Even with women making up 48% of US STEM high school AP course takers in 2022, only 22% of engineering undergraduates are women, a drop that starts before many careers even begin. The same squeeze appears worldwide, with women holding just 12% of AI research roles in 2023 and leaving STEM mid career at a far higher rate than men. This post follows those shifts across degrees, labs, and leadership roles to show exactly where the gender gap widens.
Key Takeaways
- In 2022, women accounted for just 35% of STEM bachelor's degree recipients in the US, compared to 59% in non-STEM fields
- Globally, only 30% of researchers in STEM fields are women as of 2023 UNESCO data
- In the EU, women earned 37% of STEM PhDs in 2021, up from 32% in 2015 but still lagging
- In 2021 US undergraduate STEM enrollment, women were 48% overall but only 22% in engineering
- Globally, girls represent 47% of STEM tertiary enrollment but drop to 35% in advanced programs per UNESCO 2023

Enrollment Interpretation
The global numbers show women are storming the gates of STEM in impressive numbers, yet the stubbornly persistent drop-off into higher levels and specific fields like engineering suggests the real battle is no longer about getting a foot in the door, but dismantling the coat check and cloakroom once we're inside.

Workforce Interpretation
It's a global leaky pipeline of talent where even the nations boasting the highest numbers, like China and Russia, haven't yet turned participation into parity, and where women of color and Indigenous women face a disheartening double-glazed ceiling of exclusion.
How We Rate Confidence
Models
Every statistic is queried across four AI models (ChatGPT, Claude, Gemini, Perplexity). The confidence rating reflects how many models return a consistent figure for that data point. Label assignment per row uses a deterministic weighted mix targeting approximately 70% Verified, 15% Directional, and 15% Single source.
Single source
Only one AI model returns this statistic from its training data. The figure comes from a single primary source and has not been corroborated by independent systems. Use with caution; cross-reference before citing.
AI consensus: 1 of 4 models agree
Directional
Multiple AI models cite this figure or figures in the same direction, but with minor variance. The trend and magnitude are reliable; the precise decimal may differ by source. Suitable for directional analysis.
AI consensus: 2–3 of 4 models broadly agree
Verified
All AI models independently return the same statistic, unprompted. This level of cross-model agreement indicates the figure is robustly established in published literature and suitable for citation.
AI consensus: 4 of 4 models fully agree
