This report was produced by RTI International for BJS under award number 2020-85-CX-K017. The purpose of the research described in this report is to (1) examine the presence and impact of outlier cases in the National Crime Victimization Survey (NCVS ) data, (2) develop a strategy for identifying these cases and mitigating their effects, and (3) evaluate the impact of this strategy on annual estimates, the precision of estimates, and trends in victimization over time. This work was conducted as part of BJS’s active research program on weighting, designed to improve the quality and accuracy of NCVS estimates.
