Suicide in the USA: A Decadal Study From the 1930s to the 2020s

Abstract

This study provides a decadal analysis of national suicide data over 90 years, offering a comprehensive view of long-term trends and current levels in the United States. We analyzed mean decadal suicide numbers, rates, and confidence intervals from the 1930s to the early 2020s across demographic categories including sex, race, and age. Our findings reveal that suicide rates in the 2020s are the highest since the 1930s. The data indicate significant variations across groups; the 2020s show the highest suicide rates for both Whites and Nonwhites, and individuals under 44 years of age. Conversely, men’s suicide rates were slightly lower than those in the 1930s, whereas rates for women and older adults peaked during the 1930s. The results underscore the need for ongoing surveillance of suicide trends and proactive suicide prevention measures by governmental and other relevant organizations.
