Gun violence data consistently suggest there are more firearm deaths in states with lax gun control laws.
In an analysis of recent gun death data from 2015-2019, the Bay Area News Group found "a strong correlation between strict state gun laws and lower overall firearm fatality rates," particularly for firearm suicides. The correlation was weaker for firearm homicides: since gun homicides cluster in cities, some rural states with relaxed gun control laws nonetheless had low gun homicide rates.
In a separate analysis of FBI data, the Washington Post found that in the eight states permitting authorities to exercise discretion over which applicants receive gun permits, gun homicides were lower in the period 2016-2020.
In a third analysis of CDC data, Joslyn Law Firm reported, "The vast majority of states with the most gun homicides are states that score a 3 or higher for gun-friendliness."
