Since you will be interviewing in general one member of any household, the ethnic group ticked must be the ethnic group to which the respondent says he and other members belong. It is reasonable to classify all children of parents belonging to different ethnic groups as mixed. For example, if a man of African descent is married or living common law with an East Indian woman, their children should be classified as mixed.

Accept the respondent's classification. If you think you are being misled make a note in an appropriate part of the questionnaire and inform your supervisor.
