Summary Along with changes in the labor market structure, the drastic decline in the birthrate, the growing proportion of elderly people, and the progress of globalization, the way of employment, marriage, family, education, social attitudes, and lifestyle in Japanese society are about to undergo a substantial change. When considering the future direction of Japanese society, it is extremely important to clarify the cause of changes that are currently occurring, or where these changes are occurring.

The panel research project of the Institute of Social Science of The University of Tokyo uses a panel (follow-up) survey method to empirically elucidate these issues. For this reason, the Institute of Social Science at The University of Tokyo is implementing three panel surveys, as a nationwide survey on changes in working style and lifestyle (called the Japanese Life Course Panel Surveys, or JLPS). JLPS consists of a youth panel (JLPS-Y), a middle-aged panel (JLPS-M), and a panel of high school graduates (JLPS-H).

JLPS-Y and JLPS-M, which started in January 2007, include comprehensive questionnaire items on topics such as occupation, family, education, social attitudes (including political attitude), health, etc., and is one of the few large panel surveys in Japan. Items related to occupation are also very detailed, and items in compliance with the national survey on social stratification and social mobility (SSM Survey) are being asked.

In this way, JLPS is not only focused on a design that allows for international comparative analysis, especially with reference to the experience of extensive panel surveys in the UK and the US, but we also refer to survey items of existing Japanese surveys (including cross-sectional items).

JLPS-Y covers the so-called “young generation” from 20 to 34 years old as of the end of December 2006, and JLPS-M covers the “middle-aged generation” from 35 to 40 years old. The question items for both groups are the same.

Among the above three surveys, the survey recorded here relates to “Japanese Life Course Panel Surveys of the Youth” (JLPS-Y) Wave 1 and Wave 2 conducted in 2007 and 2008 respectively. The survey has been scheduled to continue every year after that. The “Middle-aged Panel Survey” conducted in the same period in 2008 is included in SSJDA survey number PM020.

For the “Youth Panel Survey (Wave 1)” conducted in 2007, please refer to PY010.
