Inadequate data on international migration poses challenges for accurate measurement and policy-making. The UK’s Migration Research Unit at University College London highlights urgent needs and potential solutions for reliable and comparable data. The Labour Market Statistics User Group Meeting on January 23, 2009, emphasized the scarcity of data, despite the importance of understanding foreign nationals' employment trends from 1994 to 2008 and the flows of international migrants. It is essential to enhance data collection methods for effective labor market planning and resource allocation.

Data on international migration are generally considered scarce and inadequate for measurement purposes (IUSSP, 1987). An urgent need for international migration statistics coincides with an unsatisfactory degree of availability, reliability and comparability of data on international migration flows (THESIM, 2006).
