I would expect the reverse in many cases - initial install without
Xcode, followed by upgrade to Xcode.  Equally problematic, though.

As for numbers, it depends on how you define "developer" - installs
without Xcode might well be more numerous, and people with such
installs might be more numerous on the email lists etc., but in
terms of the platform per se, they're kind of dead weight.
