Crimes and socio-economic environments

The purpose of this note is to study the relationship between crimes and the socio-economic environment in the metropolitan areas of the United States. In this study we define total crime rate per 100,000 population as a linear function of (i) per capita personal income, (ii) the unemployment rate (iii) the migration rate, (iv) racial imbalance, (v) climate, and (vi) males as a percentage of total population. Our statistical results confirm the hypothesis that social and economic conditions cause crime.
