Description of people as being of a regional descent (eg, of African, Asian, European, or Middle Eastern or North African descent) is acceptable if those terms were used in formal research. However, it is preferable to identify a specific country or region of origin when known and pertinent to the study.
For example, describe persons of Asian ancestry according to their country or regional area of origin (eg, Cambodian, Chinese, Indian, Japanese, Korean, Sri Lankan, East Asian, Southeast Asian). Similarly, individuals from the Middle Eastern and North African region should be described using their nation of origin (eg, Egyptian, Iranian, Iraqi, Israeli, Lebanese) when possible.
For individuals of various ancestries living in the US, do not reflexively add "American." However, there are times it is appropriate. For example, individuals of Middle Eastern and North African descent who identify with Arab ancestry and reside in the US may be referred to as Arab American. Similar construction would apply for other groups such as Asian American, Indian American, etc.
