Based on the well-known and strong relationship between suicide and depression, the authors investigated the regional distribution of the suicide rates, rates of diagnosed depressions and rates of working physicians in Hungary. It was found a strong significant positive correlation between the of working doctors and rate of diagnosed depressions, and both the mentioned parameters showed a strong significant negative correlation with the suicide rates. The more is the number of doctors/100,000 inhabitants, the better is the recognition of depression and the lower is the suicide rate in the given region. The rate of working doctors was significantly higher in the countries located in the western part of Hungary, which may have a role in the lower suicide mortality of this area of the country.
