Sažetak	The Duncan Socioeconomic Index (SEI), created by Otis Dudley Duncan in 1961, assigns each occupation a socioeconomic status score derived from the education and income of its incumbents. Duncan calibrated the score by regressing the prestige ratings of a limited set of occupations on the percentage of incumbents with high education and high income, then used that equation to predict a status score for every occupation in the census. The SEI thus extends a small number of prestige ratings to the entire occupational structure on a 0–100 scale.	The intergenerational elasticity of income (IGE) is the workhorse measure of economic mobility: the regression coefficient from regressing a child's adult log income on the parent's log income. It expresses the percentage by which a child's expected income rises for each one-percent increase in parental income, so a higher IGE means income advantages and disadvantages are more strongly transmitted across generations and society is less mobile.
