Interviewer instructions
There may be instances, especially in the case of older people, where a respondent may not remember their age or the exact age of the person to whom you are referring. Since a 'not stated' or 'not known' answer or a blank is NOT ACCEPTABLE and would require that you pay another visit to the household, you may need to probe to find out the correct answer or to ask the question directly to the person for whom you require information. Referring to your History Page, may be helpful. In particularly difficult cases, an estimate of the age by the respondent is accepted, but only where more precise data cannot be obtained. If age was estimated insert an X in the box provided.
