Cohort analysis is a research method used in social sciences, marketing, and other fields to study groups of individuals over time. A cohort is a group of individuals who share a common characteristic or experience within a defined period. Cohort analysis allows researchers to track and analyze the behaviors, attitudes, and outcomes of specific cohorts to better understand how various factors impact them. By studying cohorts over time, researchers can identify trends, patterns, and correlations within specific groups. This type of analysis can help researchers make comparisons between cohorts and draw conclusions about the factors that influence their behaviors and outcomes. Overall, cohort analysis is a powerful tool for understanding how different groups of individuals experience and respond to various phenomena, and it can provide valuable insights for informing policies, strategies, and interventions.
