Editor’s note: The author of this post is Rhiannon Ruff (User:Grisette) and is part of a series on female editors of Wikipedia. Her most recent post—the first in the series—was “All The Women Who Edit Wiki, Throw Your Hands Up At Me” on November 8, 2012.

Continuing this series on women and Wikipedia, this week I’d like to give a quick overview of the gender gap and its impact. Let’s start with what we already know: female Wikipedia editors are in the minority of those making edits to the site’s articles and Talk pages on a regular basis. Earlier this year, a research project by Santiago Ortiz found that on average there are 12.9 male editors to each female editor editing a given article. This is an issue that Wikipedians are very familiar with. For many, the real concern is not just that women aren’t participating, but that their relative absence may have led to gaps in Wikipedia’s collective knowledge.

In early 2011, Noam Cohen wrote an oft-cited article for the New York Times which made the point that Wikipedia’s coverage of topics more likely to be of interest to women tended to be much less well developed than for corresponding topics of interest to men. Indeed, anecdotal evidence exists for a gendered take on notability: in some cases, articles on female-oriented topics have been nominated for deletion, not considered “notable” by (mostly) male editors. In particular, Torie Bosch wrote on Slate.com about the deletion debate around the Wikipedia article Wedding dress of Kate Middleton, which survived after editors including Jimbo Wales fought for it to remain. Bosch also described how several new articles on female historical figures created during a Smithsonian archives “edit-a-thon” were later nominated for deletion—one more than once.

(As an aside: I personally find it offputting how this gender gap topic is often addressed. For instance, Cohen’s article specifically mentions the poor state of the articles on the TV series Sex and the City and fashion designer Jimmy Choo as indicators of missing female editors. Examples like these are more than a little patronizing and hard to take seriously. I’m not the only one who feels this way.)

The gender gap doesn’t just affect what articles get created (and don’t get deleted): the quality of certain articles may be affected by the dearth of female editors, too. In January 2011, Wikipedia’s newsletter, The Signpost, included a piece in which Wikipedia article quality was compared between the most famous male and female scientists from Science magazine’s Science Hall of Fame. The author of the Signpost article found that the top ten male scientists’ articles are mostly rated a “B” on Wikipedia’s article quality grading scheme, and include one Good Article and one Featured Article, while the top ten female scientists’ articles are all rated Stub or Start class (with the exception of Marie Curie). Worth noting: the author explained the conclusion isn’t a clear cut case of gender imbalance, since the female scientists were generally less well-known than the men, which could have an impact on both number of editors interested in the articles and availability of material to improve them.

An interesting question in light of all the above: what exactly are women editing on Wikipedia? If we look at one of Wikipedia’s most well-known female editors, SlimVirgin, who’s had a key role in 10 Featured Articles—no mean feat—we can get an idea of what a prolific female editor works on. Her Featured Articles span a range of topics, from the biographical article for Palestinian political leader Abu Nidal to the article on the Brown Dog Affair, an Edwardian-era political controversy about vivisection. No obvious gender bias here. Nor is there any big difference between male and female editors in terms of types of edit according to a 2011 study titled Gender Differences in Wikipedia Editing. The study’s authors found there was no evidence that men and women tend to make different sized edits or that one gender prefers fixing text to adding new text. In short, it seems the gender gap issue isn’t as simple as “get female editors, solve knowledge gaps”; it may have a lot to do with the types of article or information that people drawn to Wikipedia editing are most interested in. (Yes, I’m saying that Wikipedia editors are likely to be more interested in Linux than dresses, sorry Jimmy Wales!)

While writing this post I was intrigued to see if picking 10 editors at random from the Female Wikipedians category and looking at their most recent edits would provide any insight. Disappointingly, seven out of the ten hadn’t edited in over two years, and of the remaining three only one had made an edit in article space in the last year. This result is certainly indicative of Wikipedia’s broader problem of editor retention, but it also speaks to the particular issues Wikipedia has had retaining female editors. Which leads nicely to the topic of my next post… the issues involved in recruitment and retention of female editors. Look for that here soon, meanwhile (for U.S. readers) have a wonderful Thanksgiving!
