The labor status of Central American migrants is characterized by precarious work. This applies to both Guatemalans with temporary work permits who return to their country after a stay in Mexico as well as Guatemalans, Salvadorans and Hondurans living permanently in Mexico. This report is based on Mexico’s Southern Border Migration Survey (Emif Sur) 2004-2013 (Encuesta sobre Migración en la Frontera Sur de México) and the housing and population censuses from 2000 and 2010.
