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.

摘要

拥有关于亚洲内部、来自和流向亚洲的移民流动的一致和完整信息的好处很多，值得投资。它们包括更好地了解移民如何应对整个亚洲的经济发展，以及他们如何改变原籍国和目的地社会。然而，在亚洲制作国际移民流动统计数据的挑战是巨大的。几乎没有任何国家提供数据，对于那些提供数据的国家，它们通常是不完整的或与其他国家的移民措施无法比较。为了生成关于移民流量和移民人口存量的可比较统计数据，需要一系列数据源和估算策略。
