<p>The National Science Foundation has given an exit survey (and maintained a database of responses) to every new academic doctorate recepient since 1920. Their survey captures well above 90% of all PhDs, Doctor of Divinity, Doctor of Music (or whatever that one is called). The entire database is available with a custom search engine on the internet (by field, by PhD institution, by undergrad institution, by gender, by race, and so on and so forth).</p>
<p>The NSF is primarily interested in science PhDs, but it’s difficult to fish for those without casting a net to survey all new PhDs.</p>
