תקציר	The status attainment model, introduced by Peter Blau and Otis Dudley Duncan in The American Occupational Structure (1967), is a recursive path model that explains an individual's occupational status from their social origins and intervening achievements. In its basic form, father's education and father's occupation influence the respondent's education and first job, which in turn shape current occupational status. By decomposing the link between origins and destinations into direct and education-mediated indirect paths, it established that education is the principal channel through which advantage is transmitted across generations.	Log-linear mobility models analyze an origin-by-destination mobility table by modeling the logarithm of its expected cell counts as a sum of terms: separate effects for the origin and destination marginals plus interaction terms that capture the origin–destination association. By specifying that association parametrically — through diagonal, level, or scaled terms — these models test precise hypotheses about the structure of social fluidity independent of the changing sizes of classes.
