Evidence demonstrates that background checks save lives. For example, in the fourteen states that already require background checks for all handgun sales:
- Gun trafficking is 48 percent lower than in states that fail to require background checks for all handgun sales.
- In 2010, the rate of women murdered by an intimate partner with a gun was 38 percent lower than in other states, while the rate murdered by other means was nearly identical.
- The firearm suicide rate was 49 percent lower than in other states, even though people committed suicide in other ways at almost precisely the same rate.
- In 2011, of states with sufficient data, those that required background checks for all handgun sales had 17 percent fewer firearm aggravated assaults, controlling for population.
