New Reports from November 2008 Survey Released
In November 2008, the Collaborative Creativity Group at UNU-Merit, in partnership with the Wikimedia Foundation, launched the most comprehensive survey of Wikipedia readers and contributors ever conducted. The survey was translated into 20 languages and received more than 170,000 responses. In April 2009, we shared preliminary results of the survey, and in August 2009, a member of the UNU-Merit team presented the survey at Wikimania (slides are available online).

Only 13% female :o That’s a surprisingly big imbalance. Very interesting stats :)
A very interesting post. An huge research effort is focused in editors, but nothing is said about readers. Thanks.
I’ve found a ton of inconsistencies in these UNU data. Unfortunate.
