Accessing Data / Cohorts

It is recommended that users build custom data sets for their particular research instead of downloading entire sets due to the extraordinarily large amount of NLS data. Users may access custom sets via the Investigator, the NLS online search and extraction tool.

For users who have the capacity to utilize extremely large data files and the programs to handle them, downloads are available for NLSY97, NLSY79, NLSCYA and the original cohorts: Mature Women, Young Women, Older Men, and Young Men.

Each download file includes a data file (.dat); a codebook file (.cdb); programs to read the data into SAS (.sas), SPSS (.sps), and R (.R); and a tagset file listing all reference numbers (.COHORT NAME). Stata programs are available through Investigator but are not included here because the full data sets are too large to open in Stata.
