Democracy, Egalitarianism and the Homicide Rate: An Empirical Test of a Variety of Democracies, 1990–2019

Abstract Democracy and the level of economic development correlate tightly. While some argue that egalitarian conditions inherent in democracies reduce homicide, others suggest that it is economic development that matters. This study evaluates competing theory and tests the democracy—homicide link using homicide data defined as death due to interpersonal violence and novel data on a variety of democracies. The results show that democracies associate positively with homicide, and egalitarian democracy shows the strongest effect. The level of economic development is negative on homicide and substantively large. The basic results are robust to alternative data, estimating method, and to omitted variables bias.
