4. Age: How old is [the respondent]?

15.2 Section II. List of people and general data
The section is made up of questions that allow us to know the number of people who are habitual residents of the housing unit, and in addition, to record the gender, age, and relationship of each person with respect to the head of the housing unit.

Remember that it is very important to record all the residents of the housing unit since the 2020 Population and Housing Census must count all the people living in the country.

4. Age
This question helps to find out how old the residents of the housing unit are at the time of the interview. In addition, it allows to apply the age cutoffs of the questionnaire. Read the question for each person, listen to the answer, and record the age in the space provided.

If the respondent does not remember or does not know the age of a person, support them by mentioning an event, such as a marriage, the birth of a child, school year, among others, or ask them to consult the birth certificate, voter's credential, CURP, driver's license or other documents where the date of birth appears; help them to calculate the age.

When the respondent says phrases such as "33 in the age of 34", "2 and a half" or "almost 5", rectify with them the age in years completed at that moment (the correct answer in these cases is: 33, 2 and 4, respectively). Enter three zeros (000) if the person is younger than one year old, whether it is hours, days, weeks, or younger than 12 months old.
