Orphaned, at what age?

At what age would one stop being labeled an orphan? I mean, if one's parents died when one was over 20, for example, could one still be called an orphan?

I guess it would depend on the person. At least for me, when I was twenty, I still felt as much like a child as I did did when I was 12. Some people feel all grown up and independent by the time they're 16.
