*p < .01

**p< = .05; Full sample represents 847,928 census block group month-years for crime and 341,962 census block group month-years for arrest.

Note: Total crime includes the sum of all 52 different crime categories consistently recorded. Total arrest includes the sum of all 65 arrest categories consistently recorded. Number drops in burglary arrest category because there are no burglaries in 3,495 census block groups. Arrest data are missing for 5 months of 2012. Robust standard errors are in parentheses.
