Distribution dynamics of property crime rates in the United States

Using crime data for the 48 continental and conterminous US states and the distribution dynamics approach, this paper detects two distinct phases in the evolution of the property crime distribution: a period of strong convergence (1971-1980) is followed by a tendency towards divergence and bimodality (1981-2010). Moreover, the analysis reveals that differences in income per capita and police can explain the emergence of a bimodal shape in the distribution of property crime: in fact, after conditioning on these variables, the bimodality completely disappears. This empirical evidence is consistent with the predictions of a two-region model, that stresses the importance of income inequality in determining the dynamics of the property crime distribution.
