In 2020, more than 45,200 deaths in the U.S. were the result of firearm incidents.  At 13.7 deaths per 100,000 population, the 2020 firearm death rate was 33% higher than it was twenty-one years earlier in 1999 (10.3 deaths per 100,000 population).  While the 2020 national firearm death rate stood at 13.7 fatalities per 100,000 population, at the state level there was much disparity in death rates with some states experiencing far worse problems with firearms-caused deaths than others.  The ten states with the highest firearm death rates in 2020 had a collective death rate from firearm incidents that was over 75% higher than the national average.  Further examination of data from the CDC's National Center for Health Statistics revealed the following details for the ten states with the highest firearm death rates in 2020:
