This study tests the broken windows theory of crime by examining the relationship between 311 calls for service and crime at the street segment and intersection level in Washington, D.C. Controlling for a set of micro level covariates, as well as unobserved neighborhood level effects using negative binomial regression models, it is found that detritus and infrastructure related calls for service have a positive, but small effect on crime. The results suggest that 311 calls for service are a valid indicator of physical disorder where available, and the findings partially confirm the broken windows theory. Given the small effects though, reducing physical disorder is unlikely to result in appreciable declines in crime.
