| USA has 9 clear cities over 1 million. That's an undisputable fact. NYC, LA, CHI, PHX, PHIL, DAL, HOU, SD and SA. As far as Australia, I've checked several sources and they all list those same 5. Different countries undoubtably use different standards when defining cities proper vs. metro areas, so the best I can do is pick a source and go with it. If you disagree, make another quiz! :) |
