The Economics of Open Source Software

Who contributes most to Open Source software?

According to the United Nations University in 2006, it was Norway (measured per connection). The fact that it was a Northern European country did not come as a huge surprise. I've been using and sometimes contributing to open source software for the last 15 years and the number of Scandinavian names in the source code became humorous (of course, the contributors could have been from Minnesota :-).

The linked article says:

"Researchers compared the number of open source mailing list postings from different countries with the Internet penetration of each country. When ordered by this metric, Western Europe came out on top."

So, here's some original research. I wrote a short script that takes the surnames of the contributors from the actual code base. We can use these to give us a rough estimate of where the contributor comes from (sure, Minnesota and Sweden are going to be indistinguishable, but you get the idea).

The two sources I chose were Spring and Hibernate - two projects that are used extensively at the investment banks I've worked at these last 5 years.

The results are below. Feel free to use this script on your pet projects but please publicize the results if you can.

I asked an Indian QA friend of mine why there are so few Indian names - a surprise given India's large number of IT workers. He laughed and asked why anybody would work for free.
