Last time I wrote about violent crime in Chicago dropping by 44% since 2001. Then I examined two community areas in the 25th ward, the Lower West Side and the Near West Side. While they had drops in crime of 30% and 17% percent respectively, that changed after accounting for their dramatic changes in population. Lower West Side population is down by 25%. Near West Side population is up by 35%. That means their per capita crime has dropped 13% and 34% respectively. This left me with a few questions for the city at large: What are the population changes? How have crime rates changed? How have per capita crime rates changed?
