The 18-20 age group has a higher likelihood of risky and aggressive behaviors and an elevated risk for suicide.

Increasing the minimum age from 18 to 21 will help protect young people and the public at large.

This act would increase the age from 18 to 21 years for lawful sale of firearms or ammunition. Full-time law enforcement, state marshals and members of the U.S. military would be exempt from these prohibitions.

Research Shows that the Human Brain Continues to Develop Well Past the Age of 21

The parts of the brain responsible for impulse control, judgement, and long-range planning are among the last areas of the brain to fully mature, and in fact, may continue to develop until at least age 26.1

The developing brains of adolescents and young adults may put them at higher risk of making risky decisions. Hormonal changes can have significant effects on self-control, decision making, emotions, risk-taking behaviors, and aggressive impulses.2

The 18-20 age group has a higher likelihood of risky and aggressive behaviors.

A study of offenders incarcerated for crimes committed with firearms found that 17% of offenders would have been prohibited from buying a gun if their state had a law that raised the minimum age to possess a handgun to 21 years.3

In 2019, 28,568 young people ages 10 to 21 were arrested for weapons offenses, such as llegally carrying or possessing a firearm. This group made up 26% of all arrests for weapons offenses that year.5

Hormonal changes in adolescents and young adults can have significant effects on self-control, decision making, emotions, risk-taking behaviors, and aggressive impulses.6

The 18-20 age group is at an elevated risk for suicide.

Risk is much higher in the early stages of the onset of major psychiatric conditions, and these symptoms usually first develop in adolescence or early adulthood.7

Suicide attempts that result in death or hospital treatment peak at age 16, but are at the highest rates from age 14 through age 21.8

Gun access can significantly increase these risks. The association between firearm availability and suicide is strongest among adolescents and young adults.9

Minimum Age Laws are Effective

One study found that state laws raising the minimum legal age to purchase firearms to 21 years were associated with a nine percent decline in rates of firearm suicides among 18-to-20-year-olds.10

Controlling for other factors, unintentional firearm deaths and firearm suicides among youth (ages 0-19) also fell after the federal minimum age law was enacted.11

A Deadly Example of the Lack of Judgement and Risky Behaviors of the 18-20 Age Group:

  • Kyle Rittenhouse was 17 when he killed 2 and wounded another with his assault weapon in Kenosha, WI in 2020.

  • Dominick Black was 18 when he bought the gun for Rittenhouse.

Rittenhouse was 17 when he killed 2 and wounded another.

It’s About Public Safety

It is time to put public safety first and join with these states and increase the minimum age to buy guns.
