This study aims to investigate the pattern of transformation of the Brazilian income distribution its geographic regions in the period 1987 - 2003. It also intends to identify the underlying factors of such transformation, specifically, the income and educational mobilities. To achieve that, static and dynamic tools have been used. Among those tools, the polarization measures proposed by Duclos et alii (2004) and the matrix transition of probability can be highlighted. The results show a great change in the Brazilian income distribution. In general, it was observed a polarization of the wages featured by an increase in both the bottom and the top salary levels. These changes were followed by a strong educational mobility related to a decrease in the parental effect. However, differences among the regions connected to that process could also be found.
