Interviewer instructions
<svar a="all" v="CN90A403 CN90A404 CN90A422">4. <span class="em">Age</span> -- Fill in the age, month and year of birth. For age, only count the number of full years from birthday to the standard time of Census. For those less than one year old, fill in "0". If there is an elderly in the household who is a hundred years old, fill in the "Remark" that this person is a hundred years old. Birth date is by the Gregorian calendar. Convert the birth date into the form of Gregorian calendar if the birth date is remembered in the form of Chinese calendar; the conversion should follow the cross-list of age in the appendix. As a rule of thumb, the difference between the month in the lunar calendar and that in the Gregorian one is about one month. When converting the lunar calendar to Gregorian one, enumerator can just add one to the birth date. Just need to pay attention that Dec in the lunar calendar is January the following year in Gregorian calendar.<br /><br />Fill in the month and year of birth date and age in Arabic numerals.<br /></svar>
