How can car traffic in cities be reduced? New research by CSH's @rafaelprietocuriel.bsky.social shows that while metros are effective in reducing car traffic, a study of nearly 400 European cities finds no evidence that trams have the same effect: csh.ac.at/news/metros-...
Metros Cut Car Use In European Cities – Trams Fall Short
People drive significantly less in European cities with a metro system than in cities that only have trams or no rail-based public transport at all.

Sometimes old school really is such a cool way to explore data! No screens, no VR – but puzzles 🧩 and pop-up cards 💌.
This week, CSH data visualization specialist Liuhuaying Yang presented some of her projects at the IEEE VIS 2025 conference. And she decided to go full hands-on.

Why did Western democracies become so polarized? CSH researchers may have uncovered a piece of the puzzle. In a @pnas.org study, they show that between 2008 and 2010 polarization surged. At the same time, the number of close social contacts doubled:

Between 2008 and 2010, people’s average number of close friends rose from two to over four. At the same time polarization increased.

Why do some U.S. #cities thrive while others decline? According to a CSH study published in @pnas.org, the answer lies in economic “coherence”—a measure of how well the economic activities of a city fit together. 👉 shorturl.at/9YTIM
