The Crime and Justice Policy Lab (CJP) at Penn is conducting a study investigating litter’s effects on gun violence rates in Philadelphia. My research project will expand upon this idea investigating the relationship between litter and gun violence in Philadelphia from 2017-2019. Using a correlational analysis, linear regression, and Poisson regression, I determine how litter affects gun violence rates, also factoring in median income, median home value, poverty, unemployment, and lot vacancy throughout Philadelphia.
