openhub.net (formerly ohloh.net) has an interesting comparison of the number of public repositories on the net, based on searches of popular hosting services. This comparison is available at <https://www.openhub.net/repositories/compare> and shows an estimated market share between Bazaar, CVS, Git, Mercurial and Subversion. I've been monitoring this since 2014-08-05 to see how things were developing, and it's a good indication of the popularity of the various version control systems. I've created a repository at <https://github.com/sunny256/openhub-repositories> where the project scripts and data files are stored, along with graphs in SVG format. The graphs are pretty interesting: https://github.com/sunny256/openhub-repositories/blob/master/graph/relative.svg Graphs of relative growth between the various version control systems. https://github.com/sunny256/openhub-repositories/blob/master/graph/relative-zoom.svg Zoomed-in version of relative.svg. Git goes through the ceiling. https://github.com/sunny256/openhub-repositories/blob/master/graph/repos.svg Total number of repositories.
number of repositories is an interesting datapoint, but activity in the repos would be far more interesting. There are a lot of repos of various types out there that haven't been touched for years.
