  • Abstract

    The National Family Research of Japan (NFRJ) is a series of nationwide surveys of families selected by random sampling in Japan. It is organized by the National Family Research committee of the Japan Society of Family Sociology. The aims of the NFRJ are to provide data for further improvements of family research and to contribute to the accumulation of new knowledge in Japan. The NFRJ study group aims to describe and explain the changing individual attitudes and variations of experiences in regard to life events related to changes in families, and longitudinal variations of family groups recognized by individuals. National Family Research of Japan 2008 (NFRJ 2008) is the third survey in the NFRJ series. Most of the questions in NFRJ 2008 were taken from NFRJ 1998 and NFRJ 2003. However, the wording of some questions and the available responses were altered. NFRJ 2008 had three forms of questionnaire for separate age groups: younger (28-47 years), middle-aged (48-62 years), and older (63-72 years). Opinions were collected on marital quality, work and family, parenting, parent-child relationships, siblings relationships, and division of household labor. Additional topics include respondent relationships with siblings, in-laws, and parents, employment type, work environment, and work-life balance. Demographic information includes respondent age, gender, education level, income, and marriage and employment status.

Stratified two-stage random sampling was used. Primary sampling units (Census tracts) were stratified into 108 by prefecture (47) and population size(3). The number of census tracts to be selected in each stratum was determined on the basis of the size of the target population (people aged 28 to 72). In total, 9400 individuals in 480 tracts were selected. The above tasks were carried out from November to December in 2008.
