Putting the Pieces of the Puzzle Together: Age and Sex-Specific Estimates of Migration amongst Countries in the EU/EFTA, 2002–2007
Because of inconsistencies in the reported migration flows and large amounts of missing data, our knowledge of international migration patterns in the Europe is limited. Methods for overcoming data obstacles and harmonising international migration data, however, are improving. In this article, we provide a methodology for integrating various pieces of incomplete information together, including a partial set of harmonised migration flows, to estimate a complete set of migration flows by origin, destination, age and sex for the 31 countries in the European Union and European Free Trade Association from 2002 to 2007. The results represent a synthetic data base that can be used to inform population projections, policy decisions and migration theory.
