This paper claims to show part of the relationship between the suicide rate and the economic behavior, expressed in the percentage variation of the GNP per capita. For that purpose, official figures on suicide and gross domestic product for period 1979-2007, are taken. First, a descriptive analysis on suicide data is done, finding that men commits suicide much more than women do (77%-23%), and the higher age rank, this proportion goes up even more. Also, it was found that people between 15 and 29 years old, represent half of total committed suicides (49,8%). Then, a correlation analysis between percentage variation of GDP per capita and rate of suicides per 100.000 habitants, was done, finding a high negative correlation (r=-0,91), and a high statistical significance was tested (p=0,000). Later, it is established a simple linear regression model between studied variables, that allows formulating a predictive equation of the suicide rates, based on the historical correlation between this variable and variation of GDP.
