Nationwide firearm-related mortality rates increased in 2015-17 after remaining relatively stable in 1999-2014. Recent increases are reflected across most states and demographics to varying degrees, which suggests a worsening epidemic of firearm mortality that is geographically and demographically broad. In both time periods the fractions of firearm deaths due to suicide and homicide remained consistent.
