Long‑Term Trend Shows Arrest Percentage Falling from 31 % in 2005 to 12 % in 2021
Data compiled by the Chicago Sun‑Times illustrates a steady decline in the share of crimes that result in arrest over a 16‑year span. In 2005, police recorded arrests for 31 percent of the 254,900 reported incidents; by 2010 the rate had slipped to 25 percent, and it continued to erode to 18 percent in 2015.
