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.
Family is a major driver of migration. Family migration is the term used to categorize the migration of people who migrate due to new or established family ties, and it encompasses several sub-categories: reunification with a family member who migrated earlier (a person with subsidiary protection is also entitled to (re)unite with family members); family accompanying a principal migrant; marriage between an immigrant and a citizen; marriage between an immigrant and a foreigner living abroad; and international adoptions. In general, data on family migration are sparse and family (re)unification programmes are the predominant means to collect such data. These programmes were developed to ensure the right to a family enshrined in Article 16 of the Universal Declaration on Human Rights. Data on family migration are based on visas and residence permits issued to family members, as well as population registers.
Household surveys: A key potential source of data on migration
For most countries in the world, the most common existing data sources to collect data on international migration are population censuses and other traditional sources such as administrative records. Dr. Richard E. Bilsborrow, Professor at the University of North Carolina at Chapel Hill, explains the limitations of these data sources and explores the potential existing household surveys hold for future data collection. (This is part 1 of a blog on household and specialized surveys for collecting migration data. Part 2 is available here.)
