Dai 1 Kai Zenkoku Kazoku Tyousa (NFRJ98).
- Survey date, method, and implementation
In January 1999,
a canvasser from Tyuuou Tyousa-sya visited each respondent and handed a questionnaire.
Later the same canvasser picked up it, which the respondent had filled in.
- Sampling scheme
The population was Japanese women and men born 1921-01-01 through 1970-12-31.
Based on a stratified two-stage probability-proportional-to-size sampling,
10500 residents were extracted from 535 Census districts.
Zyuumin Kihon Daityou [the principal resident registor] for 502 districts and
Senkyonin Meibo [the voter registration list] for 33 districts were used.
The sample was split into two subsamples by age:
the young sample born after 1941-01-01
and the aged born before.
For these two subsamples, we used two different questionnaires:
- Ippan Tyousahyou [Basic Questionnaire] of 19 pages
was for respondents born after 1941-01-01
- Koureisya Tyousahyou [Questionnaire for Aged] of 25 pages
was for respondents born before 1940-12-31.
The same questions as the Basic Questionnaire constitute
pages 1-19 of the Questionnaire for Aged;
only the latter has additional pages 20-25.
Questions in the Basic Questionnaire:
- o Face sheet
Experienced of leaving home.
Occupation (the first and current one).
- o Conjugal relations
- Marital status.
When they got married.
The same/different surnames.
Spouse's character (age, education, occupation, income, and so on).
Degree of companion.
Division of household labor.
Experiences of divorce or bereavement.
Experiences of labor force exit on marriage.
- o Quality of life, etc.
- Normative consciousness on the family.
- o Children
- The number, sex, age, and marriage status of children.
Relations with the children.
- o Parents
- When the parents were born (and died).
Ralations with the parents.
- o Siblings
- The number of siblings.
Relations with siblings.
- o Parents in law
- When the parents-in-law were born (and died).
Ralations with the parents-in-law.
- o Other relatives
- Supports and troubles with relatives within the past one year.
Support resouces from non-relatives.
The number of relatives and the subjective domain of the "family".
Additional quetions in the Questionnaire for Aged:
- o Experience of nursing
- Experience of nursing parents, parents-in-law, spouses, and so on.
- Response rate
From the designed sample of 10500 persons (5163 men and 5337 women),
we obtained 6985 valid responses (3323 men and 3662 women).
The valid response rate thus becomes 66.5% (64.4% for men and 68.6% for women).
NFRJ98 data were first subjected to a joint research among NFR members.
The dataset was settled a logical checking,
and has been distributed to the members since September 1999.
I gratefully acknowledge the voluntary data-checking task.
After the publication of the final reports in 2001,
NFRJ98 data was opened to public via
SSJ Data Archive (No. 0191) by Institute of Social Science, University of Tokyo.

Tokyo preliminary surveys in 1997
Before the first national research was designed,
two preliminary surveys were conducted in the Tokyo metropolitan area.
Each of those was granted by Monbusho Grant-in-Aid for Scientific Research.
Reports were submitted to Monbusho:
- Syousika to oyako kankei ni kansuru tyousa
[Parest-child relationships in a childless society]
- Huuhu/oyako kankei no sokutei to houhou: NFR yobi tyousa deta wo motiite

National Survey of Families and Households (NSFH)
NSFH is the largest family research in USA.
The NFR members have compared the NSFH data to Japanese ones,
especially to the above two preliminary surveys in Tokyo.
The NSFH data are available via FTP.
