Interviewer instructions
15. Date of birth, Columns 8 and 9
Ask the respondent to inform you of the year and month of birth of the members based on official documents. Then write them down as 2-digit numbers in columns 8 (month) and 9 (year). For people who don't have proper documents, put down the date they claim. If the respondent does not know, for people younger than 100 years old, write "--" in columns 8 and 9 and for people older than 100 years old, write "RR" in column 8 and "--" in column 9. In cases when the actual date of birth is different than the one on birth certificate, consider the one on the birth certificate.
