The Effect of Weather on Crime in a Torrid Urban Zone

This study investigates the relationship between weather and crime in Barranquilla, Colombia, a city in the Torrid Zone, which in contrast to more commonly studied temperate zones is hot and humid year-round. Our analysis is based on daily variations in four weather variables (temperature, relative humidity, precipitation, and wind speed) and two indicators of criminal activity, namely, homicides and interpersonal violence. To help identify statistical links, we add controls for temporal variables. Using count data models in the estimations, we do not find any statistically significant relationship between weather patterns and homicides. However, we find that weather can be an important predictor of interpersonal violence in this area. These findings draw attention to the importance of considering weather factors when designing a long-run urban security policy in one of the world’s most vulnerable regions to climate change.
