description: 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 here. 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 L.A.FANS Wave 1 Users Guide and Codebook. 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. A Users' Guide which explains the design and how to use the samples are available for Wave 1 at the RAND website.

description: L.A.FANS is based on a stratified random sample of 65 neighborhoods (census tracts) in Los Angeles County, California. Poor neighborhoods were oversampled. In Wave I, an average of 41 households were randomly selected and interviewed within each neighborhood, including an oversample of households with children under 18. Within each household, both adults and children were sampled and interviewed. Each sampled person was interviewed in the first wave and tracked and reinterviewed in the second wave, whether they remained in the neighborhood or moved elsewhere in Los Angeles County. Information on Wave 1 respondents who could not be reinterviewed in Wave 2 was collected from other household members. In the second wave, a fresh sample of households that had moved into the neighborhood in the period between waves was also selected and interviewed. The first wave (L.A.FANS-1), which was fielded between April 2000 and January 2002, interviewed adults and children living in 3,085 households in a stratified probability sample of 65 neighborhoods throughout Los Angeles County. The samples of neighborhoods and individuals were representative of neighborhoods and residents of Los Angeles County. Poorer neighborhoods and households with children were oversampled. In Wave 2 of L.A.FANS, Wave 1 respondents living in Los Angeles County were reinterviewed and updated information was collected on Wave 1 respondents who had moved away from Los Angeles County. A sample of individuals who moved into each sampled neighborhood between Waves 1 and 2 was also interviewed, for a total of 2,319 adults and 1,382 children (ages less than 18 years). Additional information on the project is available at the L.A.FANS website.
