<p>We’ve all know about the situation with the greatly increased numbers of top high school students looking for spots among the relatively constant number of freshmen places at America’s most historically prestigious colleges. This collision has boomeranged to the benefit of many colleges just outside of the highest tier of HYPSM, resulting in a broad improvement in the overall statistical strength of many collegiate student bodies. I call this the “elite-pie-is-growing” effect. Contrary to some, I actually think that this works to the benefit of top students all across the USA as they are now learning about and attending a greater breadth of colleges than ever before and realizing that there is great quality to be found in all regions of the country. </p>
<p>I looked closely at the change in the primary data points that USNWR uses in evaluating student body strength and how these numbers have changed since 1991. While the numbers below only relate to colleges that were ranked in the USNWR Top 25 in both 1991 and 2008, I think we would all agree that the "pie-is-growing effects also extend much further down the rankings. Here are the results:</p>

<p>I think it should also be noted that the changes in Acceptance Rate were even more severe for this most recent year and some of these colleges saw their rates go sharply lower. This is likely influenced by the more recent trend of each student submitting more applications to more top schools than ever before, a trend that was exacerbated by the elimination of early programs at Harvard, Princeton and U Virginia.</p>
