“These 23 megapolitan areas – further combined into 10 clusters – are projected to house about two-thirds of the U.S. population in 2040. Strong foreshadowing of the megapolitans can be seen today, the authors say. Dallas-Fort Worth is just one example, which by itself extends to include a total of 29 counties. The Dallas-Fort Worth megapolitan is further connected to two others in the area, one driven by Houston, the other by Austin and San Antonio. Together these three megapolitans form a 67-county cluster Nelson and Lang refer to as the Texas Triangle, which they predict that by 2040 will house more than 28 million people.”
