Abstract: Mexico's 1993 reform extended compulsory schooling from six to nine years, creating a birth-cohort discontinuity in educational exposure. Using a regression discontinuity and instrumental variable design in the 2020 Mexican Census, this paper traces the reform's effects from educational attainment through fertility, child mortality, employment, and migration, into the schooling of the next generation. The reform raised attainment across all groups, but its effects were concentrated among Indigenous communities and rural populations, where baseline attainment was lowest: Indigenous literacy rose by 4.5 percentage points and lower-secondary completion by 3.8, from baselines of 78 and 29 per cent. These gains translated into lower fertility, reduced child mortality, higher employment, and a reallocation of workers out of low-productivity agriculture into higher-productivity sectors. Linking parents to children through census household identifiers, an additional year of parental schooling raised children's secondary enrolment by 3 to 4 percentage points and upper-secondary enrolment by 5 to 8. A single compulsory schooling reform thus generated a sustained, multi-domain shift in life trajectories extending across generations.
