ajankohortti
Ajankohortti is a Finnish term that translates to "time cohort" or "age cohort." It refers to a group of individuals who share a common temporal experience, most commonly being born in the same year or period. This concept is widely used in sociology, demography, and epidemiology to study how historical events, social trends, or environmental factors uniquely affect individuals based on when they lived through them.
For example, a study might examine the "baby boomer" cohort, individuals born roughly between 1946 and 1964,
Researchers analyze ajankohortti to identify long-term patterns in health, education, employment, and other life course variables.
