ABSTRACT
Social mobility and intergroup associations are two social processes that link different positions, groups, and classes in a social structure. These links are attenuated by social barriers that inhibit the chances for mobility and for intimate relations between members of different groups and classes. Such conditions weaken the integration of a community or society. Social mobility typically results in structural change, that is, in changes in population distributions, whatever the ultimate exogenous conditions that created the demands for the redistribution of people. This chapter examines the relationships of mobility with social associations and with changes in structural differentiation in any one dimension. Changes in inequality are usually precipitated by social mobility, but not always. Differential fertility, as it alters the size distribution, also changes inequality. Intermarriage in terms of occupational origins of the two spouses is based on a matrix cross tabulating father's and father-in-law's occupation.
