<p>Here’s what I went back and did with the numbers, to address the posters who think that the indexes mean “more kids from the Northeast are going out of region because look, they are indexing high in schools in some of the other regions.” This was bothering me because the actual # of schools in each region is different.</p>
<p>So here’s what I did.</p>
<p>I assumed each of these 22 top research universities had 10,000 students (just to make my math easy). I know that isn’t strictly true, but for our purposes that’s OK, unless someone wants to feed me the actual research university undergrad sizes.</p>
<p>Since I knew the %'s from each region at each school, I then went back and calculated the “raw numbers” of students from each region attending each college. Then I could sum them up different ways. Here’s what I found:</p>
<p>Assuming these students make up the universe of top students,
if I were to combine these students into one massive pool / uber-elite-university this is what I would find:
Northeasterners make up 42% of these students.
Midwesterners make up 16% of them
Southerners make up 21% of them
Westerners make up 21% of them
for a total of 100%.</p>
<p>If I compare them to the actual % of the population in each part of the country, I get these indexes:
Northeast 181, Midwest 74, South 66, West 91.
So … * it is true that Northeasterners disproportionately “fill the seats” of the nation’s elite universities*. The West is about average and the Midwest and South are below average.</p>
<p>HOWEVER … if I then look at these students and say “who stayed in their home region” and “who left home region,” here’s what I find:
73% of Northeasterners stayed in home region
45% of Midwesterners stayed in home region
31% of Southerners stayed in home region
31% of Westerners stayed in home region</p>
<p>In other words, Northeasterners (at least of the elite-school variety) are less likely to travel out of home region for their elite education compared to other regions.</p>
<p>The reason that this is, is simply because there are more “elite seats” in the Northeast region to begin with …
55% of “elite seats” are in the Northeast (8 Ivies plus MIT, JHU, CMU, Gtown)
18% of “elite seats” are in the Midwest (4 schools)
14% of “elite seats” are in the South (3 schools)
14% of “elite seats” are in the West (3 schools)</p>
<p>In other words - the people who kept saying “but this means NE’ers are more likely to travel outside home region” weren’t taking into account that yes, NE’ers are more likely than those in other regions to “sit” at an elite school, but those seats are also disproportionately * located* in the NE. </p>
<p>I’ll do the same with LAC’s at some point, but wanted to get the research university out there. </p>
