<p>Midd, Williams, and Bowdoin are located in relatively isolated corners of New England, and tend to attract outdoorsy, athletic students, as does Dartmouth. Swarthmore is located in a suburb of Philadelphia, and has a more urban and nerdy feel. Swarthmore is clearly more distant from Dartmouth, in terms of both geography and campus culture, than the other LACs on your list.</p>
<p>Williams and Swarthmore are about as academically selective as Dartmouth. Bowdoin and Midd are slightly less selective, but not by much.</p>
<p>Dartmouth is noted for its small class sizes and commitment to undergraduate education; however, the LACs on your list match or surpass Dartmouth in these regards. Williams, for example, is well known for its tutorial classes, where enrollments are capped at two. Williams and Swarthmore are actually wealthier than Dartmouth, on an endowment-per-student basis. The LACs, unlike Dartmouth, don't support graduate and professional schools, which reduces their expenses-per-student as well.</p>
<p>One of the biggest differences is social life. Dartmouth social life is dominated by an extensive Greek system, with single-sex frats and sororities. This leads to a more gender-segregated social environment, with separate (though not necessarily equal) opportunities for male and female students. Dartmouth frat parties are legendary, though if you are on the "quieter side" this may not be what you are looking for.</p>
<p>The LACs, in contrast, are thoroughly integrated. Midd, Williams, and Bowdoin have banned Greek organizations completely; Swarthmore still has a few frats, but they don't dominate the social scene. </p>
<p>Dartmouth has NCAA Division I athletics; the LACs are all NCAA Division III. Williams and Midd rank consistently at the top of Division III, Bowdoin is competitive, Swarthmore is way behind.</p>
<p>All of these schools generate very loyal graduates, as shown by their high alumni giving rates. All of the schools on your list have giving rates between 50% (Dartmouth) and 58% (Williams). There are only a handful of other schools in the country that can count on half of their alumni to send in a check in any given year.</p>
<p>All of the schools do a great job of placing their graduates in top jobs or professional schools. For example, the Wall Street Journal recently ranked colleges for professional school placement; they put Williams, Dartmouth, and Swartmore in their Top 10, and Bowdoin and Midd in the Top 25.</p>
