parent Interview) - Appendix 3

National Longitudinal Survey of Youth - 1997 Cohort

Relationship to Household Parent Figures (Round 1 Parent Interview) - Appendix 3

Variables Created


This program creates variables indicating the relationship of the youth to the primary adults in the household when the youth was age 2, 6, and 12. Note that this program uses data from the Round 1 Parent Questionnaire, so it is only available for respondents who have a completed parent interview.
