Table 3 Comparison of Gini coefficients for studies using police data and those using survey data

From: Compared to what? Estimating the relative concentration of crime at places using systematic and other reviews

  1. Data points are ordered pairs of numbers, where the first number is a percent of the places or people studied and the second number is the percent of crime involved with these places or people. For example, 15, 70 would indicate that 15% of the places examined had 70% of the crime found in the study, or that 15% of the people surveyed had 70% of the victimizations detected in the study. This is described in Lee et al. (2017) and in O et al. (2017)
