If you take a stroll around the University of Texas at Arlington campus, a fact reported this week by U.S. News & World Report becomes quite obvious: UT Arlington is one of the most ethnically diverse campuses in the country.The national magazine, which annually ranks colleges and universities in various categories, placed UT Arlington at No. 5 among the nation’s most diverse in its 2014 rankings, up from No. 7 a year ago. The “diversity index” as defined by the magazine, is based on where college-bound students seeking diversity “are most likely to encounter undergraduates from racial or ethnic groups different from their own.”This latest accolade is not a real surprise because for years the fast-growing local university has attracted students from various backgrounds, as well as from many different countries, although international students weren’t used as a factor in U.S. News’ study.Among UT Arlington’s more than 33,300 students, ethnic minorities make up 46 percent of the enrollment, and international students are 9.3 percent of the population. This semester Hispanics represent 22 percent of the student body; blacks, 14 percent; and Asians, 10 percent. The students come from every state in the nation and 116 countries.The university, which in recent years has embarked on an aggressive capital improvement program along with greatly enhancing its academic curricula, had the highest diversity ranking of any school in North Texas, and was ranked second behind the University of Houston among the five Texas universities in the top 25. Also on the list were Rice, Texas Woman’s and the University of Texas at Dallas.The diversity ranking wasn’t the only praise U.S. News had for UT Arlington. The university’s undergraduate business school, ranked 141 last year among 388 similar programs, shot up to No. 119 in this year’s listing.Again, no surprise there in that the UT Arlington College of Business has been in a serious upgrade mode for several years. Congrats are in order to UT Arlington for another couple of great milestones.
