Recently I've been interested in quantifying the lack of diversity among geoscience graduate students. As a minority PhD student in this field, it was important to me to see just how many other URMs have come before me. Using publicly-available data from the NSF NCSES Survey of Earned Doctorates, I wrote a blog post and more recently a commentary in Nature Geoscience looking at the numbers. We found that not only was the geosciences the least diverse STEM field, but that the level of representation (among minority US citizens and permanent residents) had not improved between 1973 and 2016 (the range of the available data).
I had to jump through some hoops to get breakdowns by both gender and race/ethnicity, and since it didn't fit into the published Nature Geoscience commentary, I've included it in the table to the right.
