This research examined the influence of gold mining on regional development in four Brazilian states: Minas Gerais, Pará, Goiás, and Bahia. The study used the Pearson correlation method to analyze data on the Human Development Index (HDI) and Per capita income in these states from 2010 to 2020. The findings revealed a weak correlation between gold mining activity and most states' HDI or Per capita income. However, Bahia presented a slight positive correlation, with 61.39% for HDI and 60.76% for GDP Per capita. This suggests a possible link between mining and development indicators, specifically in Bahia. In contrast, another analysis focused on Jacobina, a gold-producing region. Here, the results showed a strong correlation between gold production and the presence of companies. This implies that mining activity can stimulate the local economy by creating jobs and generating income. This income increase, in turn, could potentially improve quality of life and reduce hospitalizations (based on a high negative correlation, r = -0.89). Additionally, the study identified a high level of indirect correlation between gold production and other socioeconomic factors in Jacobina, suggesting a broader influence of mining on the region's well-being.
