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 1965 survey is the second of its series.

In 1980-81, the SSM Trend Analysis Research Group recoded specific survey items from the original questionnaires used in the Social Stratification and Social Mobility Survey for 1955 and 1965. Recoded items included occupation, level of educational attainment, income, and other status variables, as well as region and occupational aspirations. In addition, respondents aged 70 years and older were originally included. To facilitate comparative analysis, resampling was carried out and those aged 70 years and older were excluded.

The data available from the SSJ Data Archive is the resampled and recoded data.
