    Next, survey areas in each stratum were selected at random. The number of survey areas was determined for each stratum based on the assumption that approximately 6 people would be selected to be surveyed in each area.

    Details of the allocation of the sample across regions and city class are as follows

  5. (5) Choice of the reserve subjects
    In order to obtain a sample of 1,000 individuals, originally selected subjects that did not take part in the survey were replaced by individuals who were previously selected as reserve subjects.
    The reserve subjects were selected to have the same sex (male or female), and the same age grouping (in their 20s, in their 30s, in their 40s, in their 50s, in their 60s, in their 70s or over) as the original individual.

For this group, the survey is totally selfadministered.
