Most studies looking into the relationship have concentrated on homicides since homicides are almost identically defined across all nations and jurisdictions.

Research has been conducted comparing developed countries with undeveloped countries, as well as studying areas within countries. Daly et al. 2001 found that among U.S States and Canadian Provinces there is a tenfold difference in homicide rates related to inequality.

(2002) found a similar relationship worldwide. Among comments in academic literature on the relationship between homicides and inequality are:
What has crime rate been shown not to be correlated with in a society?
