The ILMS Database is the first of its kind in ASEAN. It provides a coherent and powerful research tool for policymakers and others to profile and monitor the international migrant labour force within the region. The database, created by the Canadian Government-funded ASEAN TRIANGLE Project, gathers together a range of statistical sources relating to international migrants and international migrant workers in the ten ASEAN Member States in order to fill an important knowledge gap. It comes at a critical time for ASEAN as it reaches a major milestone – the creation of the ASEAN Community in 2015. In order to manage and understand international labour migration trends more coherently, the ILMS Database collected relevant, comparable and tractable data, including from a range of previously unpublished sources. The data includes countries' stocks of international migrants and international migrant workers; the corresponding annual inflows of these; and countries' stocks and outflows of nationals abroad.
