The Relationship with the reference person is not a direct question in the questionnaire but goes through a very complex calculation process (prior selection of a standardised reference person that is always the same in two similar households, in particular), therefore, in a small percentage of cases (irrelevant from a statistical point of view), it may have been allocated incorrectly.
