According to social identity theory, people seek to classify themselves and others on the basis of perceived similarities and differences.
As individuals create in- and out-groups from generational identities, interactions between members can be impacted and conflict can occur.
Under the concept of the intergenerational contract or agreement, written and/or unwritten rules of the redistribution of social status, which include wealth, power, and prestige, can exist between generations.
"[1] Intergenerational equity, in the sociological and psychological context, is the concept or idea of fairness or justice in relationships between children, youth, adults and seniors, particularly in terms of treatment and interactions.
[9] In the context of institutional investment management, intergenerational equity is the principle that an endowed institution's spending rate must not exceed its after-inflation rate of compound return, so that investment gains are spent equally on current and future constituents of the endowed assets.

Inter-generational ministry is one of a number of movements which have arisen in response over concerns that young adults very commonly cease participation in church, and often do not return.
This approach identifies parents as possessing religious agency and places young people as passive recipients of religion and the behavioral characteristics associated with a particular kind of faith.
Research also finds that children serve in a reciprocal approach, where the young person might influence the adult's religiosity and practices of worship and faith.
