Suicide deaths by occupation skill level and educational attainment in the United States

To estimate the association between suicide deaths and both occupational skill level and educational attainment in the United States.

Suicide deaths, employment, education, and demographic data from the 2021 National Center for Health Statistics Multiple Cause of Death Files, for ages 18-64 with a lifetime history of employment, were combined with comparable participants from the 2020-2022 Current Population Survey. Outcomes of interest were associations between suicide death and occupational skill level, assessed as a 5-level variable, and educational attainment. Logistic regression models were used to estimate these associations before and after adjusting for educational attainment, age, and sex, in each racial/ethnic subpopulation.

We found a significant gradient in suicide death across occupational skill levels, with lower-skill occupations associated with higher suicide rates than higher-skill occupations. This gradient was more pronounced among non-Hispanic White (NHW) people and non-Hispanic Black (NHB) people than Hispanic people. However, upon controlling for educational attainment, this association was attenuated, indicating that the initial link was likely confounded by education.

The results suggest that educational attainment is a more robust predictor of suicide risk than occupational skill level. Targeted interventions addressing educational and ethnic disparities within higher-risk occupational groups can mitigate suicide risk.
