The Jarai (also Gia Rai, or Gia-rai) originate from Vietnam's Central Highlands. Their language is related to the Cham language of central Vietnam and the Malayo-Polynesian languages of Indonesia, Malaysia, Madagascar, Philippines and other Pacific Islands (Hawaii, New Zealand, Easter Island, Samoa, Guam, Fiji, etc.). In Vietnam, they are the largest of the upland people group of the Central Highlands known as Dega or Montagnards.
Following the Vietnam War, many Jarai (as well as members of other Montagnard groups) who had been allied with the United States were resettled with their families in the United States, particularly in the state of North Carolina. Along with the Jarai people, the Bahnar, Koho, Bunong, and Rhade people, all Vietnamese Central Highlands people groups, reside in North Carolina.
The Montagnard population in the North Carolina of the various people groups is about 10,000. Most live in Raleigh, Greensboro, and Charlotte.
