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.

survey data



2013-06-06 ICPSR data undergo a confidentiality review and are altered when necessary to limit the risk of disclosure. ICPSR also routinely creates ready-to-go data files along with setups in the major statistical software formats as well as standard codebooks to accompany the data. In addition to these procedures, ICPSR performed the following processing steps for this data collection:

  • Created online analysis version with question text.
  • Checked for undocumented or out-of-range codes.

Dataset 1 contains a weight variable (newweight) that should be used in analysis. Weights were computed based on age, sex, the size of place of residence, and region. Dataset 2 does not contain a weight variable.


  • Data in this collection are available only to users at ICPSR member institutions.
