Martin, Philip (2009). "Migration in the Asia-Pacific Region: Trends, factors, impacts" United Nations Development Programme, Human Development Reports Research Paper 2009/32 United Nations Development Programme pp. 1-89

This paper provides a comprehensive assessment of international migration in the Asia-Pacific region and reviews internal migration in China. After putting Asia-Pacific migration in a global context, it reviews trends in migration and the impacts of migrants in the major migrantreceiving countries, patterns of migration and their development impacts in migrant-sending countries, the human development impacts of migration, and three policy issues, viz, new seasonal worker programs for Pacific Islanders in New Zealand and Australia, required local sponsorship of foreigners in the Gulf countries, and the economic effects of migrants in the US and Thailand. Recent trends in internal migration in China, which shares attributes of international migration because of the hukou (household registration) system, are also assessed.
