How to Request Access to the NLSY79, NLSY79 Young Adult, and NLSY97 Geocode Data
To protect the confidentiality of respondents, the Bureau of Labor Statistics restricts access to files that include variables on State, county, and metropolitan statistical area of birth and residence. These "Geocode" files are available only to researchers in the United States who agree in writing to adhere to the BLS confidentiality policy and whose projects further the mission of BLS to conduct sound, legitimate research in the social sciences. Applications from abroad cannot be accepted. Applicants must describe their research objectives and explain how the Geocode data are necessary to meet those objectives. Researchers who are granted access to NLSY Geocode files may use them at the facilities of their own institutions, provided that the facilities meet BLS security requirements. More. The NLSY Geocode application is available at www.bls.gov/nls/geocodeapp.htm.
How to Request Access to the NLSY Zip Code and Census Tract Files and the NLSY97 School Survey Data
The Bureau of Labor Statistics has opportunities available on a limited basis for researchers from colleges and universities, government, and eligible nonprofit organizations to obtain access to BLS data files not available on public-use or Geocode files. These confidential files are available for use only at the BLS National Office in Washington, DC, on statistical research projects approved by BLS. Access to data is subject to the availability of space and resources at BLS. More information can be found at How to Request Access to the NLSY Zip Code and Census tract files and the NLSY97 School Survey Data on the NLS Frequently Asked Questions page.
