The purpose of this study is to measure intragenerational income mobility in Brazil and its several population subgroups within the period 1995-2005. To this end, the mobility axiomatic approach and dynamic instruments proposed by Aebi et al. (1999) are considered. Calculations of mobility indexes and the Markov transaction matrix indicate that Brazil presents low intragenerational income mobility, suggesting that its social structure is relatively rigid. Also, important heterogeneities within each subgroup were observed, thus corroborating the intergenerational results indicated by Ferreira and Veloso (2006).
