Warning: these figures indicate the number of cases found in the data file. They cannot be interpreted as summary statistics of the population of interest.
Enter each person's age in completed years, that is, his/her age at his/her last birthday. Completed age is also defined as 'the number of completed years since birth'. With this definition, since a 6-month-old baby has not completed a full year, his/her age will be entered as '00'. Note that you will be obtaining more accurate estimates of children's ages later.
This column should never be left blank.
Even after you have probed and asked all the necessary information from the respondent and you still have difficulty obtaining the ages of elderly members of the household, you may enter the code '98', meaning 'Doesn't know/over age 50'. For household members younger than 50, completed ages must be entered. However, you should still indicate, with a note, what age range the person in question might be, so that your editor or supervisor can have an idea of the eligibility of the person to administer the individual questionnaires.
If the age of the member of the household is 95 or higher enter the code '95' for all such cases.
