For Black mathematicians in the United States, histories have frequently been fragmented or omitted from official records — an absence that itself constitutes a form of exclusion. The Black Math Census Project is a holistic quantitative effort to document, enumerate, and study Black mathematicians who have earned doctoral degrees in mathematics and related mathematical sciences in the United States. It grew from the 2025 MetaMath workshop at the American Institute for Mathematics (AIM), which convened researchers committed to using the tools of mathematics, statistics, and data science to study mathematical communities themselves.
Our current dataset centers Black women — constructing a curated, verified record of 147 Black women mathematicians — and we are actively expanding toward all Black mathematicians regardless of gender. By integrating archival research, institutional records, digital databases, and community knowledge, we have established a reproducible methodology for identifying, verifying, and documenting Black mathematicians. Our work transforms historical documentation into structured research infrastructure — a foundation from which questions of participation, institutional pathways, advising networks, and doctoral production can be studied rigorously.
More broadly, the framework developed here offers a model for constructing datasets that support the holistic, quantitative study of underrepresented communities within the mathematical sciences.
The mathematical community cannot effectively support, mentor, or advocate for its members without first knowing who they are. An incomplete historical record obscures contributions and unintentionally reinforces narrow perceptions of who belongs in mathematics.
The centennial of Elbert Frank Cox's 1925 PhD — the first awarded to a Black person in mathematics — created a natural occasion to examine Black mathematical communities. Modern archival tools make a holistic enumeration possible in ways previously unattainable.
We are building toward a complete census of Black mathematicians — women and men — who earned doctoral degrees in mathematics, applied mathematics, statistics, mathematics education, or related mathematical sciences at institutions in the United States (and a small number internationally).
All visualizations below are based on our current dataset. Data are presented in de-identified, aggregate form. No individual names or identifying information appear. The dataset continues to grow as new records are identified and verified.
55% earned their bachelor's degree at an HBCU.
Every institution awarding 3+ bachelor's degrees
to future Black math PhDs is an HBCU.
The Black Math Census Project builds on over four decades of community-led efforts to document Black mathematicians. Our work would not be possible without those who came before us.
The Black Math Census Project is both an act of historical preservation and a contribution to an emerging scientific program. The 2025 MetaMath workshop at the American Institute for Mathematics (AIM) brought together researchers interested in using mathematics, statistics, and data science to study the mathematical sciences community itself — a kind of mathematics of mathematics. Viewed through this lens, our dataset is research infrastructure: a foundation for quantitative investigation of doctoral production, institutional pathways, academic genealogy, mentorship networks, geographic mobility, and professional trajectories.
These questions can be studied using a broad range of mathematical and computational techniques, including statistical analysis, network science, graph theory, machine learning, data visualization, and other methods from the mathematical sciences.
More broadly, this work illustrates one way in which MetaMath contributes to the emerging field of quantitative justice. Quantitative justice seeks to address societal issues related to inequity using rigorous theoretical and applied mathematical tools. Its framework begins with societal questions and develops rigorous mathematical methods to investigate them. The societal issue motivating this project concerns the historical participation and representation of Black mathematicians. By counting and documenting this community, we create tools capable of facilitating rigorous models of the mathematical sciences.
Our growing dataset of Black women mathematicians provides a foundation for future mathematical research while simultaneously preserving the history of Black mathematicians and making that history more accessible to researchers, educators, professional societies, and the broader public. Thus this work serves not only as a foundation for MetaMath research on the mathematical sciences community, but as a novel approach to quantitative justice research — modeling how archival scholarship, mathematics, statistics, and data science can work together to address broader questions of equity, participation, and representation.
Continuous improvement of methodology using commencement records, graduate school archives, dissertation databases, department records, professional association archives, obituaries, and biographical collections.
Long-term trends in doctoral production by Black mathematicians — identifying periods of growth or stagnation, and the institutional and societal factors associated with those changes.
Tracing advising relationships and influential mentoring communities to understand how knowledge, opportunity, and professional support are transmitted across generations of mathematicians.
Documenting the contributions of Black women mathematicians across academia, industry, government, education, and other sectors — informing future mentoring initiatives and broadening-participation efforts.
The most important thing you can do is help us find people we have missed. Our dataset is built on archival research, institutional records, and community knowledge. We know our list is incomplete.
If you know of a Black mathematician who earned a doctoral degree in mathematics or a related mathematical science in the United States — including yourself — please share that information with us using the form below. Our current dataset focuses on Black women, and we are actively expanding toward all Black mathematicians regardless of gender. All submissions are reviewed and verified by our research team before inclusion.
We record doctoral degree year and institution, dissertation title, primary advisor, undergraduate institution, and research area. All data in our public-facing work is de-identified and presented in aggregate.
Black mathematicians — women and men — who earned a PhD in mathematics, applied mathematics, statistics, mathematics education, or a closely related mathematical science at a U.S. institution (or international institution). Any year, any era. Our current dataset centers Black women; we welcome submissions about all Black mathematicians as we grow.
We welcome collaboration with university math departments, graduate schools, and HBCU mathematics programs. Commencement records, department histories, and institutional contacts are especially valuable.
We are building research infrastructure, not just a list. We welcome collaborations with historians, sociologists, data scientists, and mathematicians interested in MetaMath and quantitative justice research.
The absence of data is itself a form of exclusion. Join us in building the most complete record of Black women in the mathematical sciences ever assembled.
The Black Math Census Project has been announced to the community through newsletters of the Association for Women in Mathematics (AWM) and the National Association of Mathematicians (NAM). The research article describing the full dataset and methodology is now available as a preprint on arXiv. This work was supported in part by the National Science Foundation under Grant No. DMS-2138110 and HHMI Gilliam Grant Number GT16840.
For Black women in the mathematical sciences, histories have frequently been fragmented or omitted from official records, an absence that itself constitutes a form of exclusion. This project addresses this critical gap by constructing a curated dataset of 147 Black women who have earned doctoral degrees in mathematics and related mathematical sciences in the United States. By integrating archival research, institutional records, digital databases, and community knowledge, we establish a reproducible methodology for identifying, verifying, and documenting Black women mathematicians.
We situate this dataset within a broader history of efforts to document Black mathematicians and describe how prior archival and community based initiatives informed its development. We then demonstrate the utility of the dataset through exploratory analyses of doctoral production, institutional pathways, undergraduate preparation, mentorship networks, and research areas. This revealed patterns including large concentrations of doctoral production among a small number of institutions and advisors. Additionally, our analysis highlights the vital role of Historically Black Colleges and Universities (HBCUs) in preparing Black women who have earned doctoral degrees in the mathematical sciences.
By transforming historical documentation into structured research infrastructure, this work provides a foundation for future investigations of mathematical communities using historical as well as mathematical, statistical, and computational methods. More broadly, the framework developed here offers a model for constructing datasets that support the study of underrepresented communities within the mathematical sciences.
Our work builds directly on the following foundational contributions to the documentation of Black mathematicians.
