According to the U.S. Census, there were almost 2 million more Americans between the ages of 15-19 in 2010 than in 2000 (see Table 2 in http://www.census.gov/prod/cen2010/brief...0br-03.pdf). That's a lot more U.S. applicants applying to college in 2010-2014 than in 2000-2004.
The two million change you note is 10%, and certainly the numbers of 18 year olds has fluctuated that much and more over the past 70 years. The numbers were largest from those born late 1950s to early 1960s. There hasn't been any increase in the number of 18 year olds that approaches the more than four fold rise in the applications to Stanford and other top schools.
Here is a graphic of year by year births in the USA.
Be careful looking at that chart - zero is not included on the y-axis.
Quote:Second, the number of international applicants (and acceptances) has been steadily rising, and I believe disproportionately to the top schools.
Almost certainly foreign applications have been rising from what I have heard, though as far as I can tell nobody reports those numbers. Stanford's latest common data set lists 128 foreign undergrads in the entry class of 2014-15, or 7.6%. My memory as one of those students from the mid-80s was that they told us we made up some similar fraction, but that could be wrong. The number from 10 years ago was 95 (vs 128). That relative increase is big (35%) but since the absolute increase is small it doesn't have a large effect on domestic applicants.

Quote:Finally, I believe the numbers of applicants that are in the "top tier" has increased because of the proliferation of AP courses and standardized test prep, as well as greater sophistication of college counseling and prep in terms of extracurricular activities, essays, etc; i.e., students who would have been "second tier" 10-15 years ago look first tier today.
This is one crux of the matter - in particular trying to make sense of what it means.
If there has been a proliferation of resources - does that mean it's harder to get in or does that very availability make it easier? Probably means harder for some, easier for others.
More broadly, that harder for some - easier for others theme seems to be the case with respect to trends in the demographic breakdown of the student body at top schools. Apparently white, non-hispanic students make up 37% of the 14-15 class (see common data set). I cannot find numbers going back very far right now. Ten years ago that was 44%. I think 50 years ago it was much larger.
Clearly that implies harder for some - easier for others.
