5. At present, what is solar calendar age of [the respondent]?

Part 1: Information about members of the household
Part 1 of the Census form consists of 41 questions, numbered sequentially from Question 1 to Question 41.

The respondent is the head of the household or a person knowledgeable about members of the household. For information on employment and birth history of women, DTV needs to interview DTDT face-to-face and collect information. In addition, for other information about members of the household, if the head of the household or the information provider is not knowledgeable, DTV also needs to interview DTDT face-to-face and record the information.

Question 5: How old is [the respondent] now according to the solar calendar?
This question is only asked and recorded for people who cannot remember the year of birth in order to collect information about the rounded solar age of DTDT. Therefore, when DTDT answers about their age, DTV has to ask "Is it the lunar or solar age?" If DTDT answers the lunar age, DTV must subtract 1 to get the solar age and write the information in the box.

When DTDT cannot remember their age, DTV can refer to relevant records and documents or discusses further with other members of the household to record the age or probe to estimate the age. It is possible to probe by comparing the age of DTDT with the age of someone in the household or the age of the people around whose exact age is known.

If the age probing measures do not work, DTV must estimate the age of DTDT by observing DTDT, that is observing the appearance of DTDT combined with the age of DTDT's children, spouse, etc. to estimate the approximate age for DTDT. Please note, this is the last viable option, only implemented when all attempts to probe the age do not work. Do not leave a blank in this question.
