Created residence variables - Rounds 2-10

A small change in the program recoded invalid skips (-3) values in rounds 2 through 10 to valid skips (-4); this reflects the original program done in round 1. A small change specific to the round 5 data updated this variable to reflect refusals (-1) and don't know answers (-2) in YHHI-3500 to invalid skips (-3). The variables and number of affected respondents are below:

  • Round 2: CV_TTL_RESIDENCES - 951
  • Round 3: CV_TTL_RESIDENCES - 909
  • Round 4: CV_TTL_RESIDENCES - 896
  • Round 5: CV_TTL_RESIDENCES - 896
  • Round 6: CV_TTL_RESIDENCES - 888
  • Round 7: CV_TTL_RESIDENCES - 847
  • Round 8: CV_TTL_RESIDENCES - 834
  • Round 9: CV_TTL_RESIDENCES - 808
  • Round 10: CV_TTL_RESIDENCES - 838

Created MSA variable - Round 10 

40 respondents were changed from a valid skip (-4) to a code of out of the country (5) in the round 10 CV_MSA variable.

Created income variables - Rounds 8-10

A small change in the income and poverty program was required to capture a questionnaire change beginning in round 8. The variables and number of affected respondents are below:

  • Round 8:
    CV_HH_POV_RATIO - 473
    CV_INCOME_FAMILY - 473
  • Round 9:
    CV_HH_POV_RATIO - 446
    CV_INCOME_FAMILY - 444
  • Round 10:
    CV_HH_POV_RATIO - 413
    CV_INCOME_FAMILY - 414

Additional notes

The CVC_RND_2005 variable was inadvertently omitted from the round 9 data release. This variable indicates the respondent's most recent interview round regardless of their round 9 interview status. It should be used in conjunction with the CVC_* variables to determine which round from which the information was collected.

The military pay variables for rounds 8 and 9 were inadvertently omitted from the latest NLSY97 release. These variables will be included in the next full release of NLSY97 data.

Omitted from the Round 4 Codebook Supplement is the documentation of the program creating the Round 4 ESR and collapsed ESR variables (CV_ESR, R55289.00 and CV_ESR_COLLAPSED, R55290.00).

Round 1 through round 6 PIAT variables that detail the test answers and conditions will be included in the next full release of NLSY97 data.
