Principal Investigator(s): Choe, Minja Kim, East-West Center; Tsuya, Noriko, Keio University (Japan); Rindfuss, Ronald, East-West Center, and University of North Carolina-Chapel Hill; Bumpass, Larry L., University of Wisconsin-Madison


The Japan 2009 National Survey on Family and Economic Conditions (NSFEC) queries a targeted age cohort of Japanese adults on various facets of familial and economic life. The collection, assembled by the Keio University, features two components: (1) a new cross-sectional survey of 3,112 respondents from a nationally representative sample of Japanese men and women aged 20-49 years, and (2) a 2009 follow-up survey of 2,356 out of 4,482 original respondents from the Japan 2000 NSFEC. Respondents were asked questions regarding child rearing, household division of labor, gender roles, and educational background and employment of parents. Respondents were also probed for opinions on marriage, divorce, cohabitation, sexual activity outside of marriage, and children born out of wedlock. Demographic information includes age, sex, education, number of siblings, marital status, household income, home ownership, and number, age, and sex of children.
