Interviewer instructions
Person’s age is required here.
There may be instances, especially in the case of old people, where a respondent does not remember his/her 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 to see the person himself/herself.
