Errata and Updates for NLSY97 Round 13 Release

National Longitudinal Survey of Youth - 1997 Cohort

Errata and Updates for NLSY97 Round 13 Release

Inconsistencies Found in NEWSCHOOL Roster & Event History Variables

NLSY97 staff have recently discovered a problem which affects the NEWSCHOOL_INTERVIEW.xx and NEWSCHOOL_PUBID.xx variables in many rounds of the NLSY97 data. These variables are intended, respectively, to identify the round in which a particular school is first reported and then to assign a permanent public ID to the school within each respondent's enrollment history. This allows users to determine whether a respondent is enrolled at a school that was first reported in an earlier round, or whether a respondent has enrolled in a new school. For approximately 550 respondents, we have discovered that some colleges which appear to be newly reported colleges are in fact schools that were originally reported in an earlier round. This problem appears to have affected only colleges and is much more prevalent in the more recent rounds of data collection. These corrections will also affect the created event history array based on the college attended SCH_COLLEGE_ID_year.xx. These data will be corrected in the next release of the NLSY97 data which is scheduled for September 2012.

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 by clicking here for a PDF file.

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.

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.
