Age integration – a term used in social gerontology in at least two senses. In a narrow perspective – adopted mainly in English-language literature – age integration refers to such a structure of social roles in various institutions that allows for differences, but they do not depend strictly on the age structure, i.e. whether someone is a middle-aged adult or in an older age (Phillips et al., 2010). This is particularly about educational, economic, political, religious and leisure institutions in which people from different age groups and generations play different roles and occupy different positions. Age integration is based on the assumption that access to the institution, the possibility of exiting it and access to products (called outputs); services implemented in reality and benefits and outcomes paid out; the effects of implemented services and services, eg reduction of poverty, improvement of health, activities of these institutions is equal for all regardless of age.
