Definition
This question asks ethnic majority in sampling area where it is important to find out about ethnic diversity in the area. Ethnicity must be asked to respondent and must follow respondent's response. A respondent lives in Java doesn't have to be a Javanese, or people in North Sumatera is not always a Batak. In a case where respondent's parents come from 2 different ethnics, we must rely on respondent's response; enumerator must not generate answer from his/her own observation.
