This project explores the demographics of the characters who make the yearly rankings of the top 100 most popular pairings on wellknown fanfiction site AO3. Its aim is to raise awareness about the work of the highly female-dominated author base of fandom, explore how fans choose to interact with mainstream media, and to provide visualisation and statistical insight for and about a topic and community that does not have as many members who code as more male-dominated ones do and therefore is less well-documented.
