This paper takes advantage of an unusually detailed family and youth survey conducted by the Institute for the Study of Work and Society (IETS) in Rio de Janeiro in the low-income community of Caju close to downtown Rio. It describes the weak educational background of Caju youth and some of the reasons for that weakness. The results emphasize the precarious nature of low-income youth’s educational achievements and their attachment to the job market. They also demonstrate the wide variance in youth characteristics even in a single low-income neighborhood.
