535 locales in Japan (110 locales from 13 major cities; 200 locales from cities with populations greater than 100,000; 102 locales from cities with populations less than 100,000; 123 locales from towns and villages)
Sampling method
Stratified two-stage random sampling. 152 strata were set by dividing muncipalities in 47 prefectures into 4 categories based on thier population; from these strata 535 points were sampled with proportional probability. Other strata were created for gender and age, which set quotas for sampled number of people. The required number of people was selected using the systematic sampling method on the Zyuumin Kihon Daityou [residents register] (for 502 points) or Senkyonin Meibo [voter registration record] (for 33 points).
Survey method
Leave and pick-up
Questionnaires
We used two types of questionnaires: the general questionnaire (for those born between 1941 and 1970) and special questionnaire (for senior respondents born between 1921 and 1940). The latter is the same as the former with some additional questions (regarding nursing care) at the end.
