Cohort
A group of records that share the same starting period or trait.
Definition
Cohort is A group of records that share the same starting period or trait. It comes up most often when the data needs to be broken into comparable groups instead of being treated as one average pile.
The term keeps showing up because segmented analysis is where patterns emerge that a top-line report will always hide. It helps teams see which residents, assets, or time periods are actually driving the result.
Use cases
Use Cohort to break a blended result into groups that can actually be compared.
Review Cohort when the team needs to show which cohort or segment is driving the change.
Track Cohort so operations can avoid making portfolio decisions off one misleading average.
