Github Demographics

For the past couple weeks I’ve been working on a project to visualize and compare the demographics of popular GitHub organizations by combining data from the the RapLeaf and GitHub APIs.   By pulling emails from Git commit data and querying the Rapleaf API for demographic data, I was able to put together an aggregate picture of the age + gender + income of people who have contributed to a GitHub organization (shown below for the Rails organization)

• See more details on how the data was gathered here,
• See organization ranked by age / gender / income here
• Browse all available organizations here.

I’ll be following up soon with some thoughts on the results.  For now, I’ll just point out that Linux kernel developers make serious bank.
