B05. B06. Date of birth and Age
The date of birth allows one to compute the age of the persons, and is therefore a very important piece of information of the census. You must therefore do your best in order to obtain precise information on this matter. Two cases can be found:
1st case: For all persons who have a birth certificate or an identity card with a complete date of birth, ask whether this date is from a proper birth registration or whether it is based on a court decision [jugement supplétif].
If this is a formal birth registration, register the month number (two digits) in the boxes under which is written month, and year of birth in the boxes under which is written year.
[A birth date example from the original was omitted]
Remarks: if the month and the year of birth are unknown, leave the boxes blank, and go to the next question.
When this is a court decision, estimate by yourself his or her age with the help of the historical calendar, or with any other method for checking ages (age at first marriage, comparison with other persons of the same age, age of the first child for instance).
When the person does not have any birth certificate or ID card: then estimate his or her age as rigorously as possible, with the help of the historical calendar and of any other means of estimation, and write the estimated age in the "age" box; for persons aged 98 years and above, write "98".
Note: For children under five years of age, do accept the birth certificates and possibly the health cards.
