 Refugees compose about one-tenth of the total annual immigration to the United States, though some large refugee populations are very prominent.Since World War II, more refugees have found homes in the U.S. than any other nation, and more than two million refugees have arrived in the U.S. since 1980.From 2005 to 2007, approximately 40,000 refugee seekers per year were accepted into the U.S., compared to about 30,000 per year in the UK and 25,000 per year in Canada.
