Age segregation deprives individuals from certain age groups from interacting with others outside their age cohort. It implies the separation, exclusion, isolation, or special treatment of individuals and groups by virtue of their age, by enforced or voluntary residence in a restricted area (see “Age-Cared Homes” and “Age-Friendly Cities and Communities”), barriers to social intercourse, exclusion from the labor market, or by other discriminatory means. When age segregation is due to cultural, political, or economic pressure, it promotes ageism, denying all generations the benefits of diverse social interaction.
