- While the term “cohort” is typically used to describe age (age cohort) it can mean any demographic characteristic such as people with children, people who are married, or people who have a degree in sociology.
- Cohorts often exhibit a cohort effect.
- In cohort studies, an inception cohort describes a group of people followed from an early and consistent point. For example, the onset of a disease or the first day of university. Another example, is the long running documentary project, The UP Series. The project has followed 14 British children since 1964, starting when they were seven-years-old, with another installment every seven years. The last installment was in 2019, when the participants were 63-years-old.
- “The Baby Boomers are a defining feature of American society and a touchstone for research on aging and the life course. Boomers have embodied many trends, from the sexual revolution to rising women’s workforce participation to changes in intergenerational relationships. While unique for its sheer size, the cohort is also unique for its trajectory. The Baby Boomers came of age during a period of great technological and social innovation. With important implications for family life, their aging is a testing ground for theories of cohort and generation, and it underscores the importance of research on the older population and later life. To review facts well known to sociologists, the Baby Boomers were born between 1946 and 1964. Their defining feature is the cohort’s size. Much to the surprise of demographers accustomed to the low fertility of the 1930s, the U.S. birth rate remained high for nearly 20 years before it fell to the low levels we know today” (Treas and Marcum 2011:132).
