It was really interesting to see who the editor community is, as this was our most comprehensive survey of editors.
As has been discussed recently, it is an important priority for the Wikimedia movement to progressively add diversity to our community. We have set targets in our strategy for greater participation of women and for rapid growth in the Global South. These actions seek to both increase the size of the community (our goal is to grow to 200,000 by 2015) and to bring important new knowledge to our projects.
With all of the options people have for occupying their time online and offline, we always wonder: why do people edit Wikipedia? One of the major answers: Editing Wikipedia is both fun in its own right and it feels really good sharing knowledge with the rest of humanity. Few, if any, people do this because it is part of their job or they are seeking some sort of personal benefit.
This is something anyone can do, after all Wikipedia is the encyclopedia anyone can edit.
