Interviewer instructions
16. Age (at last birthday), Column 10
Write down the individuals' age in two digit numbers. In this case, age means the number of full years passed from the individual's birth. For instance, everyone between 15 and 16 years old is considered 15. Calculate the individuals' age as follows and write it down in column 10.
If the month and year of birth mentioned in columns 8 and 9 is based on hijri solar calendar, do as follows:
If the person was born in Farvardin (April), Ordibehesht (May), Khordad (June), Tir (July), Mordad (August), Shahrivar (September), Mehr (October) or Aban (November), deduct his year of birth from 1385. For example, the age of someone who was born in Mordad (August) 1334, is 51 (1385 - 1334 = 51).
If the person was born in Azar (December), Dey (January), Bahman (February) and Esfand (March), deduct his year of birth from 1384. For example, if he was born in Dey (January) 1334, he is 50 (1384 - 1334 = 50) years old.
- For children younger than 1 year old (0 years old), write "--" in this column.
- If the person is age 100 or older, you don't need to calculate their age and just write "RR" in this column.
- For people whose date of birth is based on the hijri lunar calendar, deduct their year of birth from 1427 and write the result in column 10. For example, if someone was born in 1340 (in the hijri lunar calendar), he is 87 (1427 - 1340 = 87) years old.
- For those who have "--" in columns 8 and 9, write their age based on what they claim. If the respondent is unable to answer precisely, try to help them indicate their age based on other members of the household.
- For those whose month of birth is unidentified and their year of birth is on the hijri solar calendar, deduct the year of birth from 1385 to calculate their age.
Remember that filling out some other information later on in the questionnaire is directly related to individuals' age and any errors in calculating or writing down the age will also affect those columns.
- For your convenience, the ages of people who were born in 1285 and the following years in the hijri solar calendar have been calculated and are available in a table at the back of the maps folder. You can use this table to determine their ages.
