Using mortality data from the National Vital Statistics System, this report examines suicide rates and methods among young adults aged 18–24, by sex and race and Hispanic origin. Results show that young adult males were more likely than young adult females to commit suicide across racial and ethnic groups. The suicide rate was highest among the American Indian or Alaska Native (AI/AN) population, and likely to be underreported. Non-Hispanic black and non-Hispanic white young adults were most likely to use firearms, followed by suffocation. Hispanic, Asian or Pacific Islander (API), and AI/AN young adults were most likely to use suffocation, followed by firearms.
