Question 29. How old is [the respondent]?
The age refers to the years of age a person has lived until the present date from his/her date of birth. Ask the interviewee how old he/she is and then record the declared age in the boxes corresponding to the answer. If the person is less than one year old record '000' in the boxes.
If you have already questioned and attempted to help the person remember his/her age, and there is no way to establish the age of that person or any other member of the household, then you should record code 999.
