The number of foreign students enrolled at American colleges has increased nearly 73 percent since the 2005-6 academic year. That influx has meant three-quarters of the colleges have more foreign students today than they did 10 years ago. However, some institutions — like Arizona State University and Northeastern University — have absorbed far more than most others, adding foreign students at four to six times the national rate.
The numbers of foreign students studying at American colleges come from the Institute of International Education's 2006 and 2015 reports. Using those figures, our analysis calculated how many out of every 1,000 foreign students studying in the U.S. were at each college in the 2005-6 and 2014-15 academic years — what we termed the college's "share." Colleges with fewer than 10 international students in either academic year are excluded. For display, values are rounded, and small rounding errors may appear.
