Here's a bullet point that I did research on earlier today. I had an impression in my mind that Tuck is a very North East / New England focused school and that most of the alumni/students are from there/end up there when they graduate. I found that only 50% of Tuck's graduates end up in New England or the NYC area upon graduation, and the rest are spread out throughout the country and the world. I plan to return to California when I graduate, so the West Coast %s were something that I paid attention to personally.
Tuck's class last year was 54% in the North East, 13% on the West Coast
HBS' class last year was 43% in the North East, 15% on the West Coast
Wharton's class last year was 47% in the North East, 16% on the West Coast
Chicago GSB's class last year was 31% in the North East, 30% in the Midwest, and 11.5% on the West Coast
Chicago's statistic really stuck out to me. I would have figured that Chicago has a stronger hold on the West Coast than Tuck does. I suppose that in sheer numbers - they do, but % wise, they are very similar.
I am convinced that Tuck can place you anywhere in the world - you will just have to work for it and you will have to make the effort to get outside of Hanover more frequently than others.
