Q. 9 Date of birth
56. For each person the enumerator will record the exact date of birth: the year, month, day, written in Arabic figures using, in all cases, a two-digit Arabic number. For months and days between 1 and 9, first digit of each number will be "0" (01,02...09).
For persons who do not remember the exact year, month and day of their birth, the enumerator will ask other members of the household or check the identification card or birth certificate. When neither of these documents is available (as for aged persons), additional questions will be asked to indirectly find the birth date, or at least the year of birth (using temporal reference points - such as the 1907 hostilities or the participation of Romania in WWI, etc. - and the relative age of the person at the moment of the event).
