Homicide clearance rates have decreased to their lowest level from 71 per cent in 1980 to around 50 per cent in 2020, according to analyses of FBI data by the Marshall Project and Murder Accountability Project.
America is now at risk of becoming the first developed nation where the majority of murders go uncleared, according to Thomas Hargrove, founder of the Murder Accountability Project, which tracks unsolved homicides in the US.
Although US police have solved more murders than in any year since 1997, because of the increasing number of homicides, the clearance rate has dramatically declined to a little below 50 per cent.
Clearance rates are the metric used to determine how many homicides police solved according to FBI reports.
