National Inmate Survey (NIS) - Prisons: Full Survey Respondents, [United States], 2008-2009

Each interviewed inmate was assigned an initial weight corresponding to the inverse of the probability of selection within each sampled facility. A series of adjustment factors was applied to the initial weight to minimize potential bias due to nonresponse and to provide national estimates. The data file contains the final weight variable WT_FINAL and 30 replicate weights (REPWT##). Please refer to the codebook for details about the creation and adjustment of the weights provided by the Principal Investigator.
