What are the most common age groupings on sign-up forms?
The person I’m making a website for wants to have users enter what age group they currently belong to when they register, rather than have to supply their exact date of birth.
So I was wondering…
What are the most common age groupings? Else, are there particular sets/spacings between ages that have a more balanced or representative nature than others?
It’ll only be used for user demographics if that makes a difference
