Determinants of suicide rates: A spatial dynamic panel approach for microregions in Brazil

Abstract

This study investigates the impact of economic factors on suicide rates per 100,000 inhabitants in Brazilian microregions using a dynamic spatial panel approach. Data from the Mortality Information System (SIM) from 2006 to 2017 were used. The results identify clusters of high suicide rates in the South region and lower rates in the North and Northeast regions. An inverse relationship was observed between a positive economic situation and suicide rates, indicating that increases in Gross Domestic Product (GDP), employment, and greater investments in education, culture, social security, health, and sanitation have a negative impact on suicide rates. In addition, a favorable economic situation in neighboring microregions also contributes to the reduction of suicide rates. These results emphasize the need for effective public policies to reduce suicide rates, especially in the South region of Brazil, with special attention during periods of economic instability.
