When are prospective applicants taking the GMAT? To borrow a popular business school maxim: “That depends.” In 2019, the mean age varied from 23.9 (Mississippi) to 28.4 (Alaska), with U.S. military installations coming in at the 30.5. One trend is clear: MBA applicants are getting younger. Looking over the past four years, a dozen states have seen the mean age of test-takers be lowered by a year or more (with another seven states coming in at 0.8-0.9 lower).
