Questions 1 [order number] to 12 [residency status] apply to all persons to count in the household.

5. Date of birth

The date of birth of an individual indicates the day, month, and year of the birth. There are individuals who know their exact date of birth. There are those who do not know the complete date of birth but could at least recognize the month and year of their birth.

To gather information relative to an individual's date of birth, proceed as follows by asking the following question: [Q]: "Do you know the exact month and year of your birth?" If the answer is "yes," ask the interviewed person to tell you the month and year of their birth and register this answer in the appropriate boxes:

Example: for a person born in October 1970,
Write down 10 in the two upper boxes [month] and 1970 in the four lower boxes [year].
Calculate the age and write it in the boxes reserved to this effect in column 6.

If the person does not know their date of birth, ask if they possess a civil status document, and identification card, a passport, a driver's license, or any other official document that could indicate the date of birth. If the answer is "yes," ask them to produce the document and use it to report the month and year of birth in the appropriate boxes.

In the case where the person only knows their year of birth, write down the year in the appropriate boxes and write down "98" in the boxes reserved for the month.

If the person does not know their date of birth and has no document that can provide information on the date of birth, in this case, ask if they have an idea on their age. If the answer "yes," write down their age in the boxes reserved to age transcription in question 6, then calculate the date of birth as the difference between the observation date and the age of this person. Then write down "98" in the boxes reserved to the transcription of the month of birth.
