Register new User - Department

Probably a simple question - but I've not found the answer yet using some basic "find"ing through the code.
I'd like to change the static text for the field names on the Register new user screen. I don't mind if the underlying field remain the same name, nor do I need any change to the data. I'd just like to change the static text "Department" so that I request a different piece of user data and store it in Department.
Where can I change that? Any help appreciated.
