This study investigates the effects of gentrification on criminal behavior in urban neighborhoods to assess whether or not this phenomenon is destructive to commu-nities. To identify gentrified neighborhoods in the 2010s, the study employs a newly constructed, unique data set of geo-referenced crime records from 14 major Ameri-can cities paired with Census data. To examine the effect of gentrification on crime, I employ state-of-the-art event study models to evaluate the consequences of gen-trification, accounting for variations in the timing of this process between cities and neighbourhoods. The results shows that gentrified neighborhoods faced a statisti-cally significant increase in crimes estimated between 11 to 17 percent, with property crimes showing the most significant increases. Overall, the study indicates that gen-trification may have a criminalizing influence on areas, underlining the need for ad-ditional policy consideration of this issue by urban planners and scholars.
