The suicide rate in the Republic of Korea remains among the highest in the world, which needs to be examined in various aspects. This study investigated factors associated with the suicide rates in Korea. The suicide rates of 251 districts in Korea in 2015 and their relationships with the prevalence of heavy drinking, health care provision, and religion as well as demographic characteristics were examined with a Pearson correlations and a multiple linear regression analysis. The suicide rate in Korea was 26.5 per 100,000 persons in 2015. The regression analysis showed that the income level of the region, as represented by the average national health insurance premium, had a negative association with the suicide rate and that the prevalence of heavy drinking and the percentage of the population aged 65 and above had positive associations with the suicide rate. While the unemployment rate and the proportion of Catholics showed negative relationships with the suicide rate in the correlation matrix, the association was statistically insignificant in the regression analysis. Special attention should be given to excessive drinking and socio-economically disadvantaged conditions in taking measures to prevent suicide.
