USA! USA! USA!

The United States is 49th in the world in literacy (the New York Times, Dec. 12, 2004).
The United States ranked 28th out of 40 countries in mathematical literacy (NYT, Dec. 12, 2004).
Twenty percent of Americans think the sun orbits the earth. Seventeen percent believe the earth revolves around the sun once a day (The Week, Jan. 7, 2005).

From that site:

"The actual number of foreign first year graduate students declined only slightly in the past few years, from 1485 in the fall of 2000 to 1294 in the fall of 2004, while the number of US students rose from 1228 in the fall of 2000 to 1746 in the fall of 2004. "

There are more undergraduate students than that.  Way, way more.
