Interviewer instructions
Enter age as a 2-digit number; if less than 10 years, prefix a “0” to make it a 2-digit code. For infants less than 1 year as of the day of your visit, enter “00'. For persons aged 98 or over, enter “98”.
If the respondent cannot give exact information about the age of any one member of the household, politely ask him to give his best estimate. In the remote case that he cannot or he refuses to give even an estimate, enter “99” in column 7 for that member to indicate that age is unknown.
