What's Your Map?

Jerry meets Bill Rankin, a cartographer, author and Professor of History at Yale University. In this episode of What’s Your Map? they discuss two fascinating infographic maps that feature in Bill’s latest book Radical Cartography: What Maps Tell Us About Who We Are (2025). 

Radical cartography uses the method of mapmaking as a tool to challenge and educate on social, cultural, and political affairs. Radical maps are thematic maps that aim to give agency to the people who are represented within them and better show the nuanced world we live in. 

The first map they discuss was designed by civil servant and activist Gwendolyn Warren in 1971. Titled ‘Where Commuters Run Over Black Children on the Pointes-Downtown Track’, the map documents the racial inequalities of a Detroit neighbourhood and is designed to inspire change.

The second map, titled ‘A Taxonomy of Transitions’ shows the ethnography of Chicago and was made by Bill in 2010. It was created using self-identification government census data and illustrates the relationships of the different neighbourhoods in the city. This map harnesses the power of infographics to better represent the people who live in the area and create a boundary-less community. 

From historians, scientists and writers, to creatives and cultural custodians, people have used maps as a source of knowledge, guidance, and inspiration for centuries. 

Join us as map historian Jerry Brotton invites each guest to share a map close to their heart - and unfurl the ideas, inspirations, and personal stories behind it.
