Having compiled, cleaned, and analyze data for over 52,000 homicides in 50 major cities in the U.S. going back to 2007, The Washington Post recently released an expansive report identifying patterns of justice and impunity, creating detailed maps of where murders go solved and unsolved. Within many cities they found areas with high murder rates but few arrests. Cities like Baltimore and Chicago were found to have large areas where murders are frequent but the likelihood of justice is slim. Citywide in Chicago, for example, there were 5,534 homicides between 2007 and 2017 with only 26% resulting in an arrest.
In other cities, like Atlanta, a different scenario was evident. Of the 973 homicides in Atlanta between 2007 and 2016, 62% resulted in an arrest. Additionally, as the homicide rate decreased over that period, the arrest rate increased.
Thanks to The Washington Post making their data public, continued analysis and transparency is possible. Below is an interactive dashboard we created using data extracted for the City of Atlanta. On the dashboard, you can filter the map by whether a homicide investigation resulted in an arrest or not as well as by the report date and the demographic characteristics of the victim.
