Rapid aging of both wealthy and middle-income countries will make their economies increasingly dependent on migration from poorer countries, and the process needs to be better managed, the World Bank said on Tuesday.
The bank's latest World Development Report said that about 184 million people across the world now live in countries where they lack citizenship, 43% in low- and middle-income countries. About 37 million of the total are refugees, a number that has tripled over the last decade.
