<p>The data I posted are for the freshman admissions years. The 2008 data is for the most recent freshman class to enroll (fall 2008). I did notice that the application numbers on IPEDS for Dartmouth and Columbia were exactly the same in 2006 and 2007, which seems strange. </p>
<p>Using the preliminary 2009 numbers, here is the percent change over the most recent 5-year period 2004-2009. For Columbia, I substituted their 2008 number.</p>
<p>Cornell University 64%
Brown University 63%
Princeton University 60%
Dartmouth College 53%
Harvard University 48%
Yale University 46%
University of Pennsylvania 25%
Columbia University in the City of New York 23%</p>
