Measuring international migration in Asia

ABSTRACT The benefits of having consistent and complete information on migration flows within, from and to Asia are numerous and worth the investment. They include a much better understanding of how migrants are responding to economic developments across Asia and how they are transforming both origin and destination societies. The challenges to producing international migration flow statistics in Asia, however, are immense. Hardly any countries provide data, and for those countries that do, they are often incomplete or incomparable with other countries' measures of migration. In order to produce comparable statistics on migration flows and immigrant population stocks, one needs a range of data sources and estimation strategies.
