This paper uses a sample of 150-200 households and 25 communities from the Mexican Migration Project to examine how village migration patterns affect infant survival outcomes in sending communities in Mexico. The authors’ main hypothesis is that migration is a cumulative process with varying health effects at different stages of its progression. Their results suggest higher rates of infant mortality in communities experiencing intense U.S. migration. However, their findings also suggest that the impact of migration on infant survival changes over time due to inflow of migrants’ remittances and the institutionalization of migration. Mortality risks are low when remittances are high and decrease as migration experience increases in a community. The authors conclude that migration is likely to yield eventual health benefits to all infants over time. The results do not deal with the selectivity of the migration process.
