Diversity & Inclusion in Scientific Computing (DISC)

DISC Program Mission

NumFOCUS recognizes that the open source data science community is currently highly homogenous. We believe that diverse contributors and community members produce better science and better projects. NumFOCUS strives to help create a more diverse community through initiatives and programming devoted to increasing participation by and inclusion of underrepresented people.

NumFOCUS Diversity Statement

NumFOCUS welcomes and encourages participation in our community by people of all backgrounds and identities. We are committed to promoting and sustaining a culture that values mutual respect, tolerance, and learning, and we work together as a community to help each other live out these values.

For a more detailed explication of NumFOCUS’s position on diversity in the community, see the Diversity Appendix.

Get Involved

We invite the community to learn more about DISC initiatives by joining the DISC community mailing list

Code of Conduct

We expect all NumFOCUS community members to abide by the Code of Conduct.


The DISC Committee has worked to curate a community-authored cookbook on how to organize diverse and inclusive events, called the DISCOVER Cookbook (Diverse & Inclusive Spaces and Conferences: Overall Vision and Essential Resources).

We encourage the community to make use of, and contribute to, this great resource!
