The World's Leading Science Cities

Science Cities - Producers vs. Consumers

Cities that produce knowledge are red; those that consume it are blue

Within the U.S., there has been a shift in scientific production from the "major urban areas" of the East and West Coasts to a broader geographic distribution which includes centers in the Midwest and South

Despite America's overall decline, major cities and urban centers on the east and west coast remain the leading centers of physics over this period. The U.S. had 17 of the top 20 cities in 1990 and 14 in 2009

NOTE:

While Chinese cities have risen as consumers of scientific knowledge (alongside their economic growth), it remains to be seen if they can become leading  producers of it.
