<p>Perhaps. Maybe IPEDS (or some other source) has those numbers.</p>
<p>I’ve seen PhD production numbers for economics adjusted for program size (in Siegfried & Stock 2006). It seemed to me that the institution-size-normalized lists were more plausible. The program-size-normalized numbers are even more skewed toward LACs and small regional universities (with MIT the only prestigious research university to make the top 25).</p>
<p>For mathematics, by my own estimates of program sizes (using the CDS section J numbers), Carleton appears to generate almost 2x as many math PhDs as Berkeley after adjusting for the number of majors. Reed appears to generate almost 3x as many as Berkeley.</p>
<p>Adjusting for institution size (not majors) will tend to favor schools whose departments attract relatively many majors. I would expect a high-quality program that motivates and prepares students well to attract relatively many majors, and also to produce a relatively high rate of earned doctorates. Of course, there can be various confounding effects (for instance, if many majors are heavily recruited into higher-paying careers than academia).</p>
