Errata for NLSY97 Round 17 Release

Errata for NLSY97 Round 17 Release

NEWEST POSTED ERRATA

Duplicate Children and Erroneous Statuses Assigned on CV_CHILD Roster [posted 11/14/2019]

Some duplicate children were identified on the CV_CHILD roster in survey year 2015. These children have been deleted and other children moved up in position where necessary. In addition, a number of incorrect codes have been identified for the CV_CHILD_STATUS.## variables in survey years 2011, 2013 and 2015. These erroneous codes were the result of changes in questionnaire function for which adjustments were not fully made in the variable creation programs.

These corrections will be included in the next public data release, scheduled for December 2019. Update (12/6/2019): These corrections are now included on the public data release.

OTHER ERRATA

Missing Tax-Advantaged Account And Credit Card Debt Values For 2015 Respondents [posted 5/22/2019]

Calculations for the assets at age 30 and age 35 variables listed below inadvertently omitted values for tax-advantaged accounts for respondents reporting those assets in survey year 2015 (round 17). In addition, credit card balances for a small subset of respondents in survey year 2015 were not included in the debt or household net worth calculations at age 35. In connection with the missing credit card balances data, two lead-in questions were skipped in error for a small set of respondents. Variables affected for 2015 (round 17) are listed below.

Affected variables include:

Z91223.00  CVC_ASSETS_FINANCIAL_30  FINANCIAL ASSETS AT AGE 30 
Z91219.00 CVC_HH_NET_WORTH_30 NET WORTH OF HOUSEHOLD AT AGE 30
Z91418.00 CVC_ASSETS_FINANCIAL_35 FINANCIAL ASSETS AT AGE 35 
Z91420.00 CVC_ASSETS_DEBTS_35 DEBT AT AGE 35 
Z91414.00   CVC_HH_NET_WORTH_35 NET WORTH OF HOUSEHOLD AT AGE 35
U10015.00 YAST35-5210A DOES R/SPOUSE/PARTNER HAVE ANY CREDIT CARDS?
U10016.00  YAST35-5210AA DOES R/SPOUSE/PARTNER PAY OFF CREDIT CARD BALANCES IN FULL?

Corrections for these errors will be included in the next public data release. Update (12/6/2019): These corrections have now been made on the public data release.

Problem in Pregnancy Series for Female Respondents in Round 17 (2015) [posted on 4/17/2018]

In the round 17 data, due to an error in the preloaded data, the majority of female respondents answered a complete retrospective series on pregnancies, rather than on pregnancies since the date of last interview. This is the reason for the large frequency number in question YSAQ2-314 (2590 responses) and the low frequency number for question YSAQ2-314C (980 responses). This error also affects the pregnancy outcome frequencies in YSAQ2-326, YSAQ2-326D, and YSAQ2-326F.

Case Data Deletion [posted on 4/9/2018]

After the release of the 2013 data, the case data for respondent id 1061 were determined to be invalid for that survey year. The 2013 data for id 1061 have been removed from the round 17 release data, and the status of this case for survey year 2013 has been set to a non-interview.

NLSY97 Schooling Event History Errata [posted on 3/1/2018]

Researchers comparing the latest round of the schooling event history variables with previous rounds of data will notice some historical data has changed. In general, some cases in the historical schooling data are modified each round since the NLSY97 first released the schooling event histories.

The histories get modified for a number of reasons. First, the overall schooling event histories are created by laying down an early round of information, then overlaying any changes on top. The program that creates the histories first puts down round 2’s information. Then the program layers round 3’s information on top. When this is done, round 4’s information is then layered over all the previous sets of data and the process repeats until the current round. Because respondents are allowed to provide information about schooling that is not constrained by the date of the last interview, some respondents provide changes and additions that modify earlier historic data that has been released to the public.

For example, public ID 1129 provided information that changes the values in the SCH_COLLEGE_TERM array between round 16 and 17. The SCH_COLLEGE_TERM array shows which schools and what semesters or terms the respondent is attending. This respondent in round 16 reported going to two different schools. For the second school they attended they reported going to six different semesters or terms. In round 17 they came back and reported different term dates for attending the second school. In the schooling event histories, newer information is assumed more complete and correct. Because they provided newer information, these new data over-wrote the older information and changed the historical values.

Another reason why historical schooling data can change is because the NLSY97 does not ask about full- or part-time status until after a term is marked as completed. This means there are some respondents who start schooling but their full- or part-time status is unknown until later. These changes show up in the SCH_COLLEGE_DEGREE arrays.

For example, in round 16 the historical data for respondent ID 3317 had a missing code (flagged as a 303) in 2001 to 2004. In round 17 the questionnaire determined that all the schooling in these years was done as part of a full-time program (coded as 103). The historical data from 2001 to 2004 were all changed from a code of 303 to 103 to reflect this new information, which was acquired in 2017.
