I have a set of customer data with an actual date of birth and from an external data set I have appended a modelled age banding/group. I have converted the actual dates of birth into the same range bandings/groups as those present in the modelled age bandings/groups. I would like to understand how accurate the modelled age banding is versus the actual age banding.
The age bandings are as follows:
18-25
26-35
36-45
46-55
56-65
66+
I have attached a sample of dummy data for reference
