You shouldn't be running it but a hell of a lot of people and businesses still are. And MS is to blame IMO. The continued extending support, they screwed up with Vista and after making things right with Windows 7 screwed up again (although no where nearly as badly as with Vista) with Windows 8.
I also know of people running XP because it's incredibly stable now and they don't see anything in newer versions of Windows they really want or need.
