O efeito da estrutura familiar sobre a estratificação educacional no Brasil: evidências com base na probabilidade de progressão por série entre 1986 e 2008

The aim of this paper was to investigate differentials on inequalities of educational opportunities between nuclear families and single parents families. The motivation to work is to verify if the result of literature which predicts a negative effect of belonging to a single parent family on educational outcome is true for Brazil. We used logistic school transition models and test the hypotheses of Mare (1979, 1980, 1981), which are: decline throughout the series of the effects of social origins in a given period; decline of the social origins effect in a given grade between two periods when there is an educational expansion. Our results show that the behavior of inequality of educational opportunities is generally similar among intact and not intact families. However, we found that women single parents were more benefited from the educational policies with a substantial reduction in inequality of educational opportunities in the early school transitions. For the other variables found no significant differences between nuclear families and single parenthood.
