Between 1850 and 1910 the population of Vienna almost quadrupled, from about half a million, to two million. During this Golden Age of Science and Culture, more than half of the Viennese population came from outside Vienna, and a significant share came from outside what today constitutes Austria.

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.

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.
