Summary The nationwide survey on Social Stratification and Social Mobility, also known as the SSM Survey, is one of the most traditional large-scale social surveys in Japan, and it has been carried out every ten years since the first survey in 1955 (by The Japan Sociological Society).

This 2005 survey is the sixth, and it was conducted by the SSM Survey Research Group of 2005.

The collapse of the lifetime employment system and the increasing number of part-timers (freeter) and part-timers/casual part-timers (arubaito) indicates that the labor market has become unstable. In this context, the current survey aims to reveal the relationship between fluidity and hierarchy/inequality of labor market in Japan. Also, with the background of increasing fluidity, to reveal the problems and issues of career (occupational careers) and how to think about one’s own career is of the main goal of this survey.

Also, this survey has been designed to make a reliable comparison between Japan, South Korea, Taiwan, and even with Europe and the U.S. depending on question items, and it has been developed as an international comparative survey.

Questionnaires are divided into interview questionnaires and placement questionnaires, and there are two types of placement questionnaire: A and B.
