RT Article T1 A Note on the Use of County-Level UCR Data JF Journal of quantitative criminology VO 18 IS 3 SP 297 OP 318 A1 Maltz, Michael D. A2 Targonski, Joseph LA English YR 2002 UL https://krimdok.uni-tuebingen.de/Record/1764280628 AB County-level crime data have major gaps, and the imputation schemes for filling in the gaps are inadequate and inconsistent. Such data were used in a recent study of guns and crime without considering the errors resulting from imputation. This note describes the errors and how they may have affected this study. Until improved methods of imputing county-level crime data are developed, tested, and implemented, they should not be used, especially in policy studies.
