"Asians" doesnt mean much, if it has to mean someone from the continent of Asia, given 60% of world population is from Asia.
Sweden includes all people from the Asian continent as Asians in their stats.
Americans has this weird definition of "Americans".
They define "Asians" by race and looks. Typical.
Well, that's not necessarily an American thing. For a long time, the race that's currently described as "asian" was called "oriental" and specifically referred to that race. For some reason, the more specific term "oriental" fell out of favor (and is even considered offensive now, although I'm not quite sure why) and was replaced with the more generic, and somewhat confusing, "asian".
