Summary “The Third National Family Research of Japan” (NFRJ08) is the third survey of the continuous national research project, the National Family Research of Japan (NFRJ) project, which began in 1998. NFRJ08 was conducted by the National Family Research Committee of the Japan Society of Family Sociology between January and February, 2009.

In order to analyze the trends of contemporary Japanese families, the NFRJ project has three objectives: (1) to grasp current conditions through representative datasets, (2) to construct datasets which make it possible to analyze changes and trends through continuous surveys, (3) to expand the possibilities for a joint analysis framework through opening and sharing data and to promote statistical data sharing about contemporary families. The first survey in this project, “The First National Family Research of Japan” (NFRJ98), was conducted in 1999, followed by “The Second National Family Research of Japan” (NFRJ03) in 2004. The results of these surveys are published as survey reports and as academic library resources. Each dataset was made public through SSJDA (NFRJ98: 0191, NFRJ03:0517).

NFRJ08 follows the basic design of NFRJ98 and NFRJ03 as a continuous survey to grasp trends in Japanese families. NFRJ08 has improved upon previous surveys in two ways. First, the age range of the sample has been lowered. The age range in NFRJ98 and NFRJ03 was from 28 to 77 years old; in NFRJ08 the upper age limit was lowered to 72 years old. Second, the age brackets of the questionnaires have been revised. To better facilitate survey distribution and cooperation, the two types of questionnaires (Youth, Old and Middle age) used in previous surveys have been divided into three (Youth: born between 1961 to 1980, Middle-aged: born between 1946 to 1960, Old age: born between 1936 to 1945). Furthermore, a monitoring method-based pretest has been introduced to improve upon previous questionnaires.
Universe Men and women who were born between 1936 and 1980. (28-72 years of age as of December 31, 2008)
*Includes only men and women registered with the resident’s registry.

More precisely, the Universe consists of individuals residing in Japan (but except those who live in small islands at which it is difficult to do the fieldwork) and who meet both of the following conditions;
1. Born between 1936 and 1980 (28 - 72 years of age as of December 31, 2008)
2. Registered with the Basic Residents Register of municipalities.
Non-Japanese nationals living in Japan were excluded from the universe, as they did not meet the 2nd condition (only Japanese national holders were listed in the Basic Residents Register at the time of survey).
