UVA researchers say the state’s foreign-born population is growing and now comprises 15% of the Virginia workforce. The UVA Weldon Cooper Center says one in nine Virginia residents was born outside the U.S. compared to one in 100 back in 1970. El Salvador is the top country of birth for immigrants to Virginia followed by India, Mexico, the Philippines and South Korea. The Northern Virginia metropolitan area is home to almost 70% of Virginia’s foreign-born population. Researchers say almost 20% of children born in Virginia have at least one foreign-born parent.
