The map above shows the Regional Plan Association’s list of 11 Mega-Regions of the United States as part of their America 2050 project.
In terms of the estimated population in 2025 they would rank in the following order: (population in 2010)
- Great Lakes: 60.7 million (55.5 million) – includes Chicago, Toronto, and Detroit
- Northeast: 58.4 million (52.3 million) – includes New York, Boston, Philadelphia and Washington
- Southern California: 29 million (24.4 million) – includes Los Angeles, San Diego and Las Vegas
- Texas Triangle: 24.8 million (19.7 million) – includes Houston, Dallas, San Antonio and Austin
- Piedmont Atlantic: 21.7 million (17.6 million) – includes Atlanta
- Florida: 21.5 million (17.3 million) – includes Miami, Orlando, and Tampa Bay
- Northern California: 16.4 million (14 million) – includes San Francisco, San Jose and Oakland
- Gulf Coast: 16.3 million (13.4 million) – includes Houston and New Orleans
- Cascadia: 13.5 million (12.4 million) – includes Vancouver. Seattle and Portland
- Arizona Sun Corridor: 7.8 million (5.6 million) – includes Phoenix
- Front Range: 6.9 million (5.5 million) – includes Denver
Notes:
- The populations given for megalopoleis that extend into Canada and Mexico (Cascadia, Great Lakes, and Southern California) include their non-U.S. residents.
- Houston appears twice (as part of Gulf Coast and Texas Triangle).
You can read the Wikipedia article to learn more about where the whole idea for these comes from.

Disgusting and threatening Elites idea of Global Multinational Wealth . This Pathetic idea of cramming millions into ” Regions ” through a Professor Quack of Berkeley brain child , is nothing more than a United Nations Democratic World Order to control all Humans ! and most are stupid enough not to see through it . Live Rural my Friends , or your Forefathers small towns again . Don’t get caught up in this disaster !

Toronto Ontario and Vancouver British Columbia should not be included, or should they want to be. Please confine your Mega Regions of the US…..to the US.

A major flaw I see is Florida. This doesn’t take into account the ongoing sea rise that will probably make most of southern Florida either undesirable or even a nonviable place to live.
