Idaho has been a refugee resettlement arena since 1975, when it was established as the Indochinese Refugee Assistance Program to help resettle refugees fleeing the overthrow of US-supported governments in South Asia. Initially, the program focused on refugees from Laos, Cambodia, and Vietnam, but it expanded to include Eastern European refugees fleeing Soviet-era regimes.

During the 1980s, most refugees settled in Idaho and Boise, in particular, were Southeast Asian and Eastern European, with many refugees from the Soviet Union arriving at the end of the 1980s particularly evangelical Christians oppressed for their religious beliefs and political dissidents.

The other half during this time came from Africa, East Asia, the Near East, Central Asia, the Caribbean, and Europe.

In the 2000s, more than 5,000 refugees have been settled around Boise, mainly refugees from Europe and Central Asia, especially from Bosnia, Afghanistan, and Russia (67%); Africa, especially Liberia, Sudan and Somalia (24%); East Asia, Latin America and the Near East (9%).
