Co-residence choices represent an under-studied topic in economics, where household composition is often regarded as exogenous. The migration literature makes no exception in this respect, relying on the assumption that the migration of a household member is not systematically associated with further variations in co-residence choices. We rely on a large Mexican rotating panel survey to provide empirical evidence on the correlation between the occurrence of an international migration episode and additional changes in household composition. Migrant households have a 39 percent higher probability of receiving a new member over a one-year period around the migration of one of its members. Attrition is significantly higher among migrant households, and we provide suggestive evidence that this is due to the dissolution of the household of origin of the migrant, with the members left behind joining another household. The observed endogeneity of co-residence choices has implications for survey-based measurement of migration flows, for the analysis of the determinants of intra-household selection into migration, and for the effects of migration on those left behind.
