Mapping Diversity – Full dataset release

Today we are releasing the full dataset behind Mapping Diversity, our investigation into the street names of cities across Europe, focusing on the individuals who get celebrated through them.

In this project, we mapped dozens of thousands of street names by bringing together data from OpensStreetMap and Wikidata. We automatically filtered and categorized street names, and then manually checked the records line-by-line in order to ensure accuracy. We started with 30 cities in 17 countries, with the aim of expanding the dataset over time, as we are currently doing. Today’s release already includes 6 more cities that we have been working on over the last few months, namely Ancona, Bologna, Florence (Italy), Munich (Germany), Sibiu (Romania) and Oslo (Norway).

For more information and to read all the stories that have come out of the analysis so far, you can visit this page.

As for the dataset, we initially kept it for our partners at EDJNet and a handful of selected external media and researchers, while only sharing aggregated data and a selection of detailed data publicly. As sharing knowledge and fostering collaborations is something we value highly, we are now finally releasing the full Mapping Diversity dataset, including all the street names that we have covered so far. We see this as a long-term project, so new cities will be added in the coming months and years. Keep an eye on our newsletter to find out when this happens.

You can find the full dataset, along with a separate metadata file, here. Other aggregated or filtered versions of the dataset are available here.

If you are interested in collaborating with us to add new cities to the database or to use the data for other purposes (analysis, visualisation, etc.), don’t hesitate to contact us at
