The University at Buffalo has posted its highest enrollment in almost seven years, markedly increasing its graduate-student population and pulling in one of the most academically talented freshman classes in years. A total of 25,838 students are enrolled at UB for the fall semester, an increase of slightly more than 1,000 from the Fall 2000 figure of 24,830. The university has increased graduate enrollment by 5 percent over the Fall 2000 figure, from 8,147 to 8,548, which Sean P. Sullivan, vice provost for enrollment and planning, called "the third-highest graduate enrollment in our history."
