African Immigration in the United States and Washington.  Africans in the United States come from different national, linguistic, ethnic, racial, cultural and social backgrounds. The influx of African immigrants began in the latter part of the 20th century, and is often referred to as the fourth great migration. About three-fourths of all out-migration from Africa after 1990 went to the United States. Between 2010 and 2015, the number of African immigrants in America more than doubled, rising from approximately 723,000 people to more than 1.7 million. African immigrants are among the most educated groups in the United States. Approximately 40 percent of all African immigrants hold a college diploma. Of this group, over 34 percent have degrees in science, technology, engineering, or mathematics.

As of 2019, there are 78,669 African-born immigrants living in Washington State. The University of Washington indicates as of 2018, the largest African-immigrant populations in Washington were born in Ethiopia, Kenya, Somalia, Eritrea, Gambia, South Africa, Egypt, Nigeria, and Ghana. The 78,669 African-born immigrants in Washington represent over 35 countries of birth and live in communities across the state. There is a high concentration of African immigrants in King County in particular, with King County ranking eighth among United States counties for the highest total immigrant populations from Africa.
