We used two types of questionnaires: questionnaire for young respondents (for those born between 1956 and 1975) and questionnaire for middle-aged or senior respondents (for those born between 1926 and 1955). Most questions are common across both questionnaires. However, the former has special questions about marriage, childbirth, and childcare. The latter has special questions about relations between older parents and thier children.
