The fourth report (and first from phase II), Mapping Mobility of Individuals Arrested for Misdemeanors in New York City, 2006-2014 examined longitudinal trends in the mobility of individuals arrested for a misdemeanor in New York City. We analyzed geospatial patterns of the relationship between the precinct of residence (i.e. where an individual lives) and the precinct of arrest for a misdemeanor in New York City over the last eight years. This study examined variation in mobility at the borough and precinct level. We also examined whether demographics and charges varied by mobility (i.e., being arrested outside the precinct of residence for a misdemeanor). Lastly, we included five in-depth (one precinct for each borough) case studies to illustrate the concept of mobility at the precinct level.
