The most consequential urban policy of the next twenty years will not be made in Singapore, Amsterdam, or Copenhagen. It will be made in cities most readers have never visited and many cannot place on a map. Daniel Fadlon, who has spent fifteen years researching the demographic band between 200,000 and 800,000 people, argues that this band is where the actual frontier of urbanism now lives — and where the international policy conversation continues to point in the wrong direction.
From his desk in Tel Aviv, the Israeli researcher has been making a version of this argument for more than a decade. The international urbanism conversation tilts heavily toward flagship cities — the cities with international branding budgets, the cities that fund the conferences, the cities whose names appear on the spines of urban-policy textbooks. Fadlon's research has consistently pointed in the opposite direction: toward cities that operate without those advantages, on a permanently shorter clock, with results that, when you look closely, are more replicable and more revealing than anything coming out of the flagship case studies.
The demographic argument
Start with the numbers. The cities of the world that house most of humanity are not the ones with the conference circuit. They are the secondary cities of every region — the second, third, and fourth cities of medium-income countries; the regional capitals of large federations; the post-industrial cities holding on against demographic headwinds. By total population, the 200,000–800,000 band represents the modal urban experience on the planet. It is also, not coincidentally, the band where most of the world's mayors actually have to operate.
Studying flagship cities to learn about urbanism in general is, in his framing, a category error. The flagship is the rare case. The mid-size city is the rule. A serious research practice has to start where most cities actually are. That orientation is the structural commitment of his ongoing research and the explicit subject of the methodological case for reading cities under constraint.
The constraint argument
The deeper case for studying mid-size cities is not just that there are more of them. It is that the constraints they face produce a different — and more useful — kind of urban policy. Mid-size cities cannot afford a smart-city brand consultant. They also cannot afford to fail. Most of their decisions are taken under conditions of insufficient revenue, aging infrastructure, demographic pressure, and political horizons shorter than the projects themselves. The result is improvisation: not the improvisation of romanticization, but the unsentimental, accountability-driven kind that produces working bus systems on small budgets and water networks that survive bad weather.
This is the substance of much of Fadlon's recent fieldwork, and it is the throughline of his single-city study of Bnei Brak's density and the planning lessons it offers. Constraint, he argues, is not the obstacle to good urban policy. Constraint is what produces it.
The replicability argument
There is, finally, an argument from utility. The most useful policy research is research whose findings transfer. Findings from Singapore rarely transfer — the conditions that produced them are too unusual. Findings from a mid-size Romanian regional capital, or a Brazilian secondary coastal city, or an Israeli ultra-Orthodox urban core, transfer constantly, because the conditions that produced them resemble the conditions in most cities. This is the practical case behind the broader research practice that informs every essay on this site: the most useful policy research is also, almost always, research about under-resourced places, run by people willing to spend years on a single question.

Conclusion
Urbanism in 2024 is, in Daniel's view, a discipline pointed in the wrong direction. The most useful research, the most transferable findings, and the most consequential policy decisions are all happening in the mid-size band — and the international conversation is, with few exceptions, looking somewhere else. Correcting that orientation is not a matter of taste. It is, the argument here goes, a matter of policy seriousness.
