Notes: The QuantMig Migration Estimates Explorer provides harmonised probabilistic estimates of migration flows among 32 countries in the European Union (EU), the United Kingdom, the European Free Trade Association (EFTA), and North Macedonia, as well as to and from the rest of the world, based on publicly-available Eurostat data. All estimates also include selected measures of uncertainty. The estimated migration flows relate to long-term migrants (for 12 months or longer), as defined in the EC Regulation 862/2007 on migration and asylum statistics. The estimates update and expand the ones created in the project Integrated Modelling of European Migration (IMEM), funded in 2009-12 by NORFACE.

Estimated flows can be presented by country of origin, country of destination, age, sex, and the region of birth, for years 2009 to 2019, also including the original IMEM estimates for 2002 to 2008. The legacy IMEM data are also available at, and the IMEM methodology is described in: J Raymer, A Wisniowski, JJ Forster, PWF Smith and J Bijak (2013) Integrated Modelling of European Migration. Journal of the American Statistical Association, 108(503), 801-819 (DOI: 10.1080/01621459.2013.789435).
