Adolescents and youths are marrying or forming conjugal unions later, and they are older when they have their first child or leave the family home (ECLAC, 2000). This change, however, does not affect all adolescents and youths in equal measure. Rather, it has become a highly stratified process. This stratification is associated with structural conditioning factors (Filgueira, 1998, p. 66) associated with divisions caused by inequality and essentially resulting in postponement of the assumption of adult roles in the more educated and higher-income sectors, as opposed to early assumption of these roles in lower-income ones (Ullman, 2015).
