The MMP is a multidisciplinary research effort between investigators in Mexico and the United States. Each year, during the winter months (when seasonal migrants are home), the Mexican Migration Project randomly samples households in communities located throughout Mexico. After gathering social, demographic, and economic information on the household and its members, interviewers collect basic information on each person's first and last trip to the United States. From household heads, they compile a year-by-year history of U.S. migration and administer a detailed series of questions about the last trip northward, focusing on employment, earnings, and use of U.S. social services. |
