Interviewer instructions
If the respondent were not sure of his age, please try to find more information about his age using the following manners:
1. Birth certificate, birth affidavit, doctor's card, immunization card, Road to Health Card (KMS) or other notes or other records made by his parents. Note the date of issuance of the documents (e.g. ID Card or Family Card); if it stated the age (not the date of birth).
2. Connect the respondent's date of birth with the date, month, and year of an event in Indonesia or in the region which is wellknown nationally or regionally.
Example:
National election, volcano eruption, flood, fire, regional election, etc. Several other important event that can be used to estimate the age of a respondent are among others:
a. Japanese troops landing in Indonesia (1942)
b. The proclamation of the Independence of Indonesia (1945)
c. The First National Election (1955)
d. The Rebellion og G30S/PKI (Indonesian Communist Party) (1965)
3. Compare household members age between siblings. Start with estimating the age of the youngest child, then compare him/her with the second youngest child by asking how old he/she is or asking the things he/she could do [sitting (6 months), crawling (8 months), standing (9 months), walking (12 months)] while his younger brother/sister was born or started being in the womb. Do the above method to get information on the older children.
4. Compare the respondent with the neighbor's child or sibling whose age has been confirmed. Make an estimation on how many months older or younger the respondent is in comparison with those other children.
Is not uncommon for a respondent to say they do not know their age and when asked about his/her age, the answer is " up to you, Sir/Madam". In such cases, enumerators shall be required to ask again with more patience, to repeat all methods suggested.
