Finally, the Expanding Circle encompasses countries where English plays no historical or governmental role, but where it is nevertheless widely used as a medium of international communication. This includes much of the rest of the world's population not categorized above, including territories such as China, Nepal, Russia, Japan, non-Anglophone Europe (especially the Netherlands and Nordic countries), South Korea, and Egypt. The total in this expanding circle is the most difficult to estimate, especially because English may be employed for specific, limited purposes, usually in a business context. The estimates of these users range from 100 million to one billion.
