My apologies if it’s stating the obvious or a point made elsewhere, but one difficulty with this approach is students may actually prefer a lower ranked law school if closer to where they expect to live. For example, 17% of Carleton students come from Minnesota and about 37% come from the Midwest overall. I can absolutely see how a student from MN or the broader Midwest would prefer to attend #16 Minnesota over #14s Georgetown or Cornell. Unsurprisingly, Minnesota’s law school is easily the most popular destination for Carleton alumni.
A second problem is collecting data from LinkedIn does not appear reliable. I commented on this in the similar med school thread but it appears in the case of Carleton almost 90% of their relevant alumni were missed in the tally. I will attempt to link to that post below.
