About 251,000 Ethiopian immigrants and their offspring (first and second generations) reside in the country, making up 0.5% of all immigrants who were born outside of the United States. In recent decades, the number of Americans born in Ethiopia has rapidly increased from a tiny base; in 1980, there were roughly 10,000 Ethiopian immigrants living in the US. Ethiopian immigrants are currently the second-largest African immigrant group in the United States, behind Nigerian immigrants.
Ethiopians are the most recently settled of the 15 groups studied by the Rockefeller Foundation-Aspen Institute Diaspora Program (RAD), with 60% of their immigrants arriving in the United States in 2000 or later. Despite having only recently arrived in the country, approximately half of all immigrants from Ethiopia are citizens.
