The heightened global attention paid to migrants has largely bypassed South Asia, yet the problem there is as longstanding and severe as anywhere else. In this informative survey, Ghosh estimates that there are 50 million migrants, refugees, and stateless people in the region, among them populations transferred during wartime among Bangladesh, India, and Pakistan; caste and religious groups fleeing persecution; and Afghans, Chinese, Nepalese, Rohingyas, Sri Lankan Tamils, Tibetans, and others who have fled violence or repression during the past seven decades. These population movements have added to the already daunting complexity of societies in the region, intensifying political volatility and sharpening security issues. With the exception of Afghanistan, no South Asian states are party to the UN Refugee Convention. Still, compared with other regions, South Asia has treated its refugees relatively well, partly through assistance programs and partly through benign neglect. Most migrants have gotten jobs, and many have even become citizens of their countries of refuge.
