Recent Corrections and Changes to the NLSY97 data

1) Dropped cases and sampling weight variables - Round 13

All data for cases 8342 and 8343 in round 13 have been deleted, as interviewers discovered that the wrong persons had been interviewed in that round. As a result, the sampling weight variables for round 13 have been recomputed and are available in the following zip file: r13weights

2) Applicable Weights for ASVAB_MATH_VERBAL_SCORE_PCT (R98296.00)

This set of weights is for the 7,093 respondents with a score on ASVAB_MATH_VERBAL_SCORE_PCT (R98296.00). The first column of the text file is the public use ID, followed by a space delimiter. The second column on each line is the weight, with two implied decimal points. The balance of respondents without a valid ASVAB_MATH_VERBAL_SCORE_PCT score should be given a missing or zero weight, depending on your statistical program. Users can access data for these variables in the following zip file: NLSY97ASVAB_MATH_VERBALweights.dat

Warning, public id 8950. This non-black/non-Hispanic 12 year old female is from the supplemental sample. This individual represents 18,967 people, whereas the respondent with next highest representation accounts for 7,003 people. However, on ASVAB_MATH_VERBAL_SCORE_PCT this respondent is of average intelligence and falls in the mid-point of the distribution so they will not exert a huge influence on result

3) Created relationship of the respondent to parent figures/guardians (CV_YTH_REL_HH_CURRENT)

A small error in the round 2 created variable program caused 12 respondents to have the incorrect relationship specified in this variable. The correct relationship and the corresponding respondent pubid is listed below:

pubid	CV_YTH_REL_HH_CURRENT
225	10
2560	10
2860	10
3298	10
4352	10
4901	10
5750	10
6481	10
7414	10
7634	10
7638	10
8505	10

These will be updated in the next release.

4) Month and year selected household members first started living with the respondent variables

The following variables, which collect the month and year selected household members first started living with the respondent, have been unintentionally omitted from previous NLSY97 data releases. These variables represent data collected in question YHHI-51680, found in NLSY97 questionnaire rounds two through six. Please click here to access the zip file that contains these variables.

These variables will be included in all future NLSY97 data releases.

5) Recently created variables that represent the unique ids for all freelance jobs reported in NLSY97 rounds 1 and 2

The following variables have been recently created and will be added to future NLSY97 data releases. These variables represent the unique ids for all freelance jobs reported in NLSY97 rounds 1 and 2 and can be used to track those jobs in rounds 3 through 5.

Please click here to access the zip file that contains these variables for round 1:

6) Created Marriage variables (CV_MARSTAT, CV_MARSTAT_COLLAPSED, MAR_STATUS, MAR_PARTNER_LINK)

After a review of the marriage data, a few inconsistencies were found and will be corrected on the round 14 release.

Due to the respondents reporting inconsistent dates in different rounds, the following edits need to be made:

Corrections to the NLSY97 Technical Sampling Report

The numbers in the last two columns (DEFF and DEFT) of tables 5.37-5.48 were incorrect (Table 5.49, which summarizes these tables, was also incorrect) in the NLSY97 Technical Sampling Report. These tables have been corrected, and the whole Section (Section 5.5) containing these tables can be downloaded and replaced in the NLSY97 Technical Sampling Report.
