This paper presents a new dataset of enrolment rates and grade distribution ratios (GDR) in Brazil between 1933 and 2010, in addition to enrolment rates and GDR of Brazilian states from 1955 to 2010. To our knowledge, there are no previous estimates of enrolment rates by states for such a long period in Brazil. Enrolment rates and GDR in northern and north-eastern states were meagre and comparable to the lowest Latin American performers, and even the most advanced Brazilian states lagged behind the early leaders of the region, such as Argentina and Uruguay, until the turn of the century. Given a certain enrolment rate, Brazilian states were expected to present lower GDR compared to Latin American countries on average.
