I am trying to compile some demographic data on who has contributed to Bitcoin so far and track how the demographics are changing over time.
Since GitHut does not show me demographic data I have attempted to use Google with limited success.
What is the age of the oldest known Bitcoin person to submit a pull request to Bitcoin core? I asked the same question about the youngest person the other day and the answers were helpful to me.
Eventually I want to try to compare the mean and median ages (and sex) of users and developers and track the changing demographic trends of each group.
