Data from the Latin American Migration Project (LAMP) and the Mexican Migration Project (MMP) is combined to analyze migration patterns for Mexico, Puerto Rico, the Dominican Republic, Nicaragua, and Costa Rica. Drawing on samples of 31 communities, we document the frequency and timing of migration, the date, duration, destination, and documentation of the first and the most recent U.S. trips, the employment characteristics of migrants on those trips, and migrants' socioeconomic characteristics and selectivity. Results show that a significant share of the migration is unauthorized. The distinctive features separating Mexican migration from other flows are its concentration in farm labor, lack of educational selectivity, more frequent trips, and shorter durations of stay. All groups are showing a pronounced tendency to settle away from traditional destination areas. The analysis suggests a commonality of basic patterns and processes of migration structured and expressed in distinct ways according to context. This analysis shows that data from the LAMP and the MMP can be combined effectively to undertake comparative quantitative studies
