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

(A good sequel to yesterday's post...) The Housing + Transportation Affordability Index is an innovative tool that measures the true affordability of housing based on its location. Users can view housing and transportation data as maps, charts, and statistics for nearly 900 metropolitan and micropolitan areas—covering 89 percent of the U.S. population. The interactive mapping tool was designed to enable individuals, planners, and policymakers to more fully grasp and act on the relationship between development patterns, transportation behavior, and household transportation costs.
