A worldwide survey of victims shows racial differences in crime: In Race, Evolution, and Behavior, Phillip Rushton used international law enforcement data (Interpol) to show that blacks globally have higher rates of criminal violence than Asians. Critics have pointed out that the data were collected by disparate national systems, and that Interpol itself says that the data are not comparable. A better approach is to use data from the International Crime Victimization Survey. This survey publishes estimates of crime from nationally representative samples of respondents who are given a list of crimes and are asked if they have been a victim in the past 12 months. Here are the prevalence rates (the percent of the population victimized in the past year) for "assault with force" for the latest year available:

Zimbabwe 6.7%
South Africa 4.6
Botswana 3.7
Uganda 2.4
Indonesia 1.1
China 0.9
Philippines 0.4

This kind of survey data is much more persuasive evidence of worldwide racial differences than officially recorded violent crimes.
