Explanation:
When it comes to marketing, the term "cohort" refers to specific experiences, events or other factors shared by a group of consumers. These cohorts are used to identify and target segments of the market that, although they may fit into other models, are more effectively grouped and treated as one.
Cohorts are the things that separate specific groups of people even within their demographic groupings. For example, men between the ages of 55 and 70 are a demographic grouping.
