The paper assesses, in a systematic way, the availability and quality of migration and mobility data in Europe, with a focus on bilateral migration flows based on the official statistics reported by the Eurostat. First, using real examples from specific countries, the paper discusses general data availability and comparability issues, including definitions, undercounting, coverage, and accuracy. Second, a thorough analysis of available metadata reported by national and international data repositories is performed in order to understand specifics of migration data collected by national statistical bodies. The study concludes that available metadata is often incomplete, imprecise, or even missing. The observed inaccuracies in migration statistics and lacking metadata may lead to wrong evidence for policymaking and should be taken into account in specific statistical models that estimate actual migration flows. The study lays the foundations for the Human Migration Database project, which aims at producing internationally comparable migration estimates on the basis of rigorous data quality assessment and advanced statistical framework.
