[ELI5] Why do some neighborhoods have USPS delivery to the door and others only to the driveway?

Question

I have seen some high-end neighborhoods with delivery to the mailbox at the entrance and middle-class neighborhoods with delivery to the door. So I suspect it isn’t some local tax thing either like garbage pickup.

Edit: Meant paper mail delivery to clarify!

Answer 1

Talking about paper mail only?

Some areas have postal workers that walk, could also be due to theft.
