ANN ARBOR, Mich. (AP) — Want to see how quickly the look and business model of American public universities are changing? Visit a place like Indiana University. Five years ago, there were 87 undergraduates from China on its idyllic, All-American campus in Bloomington. This year: 2,224.

New figures out Monday show international enrollment at U.S. colleges and universities grew nearly 6 percent last year, driven by a 23-percent increase from China, even as total enrollment was leveling out. But perhaps more revealing is where much of the growth is concentrated: big, public land-grant colleges, notably in the Midwest.
