The clustered variant of the Least Absolute Shrinkage and Selection Operation (LASSO) framework is employed to select the determinants of suicide in the USA and a Least Squares Dummy Variable (LSDV) approach is then employed to estimate the ‘natural rate of suicide’ at the state level. Our model suggests that over the 2005-2017 period, natural rates for US states ranged from 5.5 (DC) per 100,000 population per year to 18.8 (Montana). Our results support the natural rate hypothesis with a more robust specification. We also consider the use of the natural rate measures as a means of evaluating progress in increasingly influential zero suicide initiatives.
