Interviewer instructions
The interviewer should prompt the respondent to assess the ages of these
people and record the three main age groups. If the respondent answers with an age group
that doesn’t fit with the ones provided in the questionnaire, such as from 20 to 30; in this
case the interview must ask further to see if they are mainly from 20 to 24 or from 25 to
30 so the interviewer can decide whether to put these people in group 15-24 or 25-30
