Sunmmary: 1. There are vast differences in homicide rates between groups This “effect” is found consistently in aggregated and (racially) disaggregated data Inter-racial differences are better explained by family structure than economic conditions. 2. These differences are even found in some pretty affluent/low-poverty communities 3. The (intra-racial) black homicide rate, in particular, is better explained by family structure than poverty rates and, especially, other economic measures. 4. There are large differences in family structure between whites and blacks, in particular. It’s probably not a coincidence that other groups fall closely along this regression line when aggregated at national or even state levels. 5. The inter-racial differences in family structure are not well explained by income or poverty measures, i.e., (domestic) blacks of the same income level have much lower levels of traditional family structure.
