About the Program

This webpage provides information on the Bureau of Labor Statistics (BLS) onsite researcher program. The onsite program allows access to confidential microdata to eligible researchers for approved statistical analysis. Researchers are encouraged to apply for access as early as possible.

Federal employees and contractors of the Federal government seeking access to confidential BLS data for statistical analysis should contact as a different application process applies. Researchers are encouraged to discuss their projects with the appropriate BLS contacts prior to submitting an application to the BLS. This program allows approved researchers workspace at the BLS national office in Washington, D.C., where all work with confidential data must take place. The application procedures outlined on this webpage apply to onsite research only.

Available Data

The BLS strives to make available to the public the maximum amount of information possible without compromising the confidentiality pledged to survey respondents. The BLS is legally bound to protect from disclosure individually identifiable data collected for exclusively statistical purposes under a pledge of confidentiality. Please see the Confidential Information Protection and Statistical Efficiency Act (PDF) for more information. Depending on the data involved, other laws, such as the Privacy Act, the Trades Secret Act, and the Workforce Investment Act, also may be applicable.

Due to such confidentiality constraints, publicly available data sometimes are insufficient to meet researcher needs. The BLS has opportunities available on a limited basis (1) for researchers to access confidential data for purposes of conducting valid statistical analyses. Eligible researchers may apply for access to confidential data from the following surveys and administrative databases.

Data Available For Onsite Research

Data on employment and unemployment:

Data on prices and living conditions: (1)

Data on compensation and working conditions:

Data Available For Offsite Research
Please note that the application procedures outlined on this webpage are for onsite data access only. Different application procedures apply to offsite access. 

Who Can Apply?

Researchers may be eligible to access confidential BLS data files for statistical research if they meet certain qualifications. To qualify, you must satisfy the following two requirements: 

  • Either be a citizen of the United States, or be a citizen of an eligible country as determined by the State Department. Non-citizens must contact the BLS at to determine their eligibility prior to submitting an application as other complications may be a factor. Applications received from non-citizens may take significantly longer to process.
  • Either be enrolled as a student at least half time in an eligible educational institution, or be employed by one of the following organizations (4):
    • An institution of higher education
    • An eligible nonprofit organization (IRS 501c(1) or 501c(3) organizations)
    • A State, local, or Indian tribal government
    • An association of State or local public officials
    • An organization representing member State or local governments
    • A Federally funded research and development center

Confidential BLS data are available for research that is exclusively statistical, with appropriate controls to protect the data from unauthorized disclosure. Researchers granted access will be responsible for adhering to the confidentiality policies of BLS.  

Once an application is approved, the researcher and his or her employer or educational institution must enter into a written legal agreement with the BLS. The terms and conditions of such agreements are non-negotiable. Contact the BLS at to obtain a sample agreement.  

Researchers coming to the BLS to perform statistical research will not be compensated by the BLS for their work or any associated expenses, such as traveling or living expenses. 

Researchers will be subject to a security background check, known as the National Agency Check with Inquiries (NACI).

Research Proposal Guidelines

Applicants are encouraged to contact the BLS to determine the availability of data and the feasibility of their project prior to submitting proposals. Research projects must meet the following four criteria: 

  • Be exclusively statistical in nature  
  • Have technical merit  
  • Be of significant interest to the BLS  
  • Further the mission of the BLS 

Research proposals should be between 5 and 10 pages. They should include the following information:  

  1. An abstract summarizing the hypothesis to be tested, the data set involved, relevant variables, the empirical methods to be used, and the data outputs that will result from the project. (The abstract should be no longer than 300 words.)  

  2. A literature review including brief discussion of how the proposed research contributes to the existing body of research  

  3. The hypothesis that will be tested  

  4. The data set and variables that will be used in the analysis 

  5. The empirical methods that will be used  

  6. The specific data outputs that will result from the project, including a description of whether the research results will be presented as descriptive statistics or frequencies, or via multivariate analysis such as regression coefficients  

  7. An explanation of why the research requires use of non-public data   

  8. An explanation of why the research is of interest to the BLS and how it furthers the agency’s mission

In addition to the research proposal, applications should include the following information:  

  1. A description of how the research will be presented, such as in a doctoral dissertation, journal article, or book  

  2. The source of funding for the project (if any)  

  3. A statement as to whether the work will be conducted in collaboration with researchers from other organizations  

  4. A timeline detailing access dates at the BLS, the frequency and duration of visits, and an estimate of the total length of time needed to complete the project. (All projects are of limited duration, with a maximum time period of two years. At the end of the project, researchers may submit written proposals for an extension of time in which to access the data. If resources are available, access may be granted for an additional time not to exceed an additional two years. Researchers should contact the BLS at to determine the appropriate time frame for their project. Note that final revisions and journal submissions must be completed prior to an agreement’s end date.)  

  5. Resumes that include descriptions of the professional background and relevant research record of each individual who will access the data  

  6. Answers to the Researcher Supplemental Questions form (A zip file utility is necessary to extract this file. See http:/

Application Deadlines

The BLS has four application deadlines each year:  

  • January 15th 
  • April 15th 
  • July 15th 
  • October 15th  

Applications may be accepted in advance but will not be reviewed or processed until after the next application deadline. Generally, it takes approximately three months after the application deadline to receive approval for research proposals (5). Once a proposal is approved, it can take an additional three months to process and fully execute the legal agreement authorizing data access between the BLS and the recipient organization. Researchers should factor these estimates into their timetable for beginning research. 

All applications should be submitted electronically (in Word or PDF files). Please do not email "zip" files, as these will be automatically rejected by the BLS email screening mechanism. Applications should be sent to Carol Rowan at

Facilities Available Onsite

Accepted researchers will be assigned a member of the BLS staff who will be available to answer questions about the data files and assist with computer set up. No other research assistance is provided.  

To protect the confidentiality of the data, researchers are not permitted to store confidential data files on their own computer equipment.  The BLS will provide an IBM-compatible PC subject to the following four conditions: 

  1. The PC will be either stand-alone or connected to an internal server where the confidential data files are stored.  

  2. Each PC will be equipped with PC SAS. The server will be equipped both with SAS and Stata statistical software. On a case-by-case basis, a researcher may be permitted to load his or her own statistical software onto the PC or server provided that licensing agreements are observed.  

  3. BLS PCs will not provide access to e-mail or the Internet.  

  4. BLS staff will review all printouts, disks, reports, and other project outputs to ensure that data confidentiality is protected. 

Although researchers are allowed to bring microdata into the BLS national office for merging to confidential BLS microdata, any resulting merged microdata sets (with or without identifiers) are considered confidential and must remain onsite at the BLS national office.  

Visiting researchers may bring their own laptops to conduct outside work and to connect to the internet. BLS data may not be transferred to or stored on personal laptops at any time.  Please review the following policy statement: Visiting Researcher Policy on Laptops and Internet

1 BLS may only accept as many research projects as its limited resources (space, computer facilities, staff time, etc.) can accommodate. The summer months, mid-May through the end of August, and mid-December through mid-January are peak times for onsite research. 

At the present time the BLS is delaying additional access to the confidential data files of the Quarterly Census of Employment and Wages (QCEW) program as well all programs in the Office of Prices and Living Conditions (OPLC) due to the large number of research projects currently being undertaken with these microdata. When ongoing projects are nearing completion, BLS will again allow researchers to access QCEW and OPLC program data. Researchers are free to submit applications. When access to QCEW and OPLC program data resumes, researchers will be admitted in the order that their projects have been approved.

2 Access to confidential NLS Original Cohorts geographic data for statistical research involves a different application process than what is outlined on this webpage. For further information on how to obtain access to the NLS Original Cohorts geographic data, please contact the NLS program by email.

3 Access to the confidential microdata of the Quarterly Census of Employment and Wages program is considered only for research projects that do not involve tabular output. Proposals from Federal agencies for access to the QCEW data for research projects that involve tabular output will be considered.  

4 Foreign institutions are limited to non-profits and institutions of higher education. Researchers applying from foreign institutions should contact the BLS at to determine their eligibility prior to submitting an application as other complications may be a factor. Applications received from foreign institutions may take significantly longer to process. Researchers from international organizations (for example: the International Monetary Fund, the World Bank, and the United Nations) should contact to determine eligibility for this program.

5 Applications for access to Consumer Expenditure Surveys (CEX) data take longer because they must be approved by both the BLS and the U.S. Census Bureau.
