Micro-Place Homicide Patterns in Chicago 1965 – 2017 – PDF/EPUB Version Downloadable

This brief examines 36,263 homicides in Chicago over a 53-year study period, 1965 through 2017, at micro place grid cells of 150 by 150 meters. This study shows not only long-term historical patterns of homicides in Chicago, but also places that historical context of homicide in reference to the dramatic increases in homicides in 2016-2017. It uses several different inequality metrics, as well as kernel density maps to demonstrate that homicides were more clustered in the 1960’s compared to later periods. Using zero inflated group-based trajectory models, it demonstrates the long-term temporal stability of homicides at micro places. This brief will be of interest to researchers in policing, homicide, and research methods in criminology.
