This article investigates the role of single parenthood ratios in predicting violent-crime rates (murders, rapes, assaults) of 39 countries and pitted the predictions of parental investment theory (calling for delayed effects) against those of mating aggression (calling for immediate effects). Regression analyses that controlled for masculinity of the population (sex ratio of 15- to 64-year-olds) and national wealth (log gross national product, GNP, per capita) found that current single parenthood ratios were strongly and consistently predictive of violent crimes, whereas single parenthood ratios 18 years ago were not. The results indicate that violent crime is best interpreted as a side effect of mating competition rather than as a function of reduced parental investment.
