Statistics on migrant workers

Table of Contents

In today’s globalized world, labour migration is an increasingly important policy issue. Economic hardship and geopolitical crises leading to the lack of decent work are resulting in growing and diverse migratory movements. In many economies, including emerging economies, ageing populations and declining labour forces are also contributing to the growing mobility of workers. Women are joining migration flows in growing numbers as independent workers, with important consequences for gender equality in countries of origin and destination alike.

We need to understand these dynamic migrant flows and their implications for labour markets, particularly in migrant-dominated sectors.

This page presents statistical information on migrant worker stocks, inflows and outflows.

SDGs and labour migration

The 2030 Sustainable Development Agenda Declaration in its paragraph 29 states that: “We recognize the positive contribution of migrants for inclusive growth and sustainable development. We also recognize that international migration is a multi-dimensional reality of major relevance for the development of countries of origin, transit and destination, which requires coherent and comprehensive responses. We will cooperate internationally to ensure safe, orderly and regular migration involving full respect for human rights and the humane treatment of migrants regardless of migration status, of refugees and of displaced persons.” This objective is further concretized in SDG target 8.8: “Protect labour rights and promote safe and secure working environments for all workers, including migrant workers, in particular women migrants, and those in precarious employment” and in SDG target 10.7: “Facilitate orderly, safe, regular and responsible migration and mobility of people, including through the implementation of planned and well-managed migration policies”, which both clearly relate to ILO’s mandate as articulated most recently in the fair migration agenda. 

The ILO is the custodian agency for further developing the methodology for two of the SDG target 8.8 indicators concerning occupational safety and health and freedom of association and collective bargaining, both to be disaggregated by sex and migrant status. Together with the World Bank, the ILO is also collecting data and developing a methodology to measure the cost of recruitment, which is one of the indicators under SDG target 10.7.

Use the search box to enter key words; use quotes around your term for better results. Available filters differ depending on the catalogue. Selecting a frequency allows users to find monthly, quarterly, or annual indicators. While all indicators are available for annual periods, only a subset are available as monthly or quarterly. 

Options to access data

This tool provides an intuitive interface to filter the selection, pivot the table, calculate distributions and growth rates, and export data into various formats.

Data available in the Excel summary files are for indicators only (not available for countries or regions) for selected classification items for 2010 onward for annual data and 2018 onward for short-term indicators. For historical data or additional classifications, either use the Data Explorer or download the CSV file. 

Available in the country catalogue only, this option takes users to the country profiles page with the selected country pre-filtered in the table. Highlighting the latest year available for key indicators, this is a subset of the available data for a given country.
