Which concept refers to a group sharing similar experiences based on age?

The concept that refers to a group sharing similar experiences based on age is a cohort. Cohorts are typically defined by significant life events that occur within specific age ranges, such as those born in the same year or those who experience similar historical events at the same stage in life. This can include aspects like growing up during the same economic period, going through significant societal changes together, or sharing similar educational experiences.

Cohorts play a crucial role in sociological research as they help researchers understand how specific age-related experiences shape behaviors, attitudes, and social trends over time. By examining cohorts, sociologists can analyze how generational differences influence societal norms and values, thereby demonstrating the impact of shared experiences across a defined age group.

The other concepts, such as age stratification, life course analysis, and social construction, address various aspects of age and society but do not specifically refer to the grouping of individuals based on shared age-related experiences in the same way a cohort does. Age stratification refers to the hierarchical ranking of different age groups, life course analysis examines the various transitions individuals go through over their lifetime, and social construction discusses how societal norms and perceptions shape our understanding of reality, including concepts related to age.
