For everyone:
1. How old is the person (in completed years)? (PerNa01)
Age _ _ _
Note the age in completed years at the date of the interview. As the response should be noted in completed years, for those less than one year, 00 is noted.
If you believe the age declared does not seem correct, signal that it is very important for the census that the ages of the people are found to be very precise.
If the informant does not remember the age of some member of the household, ask him/her to remember some event (marriage, the birth of a child, year in school, among others) or that he/she consults some document (identification, driver's license, etc. where the date of birth is found in order to calculate the age.
