Previous research has shown that higher per capita income increases the chances of establishing democracy and undermines the further maintenance of authoritarian regimes. Many authors attribute different contextual factors, in addition to per capita income, to the impact of democratization while some em phasize education, others refer to civil war and income equality. This paper takes into account the conclusions of previous authors and includes a series of predictors in the model of logistic regression in order to determine whether economic development is the primary predictor of democracy and whether this effect differs with respect to the region and type of ideology. Equally, it seeks to establish the minimum limit of per capita income that encourages the democratization process of authoritarian regimes. A marginal representation of GDP effects shows that undemocratic regimes, once they reach $30,000 in per capita income, are very likely to begin a process of democratic transition. At higher levels of GDP, this effect is lost. With natural resource revenues, it was observed that they had no impact on the likelihood of democratization, suggesting a change in the narrative regarding democratization in countries rich in natural resources. On the other hand, the most significant predictors of democratization are dispersion of political power and lower urbanization rates.
