NLSY79 Employer History Roster

NLSY79 Employer History Roster

The Employer History roster includes information on virtually all employers reported by NLSY79 respondents, with many of the employer characteristics reported for each employer included in a single record. These variables are classified as "XRND" variables, rather than being assigned to a single survey year. Data from 1979-2012 are currently available. The variables will be updated as necessary as revisions are made and with each progressive round.

Structure

In earlier years, the linking process required to build a record of various commonly used employer-specific characteristics that have been reported in different survey years has involved a rather complex process. Researchers would need to use variables indicating the employer number in the previous survey year and establish the link through each preceding year individually. Appendix 9: Linking Employers Through Survey Years details this process.

By contrast, the Employer History roster is designed to help alleviate that more involved process of employer linking for many of the most commonly used employer characteristics. The Employer History data is constructed in a roster structure, consisting of one record for each of the up to 57 jobs (so up to 57 records). Many employer characteristics have been compiled into each employer's record. The record for each employer will include each of the variables listed in the table below. For instance the record for employer #1 will contain EMPLOYERS_ALL_CPSJOB_[YEAR].01, EMPLOYERS_ALL_UNION_[YEAR].01, EMPLOYERS_ALL_IND_[YEAR].01, EMPLOYERS_ALL_OCC_[YEAR].01, etc. for each survey year that employer #1 was reported.

Data Notes

Employer information for additional employers (jobs 6-10) in some of the older survey years may not have been included in the roster. These jobs were often included on separate data tapes, the original data of which has been difficult to recover. Should any of these data on additional employers be recovered in the future, that data will be added to the Employer History roster accordingly and users notified of these additions. These employers comprise a very small proportion of those ever reported for a very small number of respondents.

Locating Employer History variables

The Employer History items can be easily located within the NLSY97 dataset on NLS Investigator by using one of the following search criteria:

  • Question Name (enter search term) index, "starts with", enter "EMPLOYERS_ALL" search term
  • Area of Interest (pick from list) index, "equals", choose areas of interest beginning with "EMPLOYERS_ALL"
  • Reference Number (enter search term), "starts with", enter "E"

Table 1 lists the contents of the Employer History roster. The variables are listed under the Areas of Interest currently assigned. The "variable names" column contains the qnames for each of the variables. Currently there are up to 57 jobs for each respondent included on the roster. This means that at least one respondent has reported 57 jobs over the course of the NLSY79's 25 rounds. Most respondents of course will have a much smaller number of jobs reported since 1979.
