When you search for someone notable on the internet, one of the first things that often pops up is a link to their Wikipedia page. But if you’re looking for a notable woman, that might not be the case. There are about 1.5 million biographies on Wikipedia. Only about 19% of them are about women. And those that do get published are much more likely to be targeted for deletion, compared to biographies of men. That’s according to research by Francesca Tripodi, a professor of sociology at the University of North Carolina at Chapel Hill. Marketplace’s Kimberly Adams speaks to Tripodi about her recent paper, “Ms. Categorized: Gender, notability, and inequality on Wikipedia.”
