High levels of school mobility are a problem in many urban districts. Many of these same districts are also dealing with high rates of violent crime. In this study, we use 6 years (2010-2011 to 2015-2016) of administrative data from Baltimore City public elementary school students and crime data from the Baltimore Police Department to examine whether changes in violent crime at schools are associated with the likelihood of school exit. Using logistic regression with school fixed effects to adjust for constant differences between schools, we find that students are more likely to leave following years with higher levels of violent crime at their school. These associations are strongest for students ineligible for free or reduced-price meals and from safer neighborhoods.
