As measured only by the combination of present Washington, Oregon, and British Columbia statistics, Cascadia would be home to slightly more than 15 million people (15,105,870), and would have an economy generating more than US$675 billion worth of goods and services annually. This number would increase if portions of Northern California, Idaho, and Southern Alaska were also included. By land area Cascadia would be the 20th largest country in the world, with a land area of 534,572 sq mi (1,384,588 km2), placing it behind Mongolia. Its population would be similar in size to that of Ecuador, Guatemala, or Zambia.
