This article investigates suicide trends and geographical distribution in the US, developing a machine learning model to predict suicide rates at the county level using data from 2010-2019. Analysis revealed significant increases in suicides across many counties. An XGBoost model, utilizing 17 features, achieved an R² of 0.98. SHAP analysis identified key features like total population, % African American population, % White population, median age, and % female population. These features were used to create a Suicide Vulnerability Index (SVI) for US counties, aiding targeted suicide prevention efforts.
