The biggest areas will remain NY and LA, and I predict Riverside will be included in LA metro. I think Milwaukee may be added to Chicago. US cities continue to spread outward, so I am guessing other metros like DFW, Houston and Atl will gain new counties. It will be interesting to see if Austin and San Antonio merge, although I do not know if how much growth is between them.

The US is obviously an economic powerhouse but I think NYC will be the only US city in the top 50 worldwide by 2046 (well maybe LA with Riverside as near the bottom of the top 50). I wonder if even the US will have any skyscrapers in the top 50 by 2046 as well, and the Empire State Building may not be even in the top 100.
