Interviewer instructions
<span class="h1">6.5 Section VII. Sociodemographic characteristics</span>
<br />In this section, the sociodemographic information of the members of the household in the selected home is obtained. The type of information collected varies based on the different age groups and sex of the people subject to the study, as shown on the following chart:</p>
<p>[Omitted figure]</p>
<p>The preceding topic can be seen on the back of the sociodemographic questionnaire, that is, in the next image:</p>
<p>[Omitted figure]</p>
<p><span class="em">Question 9</span>
<br />The purpose of this question is to learn the age of the people in years completed at the time of the interview.
<br />[Omitted figure]</p>
<p>Instructions:</p>
<div class="i1">- Distinction in the use of the columns. In column 9, enter the age obtained in the first interview; column 9a is used to update it when the person has had another birthday in any interview from the second to the fifth.<br />- How to record the information. In the case of children under one year old, enter two zeros; if the person is 97 years of age or older, enter 97.<br />- Age unknown. If the informant does not know or remember the exact age of any member of the household, help them calculate it by asking them to tell you about any event that could be important to them: the date of their marriage, the birth of a child, etc.<br />If, despite the foregoing, the informant insists they do not know the exact age of any member of the household, ask if they have the birth certificate, voter identification card, driver's license or another document on hand that could contain the date to determine the age; if that is not possible, enter code 98 in the case of people 12 or older, and 99 in the case of children younger than that age.<br />- Recording the same age for two or more people. When the age of two or more siblings is the same because they are from a multiple birth (twins, triplets), specify the situation in the Comments section.<br />- Sequence to follow. Regardless of the response, continue with question 10.</div>
