What's New

Consistent Occupation and Industry Codes for L.A.FANS-2 and L.A.FANS-1

Occupation and industry codes based on those used in the 2000 Census have been assigned to jobs described in the Adult and EHC modules of Waves 1 and 2 of the L.A.FANS. These separate data files of jobs with assigned occupation and industry codes, which include linking identifiers, provide consistent coding between the two Waves. Please see the Public Use Data and Restricted Data Version 2 descriptions for more information.

Variable Formats for L.A.FANS Wave 1 Data Are Now Available

Versions of the Wave 1 SAS and Stata data files with variable formats incorporated are now available. For those who already have Wave 1 data and want to apply the formats themselves, we have also made available the relevant SAS and Stata code to do so, available here.

Final Public Use Data from Wave 2 of L.A.FANS Are Now Available

The final L.A.FANS-2 public use data are available here.

This release includes anthropometry and blood pressure measurements, but it does not include blood- or saliva-based biomeasures or spirometry. The release of all lab-based bio-measures and spirometry measurements is delayed until later in 2016.

L.A.FANS-2 Restricted Data Are Now Available

To apply for the L.A.FANS-2 restricted data, please follow the procedures described below. Contact us with questions regarding the application procedures by e-mail at lafansapplications@rand.org.

New L.A.FANS Restricted Data Application

  • Follow the instructions for current restricted data applications (described here).
  • Justify the use of restricted data from both Wave 1 and Wave 2 based on the project aims.
  • Submit all application materials electronically to lafansapplications@rand.org
  • The application fee is $650 for Versions 2, 2.5, or 3 of the restricted data and is $150 for Version 1. Processing fees are to be paid by check payable to RAND with the P.I. name noted on check and mailed to:
    L.A.FANS Database
    RAND Corporation
    1776 Main Street, P.O. Box 2138
    Santa Monica, CA 90407-2138
  • Note that the L.A.FANS Data Use Agreement now includes:
    • The possibility of unannounced site visits to verify that data users are complying with their data safeguarding plan and the Data Use Agreement.
    • A requirement for users to submit electronic copies of all publications and documents (e.g., journal articles, manuscripts, reports, book chapters, dissertations, and working papers) and all presentations (e.g., slides or posters) based on the L.A.FANS restricted data as part of their annual review.

Adding Wave 2 Restricted Data to an Existing Contract

Users who have an active Wave 1 Restricted Data Use Agreement can apply to receive the Wave 2 Restricted Data. An amended application will need to be submitted that includes:

  1. A brief justification for the use of the Wave 2 data that is consistent with the approved research plan for the Wave 1 restricted data.
  2. An updated Data Protection Plan (or written assurance that the approved plan remains unchanged).
  3. An updated list of all supplemental data users, with a signed Supplemental User Agreement for any new users.
  4. A list and electronic copies of all publications and documents (e.g., journal articles, manuscripts, reports, book chapters, dissertations, and working papers) and all presentations (e.g., slides or posters) based on the L.A.FANS restricted data (since the beginning of the project or since the previous submission of these materials, if applicable).
  5. Documentation of current full IRB approval (expedited review is acceptable in only limited circumstances—contact the L.A.FANS project by e-mail at lafansapplications@rand.org for details).
  6. An update about the current status of federal funding for the project or center that supports research using Version 3 Restricted Data (federal funding is only a requirement for Version 3 of the L.A.FANS restricted data, not for Versions 1, 2, or 2.5).
  7. Payment of a $250 application fee.

An Addendum (PDF) to the existing Data Use Agreement will be required for all users with a current agreement who would like to obtain the Wave 2 Restricted Data. The addendum will include:

  1. The possibility of unannounced site visits to verify that data users are complying with their data safeguarding plan and the Data Use Agreement.
  2. A requirement for users to submit electronic copies of all publications and documents (e.g., journal articles, manuscripts, reports, book chapters, dissertations, and working papers) and all presentations (e.g., slides or posters) based on the L.A.FANS restricted data as part of their annual review.

The end-date of the user's contract will remain unchanged. However, users who are in their original contract period (i.e., those who have not received an extension or renewal) can apply for a one-time contract extension (for up to one year) or a one-time contract renewal (for up to three years) at the same time as requesting the Wave 2 data. To obtain an extension or renewal, the user must submit a written justification for the extension or renewal along with the other required items described above. Users requesting an extension should submit a completed and signed Extension Request Form (PDF).

If there is a change in the research plan, an entirely new restricted application is required.
