The Leaky Pipeline into Academic Philosophy for Black Students in the U.S.

Liam Kofi Bright, Carolyn Dicey Jennings, Morgan Thompson, Eric Winsberg and I have a paper forthcoming in The Philosophers' Magazine on the racial, ethnic, and gender diversity of philosophy students and professors, and how it has changed since the year 2000.  We look at data from first-year intention to major through entry into the professoriate, drawing on several large data sources.

Below is a teaser, with graphs on the percent of philosophy majors who are non-Hispanic Black at three educational levels: first-year intention to major, completed bachelor's degree, and completed PhD, from 2000-2001 through the most recent available year.  In each figure, the heavy black line represents the percent of philosophy majors who identify as non-Hispanic Black and the gray line represents the percentage of non-Hispanic Black students in all other majors combined.  If the figures don't display correctly, click to enlarge and clarify.

In this first figure (drawing on the HERI CRIP database), note the sharp increase in first-year intention to major from 2000 to 2016.  By the end of the period, first-year students intending to major in philosophy are about 10% non-Hispanic Black, similar to their overall representation in the undergraduate population.

How about bachelor's degrees awarded?

Here (drawing on the NCES IPEDS database), things are quite different.  It does appear that the percent of philosophy bachelor's recipients identifying as non-Hispanic Black is rising -- from about 4% in the early 2000s to about 6% more recently.  But it still remains far below the 10% non-Hispanic black among bachelor's recipients overall.  This might partly reflect a lag in the data.  Students entering in 2015 or 2016 (the final two years of the first figure) wouldn't normally be receiving their bachelor's degrees by 2019 (the final year of the second figure).  Other possible explanations include a tendency for Black students disproportionately to exit (or not enter) philosophy, difference in the questionnaire items or methods, or sampling problems in the HERI database.

We see further falloff at the PhD level (drawing on the NSF SED database):

Non-Hispanic Black students are currently receiving only 1-4% of PhDs, with a weakly increasing trend at best.  Temporal offset might again play a partial role, but it can't be the whole story.  Even if we take bachelor's recipients from 2010 and 2011 as the approximate cohort to receive PhDs in 2018 and 2019, there's a falloff from about 5% to about 3%.  It's unlikely that sampling problems could explain the difference, since both datasets capture the large majority of degree recipients.

The most natural explanation is a "leaky pipeline".  Philosophy is increasingly drawing Black students' initial interest.  However, for whatever reason, as their education proceeds from first-year to bachelor's to PhD, Black students are disproportionately likely to exit.
