| Summary |
The structural changes in the labor market, the rapid aging of society with a declining birthrate, and the advance of globalization have brought about significant changes in the nature of employment, marriage, family, education, attitudes, and lifestyles in Japanese society. In considering the direction in which Japanese society will move in the future, it is essential to clarify the causes of the changes that are currently occurring and which aspects of Japanese society have changed and which have not. The Institute of Social Science, the University of Tokyo's Panel Survey Project aims to empirically elucidate these issues by using panel (follow-up) survey methods. For this purpose, Institute of Social Science, the University of Tokyo is conducting four panel surveys: of young generation (JLPS-Y), middle-aged generation (JLPS-M), high school graduates (JLPS-H), and junior high school students (JLPS-J) as “the Japanese Life Course Panel Surveys“ (JLPS). The JLPS-Y and JLPS-M, launched in January 2007, are among the few large-scale panel surveys in Japan that include comprehensive questions on occupation, family, education, attitudes (including political attitudes), health, and so on. In addition, the occupation items are very detailed, asking questions that conform to the National Survey of Social Stratification and Social Mobility (SSM survey). Thus, the JLPS is not only designed to allow for international comparative analysis, drawing on the rich experience of panel surveys, especially in the U.K. and the U.S., but also draws on survey items from existing Japanese surveys (including cross-sectional ones). The JLPS-Y targets so-called "young generation" aged 20 to 34 as of the end of December 2006, while the JLPS-M targets "middle-aged generation" aged 35 to 40. The questions in both surveys are identical. The surveys included here are the J Japanese Life Course Panel Surveys of the Youth (JLPS-Y) Wave 1 through Wave 10, which were conducted from 2007 to 2016. The survey will continue to be conducted annually after that. The JLPS-M conducted in the same period in 2016 is included in the SSJDA survey number PM100. For the JLPS-Y (waves 1 to 9) conducted from 2007 to 2015, please refer to the following. PY010 PY020 PY030 PY040 PY050 PY060 PY070 PY080 PY090 In 2011, we added subjects of the same age as those in the ongoing survey (24 to 38 years old in 2011) to address the problem of respondents dropping out due to long-term follow-up. The data of the continuous survey from 2007 is PY100, and that of the additional survey from 2011 is PY100_add2.
