| Summary: | <p> This study includes restricted data version 2.5, for Wave 1 of the L.A.FANS data. To compare L.A.FANS restricted data, version 2.5 with other restricted data versions, see the table on the series page for the L.A.FANS data <a href="https://www.icpsr.umich.edu/icpsrweb/DSDR/series/846">here</a>. Data in this study are designed for use with the public use data files for L.A.FANS, Wave 1 (study 1). This file adds only a few variables to the L.A.FANS, Wave 1 public use files. Specifically, it adds the census tract and block number for the tract each respondent lives in. It also includes certain variables, thought to be sensitive, which are not available in the public use data. These variables are identified in the <a href="https://www.rand.org/pubs/drafts/DRU2400z2-1.html">L.A.FANS Wave 1 Users Guide and Codebook</a>. Finally, some distance variables and individual characteristics which are treated in the public use data to make it harder to identify individuals are provided in an untreated form in the Version 2.5 restricted data file. Please note that L.A. FANS restricted data may only be accessed within the ICPSR Virtual Data Enclave (VDE) and must be merged with the L.A. FANS public data prior to beginning any analysis. </p> <p> A Users' Guide which explains the design and how to use the samples are available for Wave 1 at the <a href="https://www.rand.org/pubs/drafts/DRU2400z2-1.html">RAND website</a>. </p> <p> Additional information on the project, survey design, sample, and variables are available from: </p> <ul> <li>Sastry, Narayan, Bonnie Ghosh-Dastidar, John Adams, and Anne R.
