The transmission of social inequality: Examination of the linkages between family socioeconomic status in childhood and educational achievement in young adulthood

The present study examines the linkages between family socioeconomic status (SES) in childhood and educational achievement in young adulthood using data from a 25-year longitudinal study of a birth cohort of over 1000 New Zealand children. Structural equation modeling of the association between latent SES at birth and educational achievement by age 25 years showed evidence of a strong association between latent SES and later educational achievement. Much of this association was mediated via two pathways relating to child cognitive ability and family educational aspirations; family economic resources and school factors did not mediate the association. However, even when the major theoretical pathways were taken into account, a substantial component of the latent SES/educational achievement correlation remained unexplained.
