Along with the high growth of the Japanese economy, peoples' class identification increased from relativelys “lower (class)” to “middle (class)”. About 75% of Japanese people identify themselves as “middle (class)” in 1975. However, the distribution of it has not dramatically changed since 1975.
In this paper, I apply the same liner causal model to 1975, 1985, 1995 SSM male sample, in order to examine the latent change of the status determinants in these 20 years. Using the same model, I also analyzed the female sample of 1985 and 1995 SSM. This confirms the similar tendency appeared in the male sample. All of these results suggest the following conclusions.
1) As Naoi (1979) and others have insisted, socio-economic status had little effect on class identification in 1970s'.
2) In 1980s', income as well as life satisfaction were the most significant determinants of class identification, though occupation and education did not have significant effects. This can be called the period of economic and subjective determinants.
3) In 1990s', occupation, education, income and life satisfaction have significant effects on class identification. Consequently, R square, which was only 9.3% in 1975, rose to 18.4% in 1995. This can be called the arrival at the period of the multiple determinants of class identification.
