Changes in Suicide Rates in the United States From 2022 to 2023
Introduction:
This report provides final 2023 mortality rates for suicide and shows changes in rates by age group, sex, and state of residency between 2022 and 2023.
Methods:
This analysis used National Vital Statistics System underlying cause-of-death mortality data for 2003 through 2023 on CDC WONDER. Suicide deaths were identified using International Classification of Diseases, 10th Revision underlying cause-of-death codes U03, X60-X84, and Y87.0. Age-adjusted and age-specific death rates (deaths per 100,000 population) were calculated, with differences tested using z tests for pairwise comparisons and Joinpoint software to evaluate trends.
Key Findings:
The overall age-adjusted suicide rate increased from 2003 (10.8 deaths per 100,000 population) to 2018 (14.2) but did not significantly change between 2018 and 2023 (14.1). From 2022 to 2023, the suicide rate increased for females age 75 and older and decreased for males age 75 and older. The age-adjusted suicide rate significantly changed from 2022 to 2023 for five states: increasing for Arkansas and decreasing for North Dakota, Iowa, Connecticut, and Arizona.
