State College, home to Penn State's University Park campus, has been ranked third-best among college towns for college students by the American Institute for Economic Research (AIER). The rankings appeared in AIER's recently released 2012-13 College Destinations Index (CDI), an annual quantitative ranking of the nation's 75 best towns and cities to live in if you're a college student. The index takes into consideration such aspects as academic environment, quality of life and professional opportunity. College towns are those with a residential population under 250,000. The locations were chosen from an analysis of the 227 U.S. metropolitan statistical areas (MSAs) with student populations of 15,000 or more. Among the 227 MSAs, State College also ranks as the third-best overall college destination.
