cohortpeople

Cohortpeople is a term used in social science and statistics to describe individuals who belong to a defined cohort, typically sharing a common temporal boundary such as a birth year, year of program entry, or date of cohort formation. The concept emphasizes group-level analysis of people with shared starting conditions, distinguishing cohortpeople from analyses that focus on individuals in isolation.

In research, cohortpeople are identified within longitudinal data and tracked over time to observe how cohort-specific experiences influence outcomes such as health, education, employment, and social behavior. By comparing cohorts, researchers can separate effects due to aging from effects tied to the historical period or to the cohort's unique life events.

Applications include public health, where birth cohorts reveal patterns of disease incidence and mortality; economics and labor market studies, where income and employment trajectories are examined by cohort; and education and social policy, where program effects are evaluated by cohort entry year.

Methodological considerations include defining the cohort consistently, handling censored data in longitudinal tracking, and addressing biases arising from selective survival and missing information. The term "cohortpeople" is informal and not universally standardized; researchers typically refer to "a birth cohort" or "the cohort of people who entered a program in a given year."
