6. Birth Date:

Write the birth date in column 6 for persons in the household who have an official document related to their birth date. Then write it converted into completed years in column 7, as indicated in the example below.

[Page 25]

Practical example: The birth date of a person born on August 22, 1968 is indicated as shown in this table.

Date of birth (month/year): 08/68 [_]
Age: 18 y [_ _ _]
Take the following documents into consideration when recording a birth date:
- Birth certificate
- Baptism certificate


Other documents, such as remedial orders, I.D. cards, family booklets, passports, etc... should not be considered unless they show at least the month and year of the individual's birth. If the documents don't have the year of birth, fill out only the AGE column. Convert the year of birth into completed years before writing it in column 7.

Example: A certain individual's ID card has written on it: BORN AROUND 1940, without any additional detail about the day and month of birth. In this case determine the age of the individual by subtracting 1987 from 1940, which equals 47 years. Write this age in column 7 and write a dash or hyphen (-) in column 6.
