1. Data on legal immigrants and temporary workers come from the Department of Homeland Security Office of Immigration Statistics. The remainder of the figures used in this article, including the net inflow of illegal migrants, comes from data gathered by the Mexican Migration Project of Princeton University, which I codirect. Migration histories compiled on thousands of migrants interviewed in annual surveys since 1982 enable me to estimate the likelihood of a migrant leaving Mexico on a first undocumented trip and returning within twelve months, which, when applied to population data from the Mexican census, yield reliable estimates of net annual undocumented migration.
