How many women edit Wikipedia?

The following content has been republished from the Wikimedia Blog. The views expressed in this piece are those of the author alone; responses and critical commentary are invited in the comments section. For more information on this partnership see our content guidelines.

The month-long "Inspire" campaign seeking ideas for new initiatives to increase gender diversity on Wikipedia recently concluded successfully, with hundreds of new ideas and over 40 proposals entering consideration for funding. During this campaign, there were a lot of questions about the empirical basis for the statement that women are underrepresented among Wikipedia editors, and in particular about the estimate given in the campaign’s invitation banners (which stated that less than 20% of contributors are female). This blog post gives an overview of the existing research on this question, and also includes new results from the most recent general Wikipedia editor survey.

The Wikimedia Foundation conducted four general user surveys that shed light on this issue, in 2008 (in partnership with academic researchers from UNU-MERIT), 2011 (twice) and 2012. These four large surveys, as well as some others mentioned below, share the same basic approach: Wikipedia editors are shown a survey invitation on the site, and volunteer to follow the link to fill out a web-based survey. This has been a successful and widely used method. But there are some general caveats about the data collected through such voluntary web surveys:

Still, these caveats do not change the fact that the results from these web-based surveys remain the best data we have on the problem. And the overall conclusion remains intact that Wikipedia’s editing community has a large gender gap.

What follows is a list of past surveys, briefly summarizing the targeted population and stating the percentage of respondents who responded to the question about their gender with female in each. In each case, please refer to the linked documentation for further context and caveats. Keep in mind that the stated percentages have not been corrected for the aforementioned participation bias, i.e. that it is likely that many of them are several percent too low, per Hill’s and Shaw’s result.

General user surveys





Other surveys

There have also been several surveys with a more limited focus, for example:

Note: In this survey, the ratio of female editors was much higher than in the 2011 and 2012 surveys, in those countries where data is available. However, it is plausible that this difference can largely be attributed to different methodologies rather than an actual rise of female participation across the Global South.
