Asian-born residents comprised 27 percent of the country's foreign-born population in 1997, not significantly different from 1990 when they comprised 26 percent. Their share doubled from 9 percent in 1970 to 19 percent in 1980. In 1997, the five largest contributors to the nation's Asian-born population were China, India, Korea, the Philippines and Vietnam.1 For all but Korea, the number of people hailing from each nation rose significantly from 1990 to 1997."
