It's not straining. It demonstrates your faulty logic.and your straining exception of a college student abroad proves my point.
Anyway, it doesn't matter whether we counted them in a census or not as your just making an appeal to authority which doesn't make any sense. The census bureau was created to sort out what constitutes personhood and even if it did it's conclusion would not mean anything unless they were based on unquestionable fact.
Btw, do you see how you contradicted yourself?
