The numbers on open source

Open source is eating the world
78% of companies use and 63% participate in open source.

Diversity in open source is even worse than tech overall
Women vs men developers, professional US (23%) and open source globally (4%)

Women are just as interested as men in contributing to open source, but are
2xas likely to have a
negative encounter
2xas likely to seek help
from people they already know

Impact is both personal and universal
“Half of contributors say that their open source work... [helped] get their current role”

Challenges
• Many unspoken rules in open source
• High barrier to entry in large projects
• Very few independent maintainers (70% are
employed)
