خلاصه	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.	A social mobility table is a cross-classification of individuals by their social origin (typically a parent's class or occupation) and their own destination class, forming the empirical foundation of intergenerational mobility research. Analyzing it separates how much people move between classes, distinguishes movement forced by changing class sizes from genuine exchange, and isolates the underlying origin–destination association that measures the openness of a society.
