Interviewer instructions
I. For all persons. General characteristics
Question 4. What is the attained age?
Write the age on the line for "attained age."
[A drawing of people and depiction of question 3 is omitted here.]
[P. 39]
If the person giving the information does not know their age help them in some of the following ways:
Ask some of the other members of the household about their age.
Ask for their birth years and make the corresponding calculation. If they say that they were born in 1932, they will be 50 years old (1982-1932 = 50 years). Ask them for a personal identification document (I.D. card, baja [dismissal], election card, proof of conscription, etc.) or deduce their age, in the way done in the previous example.
By making a relation to certain historic, national, local or family events, such as: their age at the time of the revolution of 47, age when they were married and how many years of marriage they have, age when their oldest child was born and the actual age of that person, etc.
If it impossible to determine their age through these resources, estimate the age by simple observation.
