On the Relationship Between the Developer’s Perceptible Race and Ethnicity and the Evaluation of Contributions in OSS

Results: We observed that (1) among the developers whose perceptible race and ethnicity was captured by the tool, only 16.56% were perceptible as Non-White developers; (2) contributions from perceptible White developers have about 6-10% higher odds of being accepted when compared to contributions from perceptible Non-White developers; and (3) submitters with perceptible non-white races and ethnicities are more likely to get their pull requests accepted when the integrator is estimated to be from their same race and ethnicity rather than when the integrator is estimated to be White.

Conclusion: Our initial analysis shows a low number of Non-White developers participating in OSS. Furthermore, the results from our regression analysis lead us to believe that there may exist differences between the evaluation of the contributions from different perceptible races and ethnicities. Thus, our findings reinforce the need for further studies on racial and ethnic diversity in software engineering to foster healthier OSS communities.
