The Missing 78%: What We Learned When Our Community Doubled Overnight
2025-11-08 , Talk Track 1

Women make up only 22% of data and AI roles and contribute just 3% of Python commits, leaving a “missing 78%” of untapped talent and perspective. This talk shares what happened when our community doubled overnight, revealing hidden demand for inclusive spaces in scientific Python.

We’ll present the data behind this growth, examine systemic barriers, and introduce the VIM framework (Visibility–Invitation–Mechanism) — a research-backed model for building resilient, inclusive communities. Attendees will leave with practical, reproducible strategies to grow engagement, improve retention, and ensure that the future of AI and Python is shaped by all voices, not just the few.


Women represent only 22% of data and AI roles and contribute just 3% of Python commits, leaving a “missing 78%” of untapped talent and perspective. This imbalance isn’t just a diversity issue — it risks embedding bias into the foundations of AI and scientific Python.

In this talk, I share what happened when our community doubled overnight, a case study that uncovered hidden demand for more inclusive spaces in open source. Using a mixed-methods approach — combining membership data, demographic surveys, and qualitative feedback — we examine what drives rapid growth and, more importantly, what sustains it.

The core of the talk introduces the VIM framework (Visibility–Invitation–Mechanism), a research-backed model for building inclusive and resilient communities. We’ll explore how visibility (who gets seen), invitation (who feels welcome), and mechanism (what support exists) can be applied in practical, repeatable ways to unlock hidden demand and improve retention.

Attendees will learn:

  • Why inclusive design is critical for sustainable growth in AI/Python communities

  • The data-driven lessons from a 179% membership surge in one day

  • Practical, actionable strategies to apply the VIM framework in their own projects

This session combines research and practice to provide attendees with both insight and a toolkit for building stronger, more inclusive communities.
