Interviewer instructions
<svar a="all" v="BR91A414 BR91A415 BR91A416"><span class="h3">Question 6 - Month and year of birth</span><br />Record the person's month and year of birth. Do not record the day of birth. When the number of the month of birth is less than 10, complete with a zero to the left. The year of birth will be recorded with three digits; for example: 940 and not 1940 or 40; 899 and not 1899 or 99.<br /><span class="pg">[p. 59]</span><br />For persons who only know their day and/or month of birth, without remembering the year, the year cannot be calculated based on the information regarding presumed age.<br />This question will remain blank when the person is unable to state the month and year of birth.<br /><span class="h3">Question 7 - Presumed age</span><br />This question will only be filled out when the respondent does not know his or her month and year of birth. Presumed age will only be recorded after all efforts at obtaining the month and year of birth have been exhausted.<br />If the age is 1 year or older, record the full number of months years in One Year or Older Field. When the presumed age is insufficient to fill in the fields reserved for this record, complete with zero(s) to the left.<br />If the age is less than 1 year, record the number of full months in the Less Than 1 Year Field. When the number of months is less than 10, complete with one zero to the left. For newborn children less than 1 month old, if it is not possible to inform the month and year of birth, record 00.<br />Note that the entry of the presumed age for children under the age of 1 should be very rare and admissible only in exceptional cases.<br /></svar>
