In 2010, more than 200 million
people—about 3 percent of the world’s
population—lived in a country different
from the one in which they were born,
and internal migration within countries
continues at high levels.2 International
migrants, who may move permanently
or temporarily to another country, are
equally likely to be men or women.3
About 10 percent of the population of
developed countries is comprised of
international migrants, who commonly
migrate for economic reasons. Less than
10 percent of international migrants are
refugees from conflict.4
