Forced migration or displacement
In studying forced or involuntary migration—sometimes referred to as forced or involuntary displacement—a distinction is often made between conflict-induced and disaster-induced displacement. Displacement induced by conflict is typically referred to as caused by humans, whereas natural causes typically underlay displacement caused by disasters. The definitions of these concepts are useful, but the lines between them may be blurred in practice because conflicts may arise due to disputes over natural resources and human activity may trigger natural disasters such as landslides. Countries faced with forced displacement—induced by humans or nature—collect data on displaced populations. Such data are typically collected through a combination of population censuses, household surveys, border counts, administrative records and beneficiary registers. At the international level, data on forced migration are collected and/or compiled by various intergovernmental organizations (IGOs), such as the Office of the United Nations High Commissioner for Refugees (UNHCR) and the International Organization for Migration (IOM), as well as non-governmental organizations (NGOs), such as the Internal Displacement Monitoring Centre (IDMC).
The G20 and migration
The G20 countries are at the centre of not only global economic governance, but also global migration governance. They play a leading role as their policy responses to migration challenges and opportunities affect migrants, countries of origin, transit and destination, and the world economy. Data on G20 countries show the extent to which migration affects the G20’s demographic and socioeconomic spheres, but data limitations hamper more robust research that could allow policymakers to fully harness the economic potential of migration and formulate policies to promote safe, orderly and regular migration. In light of the 2030 Sustainable Development Agenda and the Global Compact for Safe, Orderly and Regular Migration, G20 leadership on more comprehensive, timely, and comparable migration data is essential.
