Which countries contribute the most to the Tor source code?

Question

Amongst the developers working on the Tor source code, which countries have the maximum representation in terms of number of contributors and overall contributions?

Answer 1

I used git plus some shell to count the number of commits (git log --shortstat | awk -F: '/Author: / { print $2 }' | sort | uniq -c | sort -n). According to that more than 14000 commits came from Roger or Nick. This accounts for >80% of all commits (>17000). Some 1500 come from german speaking regions (Germany, Austria, Switzerland). There are 122 different names and email addresses committed some code. Most of them seem to come from the US.

I would guess that somewhat around 85% of the commits comes from the US, 9-10% comes from german speaking countries.
