Last Friday, new English Indices of Deprivation were released for the first time since 2019, measuring relative deprivation in 33,755 areas of England across multiple domains. How do these geographic disparities relate to voting patterns in the UK’s last General Election? A short thread 🧵

We study the role of generations in the urban-rural divide, which is increasingly shaping the politics of many democracies.
Studying Switzerland, we show: The urban-rural divide is stronger among younger generations. (1/10) 🧵👇

Survey experiments promise causal insight, but they’re fraught. AI bots, lack of digital IDs, and platform bias mean sample isn’t representative. Even balanced arms can hide high‑dimensional heterogeneity. We need to question the data source, not just the treatment.

Follower Power: Does anyone know where I can find regional socio-demographic or economic data for Germany for the early 1990s? Most variables in the INKAR database only start in 1995, so I’m looking for an alternative source.

Yes. But also, Orbán was in power for 14 years until finally a successful challenger emerged and Orbán's popularity drastically declined. So the interesting question to ask is: Why now? And why was Magyar so much more successful in his anti-corruption messaging than others before him?
Hungary’s Orban seemed undefeatable a year ago.
Then Peter Magyar broke through with a powerful anti-corruption platform, rapidly consolidated the fractured opposition, and now leads Fidesz comfortably.
Anti-corruption defeats authoritarianism worldwide. It will work here, too.

Studienzeit - Fadenzeit. Erst gilt das angesichts der historischen Bedeutung des heutigen Tages, denn heute vor genau 53 Jahren fand die erste vorgezogene Bundestagswahl EVER statt. Noch dazu waren erstmals auch 18-, 19- u 20-Jährige dabei. Grund genug für eine Jugendwahlstudie zur BTW25.

Why do some towns seem to win every grant while others can’t get a single project approved?

What drives the uneven geography of development? Or 'why some towns always win'
We show that which places get funding and which miss out depends on whether local governments learn from neighbors, build on past experience, and leverage (or lack) administrative capacity.

Die AfD gibt sich als Partei der kleinen Leute – plant aber gigantische Steuersenkungen für die Reichen. Das oberste Prozent (ab 180k brutto) soll 45 Mrd € weniger zahlen, die Top 10% sogar 86 Mrd € weniger. Kaum Entlastung für Geringverdiener.

A key challenge in interpreting the effects of internal out-migration on voting lies in disentangling compositional from contextual effects (equally applying to our descriptive paper). @moritz-marbach.com great new paper offers empirical guidance on approaching this issue. 👇
