Description

Definition

SEIUS is a constructed variable that assigns a Duncan Socioeconomic Index (SEI) score to each occupation. The SEI, based on the 1950 occupational classification system, is a measure of occupational status based upon the income level and educational attainment associated with each occupation in 1950. The score was derived by using median income and education levels for men in 1950 to predict prestige assessments from a 1947 survey (of a select group of occupations). The resulting statistical model was used to generate scores for the entire range of 1950 occupations. See O. D. Duncan, "A Socioeconomic Index for All Occupations," in A. Reiss et al., Occupations and Social Status (Free Press, 1961).
