Attention: Note the month and year of birth (Question 4.05) and the age on 31 July 2000 (Question 4.06). If it is not possible to obtain the month and year, after exhausting all possibilities, note the presumed age (Question 4.07) in years (if the age is greater than or equal to 1 year), or in months (if the age is less than one year), leaving questions 4.05 and 4.06 blank.

4.05 Month and year birth

4.06 Age on July 31, 20004.07 Presumed age

Question 4.05 (Sample) and 4.03 (Basic) - What month and year were you born in?

Record the month and, with four digits, the year of the person's birth.

For persons who know only the day and/or month, without remembering their year of birth, the year cannot be calculated based on the information of presumed age. This question will be left blank when the person is unable to inform the month and year of birth.

The month should not be completed with zeros in this question.

Question 4.06 (Sample) and 4.04 (Basic) - How old were you on July 31, 2000?

This question should be filled out only for those who also filled out Question 4.05 (month and year of birth).
If the age is one (1) year or over, record the number of full years in the Field: 1 year or more.
If the age is less than one (1) year, record the number of full months in the Field: In months.
For recently born children less than one (1) month of age, record 0 (zero) in the Field in months.

This question should not be completed with zeros.

Question 4.07 (Sample) and 4.05 (Basic) - What is your presumed age?

This question will be filled out only when the respondent does not know his or her month or year of birth. Presumed age should be recorded only after all efforts at obtaining the month and year of birth have been exhausted.

If the presumed age is one (1) year or over, record the number of full years in the Field: 1 year or more.
If the presumed age is less than one (1) year, record the number of full months in the Field: In months.
For recently born children less than one (1) month of age, record 0 (zero).
The entry of presumed age for children under one (1) year should be very rare, and admissible only in exceptional cases.

This question should not be completed with zeros.

From Question 4.08 until Question 4.27, only the data for CD 1.02 - Sample Questionnaire - will be investigated.
