In 2018, the journal Ensayos de Economía published a study by Méndez Delgado, Sánchez Mena and Castro Lugo on how people in Mexico find work. It used data from INEGI’s national employment survey, ENOE, for late 2016 and early 2017.
“El 43.5% de los ocupados encontraron trabajo a través de algún familiar o conocido” (43.5 percent of the employed found work through a relative or acquaintance). The figure refers to the employed people in the study’s sample.
