cohort
English meaning: Cohort
English Definition
(English)A cohort (originally a Roman military unit) in social science refers to a group sharing a common temporal experience — typically a birth year range (Generation Z: 1997-2012; Millennials: 1981-1996). Cohort effects distinguish the impact of generation from age effects (changes that occur with ageing) and period effects (events affecting everyone simultaneously). Cohort analysis is essential in epidemiology, education, and policy evaluation.
English Definition
A group of people who share a defining statistical or demographic characteristic — especially birth year (birth cohort), or who experience the same event at the same time. Cohort analysis tracks how different generations behave and are affected by policies differently.
Example
“The COVID cohort — children who experienced lockdowns during critical developmental years — may show lasting educational and psychological differences from preceding cohorts.”
In English: “Pandemic-era children form a distinct cohort whose developmental experiences differ markedly from prior generations.”
