This paper analyzes the relationship between property crime and socioeconomic factors by choosing section data of American states from 2011 to 2015. The research shows that: 1) The factors—unemployment rate, median household income and education level do not strong affect the change of property crime; the covered people of unemployment insurance policy and law enforcement are significant for variance to property crime. 2) Economic determinants should be included in the model of criminal activity, but the economic model does not explain the overall change in crime rates.
