The pooled suicide rates of 23 cities & counties in Taiwan from 1983-1993 were examined using a cross-sectionally heteroscedastic & time-wise autoregressive technique. It was found that a combination of economic & social variables significantly accounted for the tremendous variations in suicide rates across Taiwan’s cities & counties & over time. Economic variables appeared to have greater impact on regional suicide rates than sociological correlates. In particular, the level of income per capita in a region stood out as the most important predictor of suicide rates.
