Age
Column 2
Never fail to write an answer to this question.
[Drawing] Write down the age of the person in attained years for persons older than one year, that is, the number of years they completed on their last birthday.
[Drawing] For children less than one year old, obtain the age in attained months.
[P. 33]
In the case of children less than 1 month old, mark the corresponding circle with an X.
If the exact age is not known, as occurs for some older people, ask: "What year were you born?" If that date cannot be obtained either, try to associate the age which they had at the time of an important occurrence. For example: the beginning of the Revolution of 1910, the Expropriation of the Petroleum Industry in 1938, etc.
