Some modern interpretations of the notion institute are discussed and a dominant admission limiting this notion interpretation variance is introduced. Reproduction of multiple inequalities is of the prevailing institutional character. That means that social institutes are taken synchronously in the context of the given conception both as reproducing and modifying inequalities, intensifying and smoothing them. The institutes are also interpreted as the active subjects, agents of inequalities reproduction, as well as of formation of individuals’ ways of inequalities perception, attitudes and estimates of own position and status in the society. A scheme of institutional reproduction of multiple inequalities described in the article contains such basic constituents: social institute, wealth/resources, inequality replication conditions, inequality modification conditions, interaction with other institutes, multiple stratification orders, and individuals.
