1. Persons in the household: Who was a member of this household on September 26, 1994?
If there are more than 10 members in the household, use additional questionnaire(s). When this is necessary, tick the box in the bottom right corner and change the person number (1, 2, 3 ... in column a in the questionnaire) to 11, 12, 13 ... in the second questionnaire, 21, 22, 23 ... in the third questionnaire, etc.
Regarding the routines for collective households, see the enumerator's manual.
4. How old was [the respondent] at his/her last birthday?
Question 4: How old was [the respondent] at his/her last birthday?
Age is one of the most important questions as much analysis of data depends on respondent's age, for example, fertility rates are calculated by age of woman etc. Age also determines whether certain questions are to be answered or not. Be careful not to round ages up to the next birthday.
Entries should be made in completed years as follows:
If the age is not known, probe to try to estimate age. This is time-consuming and sometimes tedious. But it is important to take time to try to get the best possible information. There are several ways which can be used to probe for age:
You may use the calendar of events found in Appendix 3 to improve the reporting of age data. A person's age can sometimes be better assessed in relation to events which he/she can recall or which occurred near to his/her birthday. The age of the person's relatives is sometimes a useful indicator.'
If probing does not help, you may have to estimate the age as a last resort when all other efforts failed. The use of the code "999" (viz. not known) is for rare cases.
In case the respondent knows the year when he/she was born only in Lao year or lunar calendar, or he/she gives date of birth in solar calendar, you must refer to tables for age conversion in the Appendix 4 of this manual.
