Dirty Rear Bumper

Every time I wash my car, I notice that one of the most dirty places on the car is on the upper portion of the rear bumper (along the entire length of the upper rear bumper) where the trunk mates with the rear bumper. Why is this area sooo dirty? Is it the airborne exhaust emissions that get blown by the wind and then hit the upper rear bumper?
