The study, ILO Global Estimates on International Migrant Workers, also noted a marked increase in the number of young people seeking opportunities abroad. Often, these migrant workers carry out key roles in crucial sectors such as healthcare, transportation, services, agriculture, and food processing.  “We have seen that in a number of regions, migrant workers represent a sizeable share of the workforce,” said Manuela Tomei, Director of ILO’s Conditions of Work and Equality Department.
