Interviewer instructions
The actual date of birth should be entered in the boxes provided, of which there are two for the day, two for the month and four for the year. If the day is less than 10 enter a zero in the first box. The months are numbered 01 for January, 02 for February, ? 09 for September, 10 for October, ... 12 for December. For the year, enter all four digits. Thus, a birth date of 9th March, 1930 will be recorded as: 09 / 03 / 1930
If the respondent does not know the exact date, ask the question relating to the age at last birthday and write it in. Whether the actual date of birth is known or you have had to ask the age, write in the age in the box provided. For persons ninety-eight years and over write in 98 in the boxes provided. For age not stated write in 99.
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. Reference to your History Page, may be helpful. In particularly difficult cases, an estimate of the age by the respondent may be accepted, but only where more precise data cannot be obtained. In such cases make a note in the Comments Section.
