Yes, it would be nice to be able to elaborate on the statistics a bit more, although this is probably beyond what is practicable.

It's possible to infer or guess a few further details by knowing who someone's employers are, but what I would find really interesting would be some background on voluntary developers, which must be quite a diverse demographic - long-term veterans, consultants expanding their credentials, professional students (probably the highest figure), developers migrating from another project, hobbyists etc. It might give further clues as to why this statistic has dropped, too.

I suppose this would be a lot too complicated to compile though. How are the 'none' and 'unknown' stats arrived at?

"None" is people known to be working on their own time - usually known because they told us so. "Unknown" is people we have no clue about.

Do you only use the email address to know who someone's employers are?
I ask this question because I looked at the "User namespace" patch from Serge E. Hallyn (link).
His email is serge AT hallyn DOT com but the status page for "User Namespace" is here in the Ubuntu wiki and the git development tree is in here at

I would like to know if Serge's commits are attributed to Canonical in your kernel stats.

An awful lot of developers do not post from company email addresses; if all we did was look for corporate domains, we'd have an awful lot more unknowns than we do. For your specific question: yes, Serge's contributions are properly attributed.
