Important findings from the analysis:
- In 2013, there were 21,175 suicide deaths by firearm and 11,208 homicide deaths by firearm.
- Across the lower 48 states, homicide rate by firearm has gone down slightly on average from 1999 to 2013; however, during that time, suicide rate by firearm has increased more so than homicide rate was reduced.
- Large Central Metro counties were the only places where homicide rate was greater than suicide rate for all years, and Large Central Metro counties also showed the largest reduction in homicide rate from 1999 to 2013. Large Central Metro counties were also the only areas that did not experience significant increases in suicide rates during this time period.
- Despite lower rates of homicide in rural/non-metro counties, increased rates of suicide resulted in total death rates by firearm to be equal to or larger than that of large central metro areas.
- Age groups 15-24 and 25-34 years old were the only age groups where homicide rates (9.9 and 8.5, respectively, per 100k) were greater than suicide rates for all years.
- Middle-aged adults (45-54 and 55-64 years old) showed the largest increases in suicide rates by firearm, while 75+ year olds have the highest reported rate of suicide (12.5 per 100k).
- The states with the highest homicide rates on average from 1999 to 2013 were Louisiana, Mississippi, and Maryland. The states with the highest suicide rates on average were Wyoming, Montana, and Nevada.
