False.

The most famous megalopolis is the Northeast Megalopolis, which stretches from the northern suburbs of Boston, to the southern suburbs of Washington, DC. The area is a line of almost unbroken urban and suburban zones, is home to 49.6 million people (17% of the population of 2% of the US' land area), and 20% of US gross domestic product.

Other Megalopoli in the US include Cascadia, stretching from Portland to Boise; the bulk of Florida (excluding the panhandle); the Gulf Coast, the industrial shores of the Great Lakes; Northern California (Fresno, Reno, Sacramento, San Jose); the Piedmont Atlantic, comprising the non-coastal cities of the Upper South; Southern California (Bakersfield, Anaheim, Los Angeles, Los Vegas, San Bernardino, and San Diego); and the Texas Triangle of Austin, Dallas-Fort Worth, Houston, and San Antonio.
