37. The date of birth:
Recorded in this field in numbers the date of birth of the person by day, month and year. The numerator has to notice that number (19) is fixed on the field of year means thousands and hundreds. If the person was born in 1945 it is recorded beside number (19) number (45). The numerator has to regard and to work hard in collecting these data accurately especially children and the year of birth and if the name of the month is not available he has to confirm the year of birth only. He does not have to mention the age in years but only does the year of birth. To ensure the accuracy of data he has to go back to the documents available to fix the data of birth and it depends first on the birth certificate then the identification card and if it is not available he depends on army service certificate or nationality certificate or passport and if all these documents are not the same and there is some difference in them the numerator has to estimate the year of birth on the basis of the person appearance and the rest person of the household opinion and to connect the year of birth with national, religious and historical events and the ages of the rest persons of a household.
[p.12]
Note: If the date of birth in the identification card includes (1/7) in day and month the numerator has to ask the person about the real date of his birth although the day and month (1/7) is available in his identification card. If it is obvious that the person really doesn't know the day and month of his birth the numerator doesn't have to record that and to record the year of birth only.
