The National Science Foundation keeps track of the doctorates granted by US universities each year. In this post, I’ve mapped recipients of doctoral degrees in 2012 (the most recent data available) by state and country. The top map shows the number of doctorates granted in each state, as well as the 20 universities that graduated the most doctoral students. The bottom map illustrates the citizenship of the students who received their doctorates in the USA. All countries that had at least 50 students are shown.

Both maps are influenced by population density, but there are some interesting outliers. The list of the 20 universities producing the most doctoral students may also surprise you…
