Variables Created

• CV_YTH_REL_HH_AGE_2
• CV_YTH_REL_HH_AGE_6
• CV_YTH_REL_HH_AGE_12

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.

These variables were only created in Round 1.

Variables Created

• CV_MARSTAT (marstat)--marital status as of interview date (10 categories coded)
• CV_MARSTAT_COLLAPSED (cmarstat)--marital status as of interview date (5 categories coded)
• CVC_FIRST_COHAB_DATE~M (cohm), CV_FIRST_COHAB_DATE~Y (cohy)--date of first cohabitation
• CVC_FIRST_MARRY_DATE~M (marm), CV_FIRST_MARRY_DATE~Y (mary)--date of first marriage
• CVC_FIRST_COHAB_MONTH (cohcm)--date of first cohabitation in continuous month format

• CVC_TRN_CERT_DATE~M, Y (TRNCMTH, TRNCYR)
