Public Use Data

Use Agreement for the Public Use Data Files from the Los Angeles Family and Neighborhood Survey

Thank you for your interest in the Los Angeles Family and Neighborhood Survey (L.A.FANS). You will need to complete a registration form in order to access the L.A.FANS Public Use data files from our server.

Please note that the L.A.FANS Public Use Data and documentation are provided as a public service to the research community. However, despite our best efforts, the public use files and data documentation provided on this website may contain errors. As with other data sets, researchers should proceed with caution and conduct their own data quality evaluations whenever possible.

We ask you to register for two reasons. First, summary information on L.A.FANS users helps us to demonstrate to agencies funding L.A.FANS that the data are useful to a broad range of researchers. This information helps us in our efforts to seek funding for future waves of L.A.FANS. Second, when possible, we will make an effort to notify registered data users of problems encountered or new data available.

To obtain access to the L.A.FANS Public Use Data, the User agrees to the following conditions:

  • You will make no attempt whatsoever to determine the identity of participants in the L.A.FANS study or of the specific neighborhoods, census tract, blocks, block groups, or streets in which study participants live.
  • You will use the data in the L.A.FANS data sets only for scientific research and aggregate statistical reporting.
  • You will not transfer the L.A.FANS Public Use Data or derived files to anyone else other than staff members and students working directly under your supervision. There is an exception to this condition for data libraries and archives. You will ask your co-investigators to register separately for data use.
  • You agree to destroy any downloaded Public Use Data files and any derived data files if requested to do so by RAND.
  • You agree to the citations for any papers, articles, books, working papers, presentations at professional meetings or conferences, or other publications based on the L.A.FANS data. We also ask that you send us copies of these publications. Electronic copies are preferred, though hard copies are accepted ( for our mailing address).
