Views: New Fed Study Examines Crime Rates at the City Level

Whether a community is perceived as a desirable place to live and visit is determined, in part, by its crime rates. Naturally, crime rates are important to a community’s economic success and have been the topic of numerous academic studies. Most of these have used data at the county, state or national level to explore long-term relationships between economic conditions and crime and between deterrence and crime.

A new study from the Federal Reserve Bank of St. Louis, Local Crime and Local Business Cycles, narrows the data down to the city level and looks at whether economic conditions and deterrence affect the short-term growth rates of seven major crimes: murder, rape, assault, robbery, burglary, larceny and motor vehicle theft. Authors Tom Garrett, St. Louis Fed economist, and Lesli S. Ott, senior research associate, zero in on monthly data for 23 large cities in the United States, including St. Louis, Memphis, Little Rock and Louisville.

Overall, Garrett and Ott found little evidence that changes in a city’s economic conditions or its number of arrests significantly affected short-term crime rates. This suggests that short-run changes in economic conditions do not induce individuals to commit crimes. That being said, the authors did find that short-term economic changes in some of the cities influenced crimes against property. “This likely reflects the fact that nonviolent property crimes are more likely to result in financial gain than violent crimes,” the study says.

The authors also found strong evidence that law enforcement reallocates its resources in response to increases in crime, especially those that are more visible to businesses and tourists, such as robbery, vehicle theft and assault.

Finally, the study revealed that relationships between economic conditions and crime and between deterrence and crime are not likely to be the same across cities or regions. This suggests that, to implement effective public policy at the local level, it is important to conduct local analyses, using more disaggregated data.
