In 2020, over 45,200 deaths in the U.S. were caused by firearm incidents.  The 2020 firearm death rate of 13.7 deaths per 100,000 population was one-third higher than the 1999 firearm death rate of 10.3 deaths per 100,000 population.  Firearm death rates at the state level varied widely with some states experiencing far worse problems with gun-related deaths than others. The ten states with the lowest firearm death rates in 2020 had a collective death rate from gun incidents that was 48% lower than the national average.  A review of state-level data from the CDC's National Center for Health Statistics revealed the following to be the ten states with the lowest firearm death rates in 2020:
