Japanese densities, apparently:
Seattle is the center of one of 10 “megapolitan clusters” that will drive the U.S. economy over the next 30 years, according to a new book.
This growth will drive the Puget Sound area’s density from less than that of Germany to about what Japan has now, according to “Megapolitan America: A New Vision for Understanding America’s Metropolitan Geography…”
… it would boost Cascadia’s population density from 482 people per square mile (roughly that of Switzerland) to 679 (more than in the United Kingdom). Puget Sound density would surge from 576 people per square mile (less than Germany) to 809 (similar to Japan).
