Background: Suicide remains a leading cause of death in the United States, with more than 49,000 fatalities in 2023. Rural counties consistently face higher suicide mortality rates than urban areas, reflecting deep-seated mental health inequities. Methods: This study analyzes 39 U.S. states with suicide mortality rates exceeding the national average, as defined by the Centers for Disease Control and Prevention (CDC) (>14.1 per 100,000), to examine rural-urban disparities and their intersectional demographic factors. Age-adjusted mortality data (2019-2023) from HDPulse were analyzed using IBM SPSS Statistics, version 31.0. Counties were classified by USDA Rural-Urban Continuum Codes and stratified by region, sex, age, and race. Subgroup differences were tested using a two-way ANOVA (p < 0.01). Results: Rural suicide rates were significantly higher than urban rates (28.69 vs. 20.20 per 100,000; p < 0.001). The West reported the highest mortality and widest rural-urban gap (38.23 vs. 24.83), while the Northeast had the lowest. Men had higher rates than women, particularly in rural settings (37.12 vs. 11.77). The largest rural-urban gap occurred among young adults (20-39 years). American Indian/Alaska Native populations experienced the highest rates (rural: 58.73; urban: 35.15). The literature review highlighted limited healthcare access, social stigma, substance use, and economic hardship as variables commonly associated with rural-urban differences in suicide mortality. Conclusions: Suicide mortality is markedly elevated in rural America across all subgroups, with the greatest risks among young adults, men, and American Indian/Alaska Native populations. Tailored prevention strategies and expanded mental health infrastructure are critical for high-burden states.
