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.

The numbers offer a snapshot of the transformation of America’s famous heartland public universities in an era of diminished state support. Of the 25 campuses with the most international students, a dozen have increased international enrollment more than 40 percent in just 5 years, according to data collected by the Institute of International Education. All but one are public, and a striking number come from the Big Ten: Indiana, Purdue, Michigan State, Ohio State and the Universities of Minnesota and Illinois. Indiana’s international enrollment now surpasses 6,000, or about 15 percent of the student body, and in Illinois, the flagship Urbana-Champaign campus has nearly 9,000 – second nationally only to the University of Southern California.
