From Inside Higher Ed we learn that National Science Foundation has stopped reporting data on numbers of minorities earning doctorates in some scientific specialties, if those numbers fall below a certain threshold. The Survey of Earned Doctorates (SED), an annual survey of doctoral awardees conducted for NSF and five other federal agencies by the National Opinion Research Center, no longer reports data for table cells where the reporting of small numbers in those cells may divulge personal or confidential information.
According to the most recent (2006) report (PDF), this non-reporting of data removes much of the data on Native American participation in the sciences. Likewise, data for African-Americans in several disciplines ...
Earth, atmospheric, & marine sciences
- Physics & astronomy
- Aerospace/aeronautical engineering
- Industrial engineering
are gone as well. See the screen shot below; cells with "D" have the withheld data.

Inside Higher Ed quotes an e-mail from Jaqui C. Falkenheim, NSF's project manager who attributed the decision to a review by NSF's Division of Science Resources Statistics (SRS) that publishes this and other workforce statistical reports. She said, "The findings of that review revealed the need, given more restrictive rules/guidelines and heightened concerns about confidentiality/privacy, to tighten SRS procedures for releasing SED data to the public." Falkenheim adds that protection of confidentiality helps keep response rates high and protects "the reputation of NSF as a research partner with academe".
How large does the cell size need to be to allow release of data? According to Falkenheim and Inside Higher Ed, that's confidential as well.
Users of these data are both disappointed and mystified. "This hides information. It removes information," said Andreen Neukranz-Butler, human rights compliance officer for the University of Idaho. She also noted that even with small cell sizes, no names or institutions are revealed, thus the concerns about confidentiality don't add up.
One of the commenters on the InsideHigherEd site, a researcher at University of California-Berkeley remarked, "This latest move is utterly pointless, indeed counter productive. It seems yet another move intended to obscure the very slow growth of Ph.D. acquisition by ethnic minorities."
Science Careers asked Falkenheim to comment further;
we will update this post with NSF's response.
