Definitions for "Cohort analysis"
A social scientific technique that studies a population that shares common characteristics over time. Cohort analysis usually begins at birth and traces the development of cohort members until they reach a certain age.
A study of a group of people who stay in that group over a long time. For example, all people born in 1960 are a cohort; or all students who will graduate from high school in 1999. The study follows this group over time, rather than looking at them once.
Same as Virtual Population Analysis.
