Firearm sales have hit historic highs in the U.S. in recent years, and the ongoing proliferation of firearms may be fueling a rise in gun crime.
When firearms are recovered at a crime scene or taken from a suspect, they are often reported to the Bureau of Alcohol, Tobacco, Firearms, and Explosives for tracing. In these cases, the ATF assists in criminal investigations by using serial numbers and other markings to determine when and where a firearm was originally purchased — and over the last 12 years, firearm-related offenses have been taking up a growing share of federal resources.
Between 2010 and 2022, the number of guns traced by the ATF surged by 174%, from 145,600 to 399,400, climbing by anywhere from 3% to 18% in a single year. Most homicides in the U.S. are committed with a firearm, and over the same period, the national homicide rate climbed by over 50%.
While not all guns traced by the ATF were used in a crime — and not all firearms used for illicit purposes are traced — federal tracing data offers valuable insight into trends and geographic patterns related to gun violence in the United States.
Mirroring the national trend, gun tracings are up sharply in Illinois. The ATF traced 7,273 seized firearms in the state in 2022, compared to 15,353 in 2010. Adjusting for population, gun crime now appears far more common in Illinois than it is across the U.S. as a whole. In 12 of the last 13 years, the number of firearm tracings for every 100,000 people in the state was above the comparable national rate.
As of 2022, the most recent year of available data, the ATF traced 122 seized firearms for every 100,000 people in the state, the 21st highest gun-tracing rate among states.
