Ethnicity Only citizens of Mongolia should answer this question. Those with foreign citizenship and non-relationship should not respond to this question. On the basis of respondent's answer, the enumerator should record the ethnicity of that person. The ethnicity of children will be defined by their parents. If they cannot define the ethnicity, then the ethnicity of children will be recorded as the mother's. Code 01 is for category "Khalkh" so this will be circled for "Khalkh" ethnicity. See annex 3 for other category of ethnicity. Enumerators should correctly explain that "Khalkh" is the only distinguished ethnicity in the census questionnaire to facilitate the enumerators' job, not to disregard other ethnicities. This is because around 80 percent of total population of Mongolia are Khalkh people.
