The global urbanisation story is mostly a story of failure. Megacities in the developing world have grown faster than their infrastructure. Housing costs in wealthy cities have spiralled beyond the reach of the middle class. Traffic congestion, air pollution, and spatial inequality have worsened in most places urbanisation has accelerated.
But not everywhere. A handful of cities — and the countries that planned for them — managed the transition differently. Understanding what they did is increasingly urgent, as another 2.5 billion people are projected to move to cities by 2050.
Singapore: Density Done Right
Singapore is the most obvious example, though also the most frequently misunderstood. It is often cited for its efficiency, its cleanliness, its authoritarian neatness. What deserves more attention is its housing model. Over 80% of Singaporeans live in flats built and sold by the government’s Housing Development Board at subsidised prices. The programme was ambitious, politically difficult, and executed over decades. The result is a city-state where housing costs, while rising, have not priced out the middle class in the way they have in London, Sydney, or San Francisco.
Japan: Building Supply
Tokyo is the world’s largest city by population — and one of its most affordable major cities by price-to-income ratio. The explanation is largely supply. Japan, unlike most wealthy countries, has consistently permitted dense residential construction in desirable urban areas. Zoning rules are set nationally rather than locally, limiting the ability of incumbent homeowners to block new development in their neighbourhoods.
The result is that Tokyo adds roughly 140,000 new homes per year. London, with a comparable population, adds fewer than 40,000. The difference in housing costs reflects this gap in supply.
The Common Thread
What Singapore and Japan share is not a specific policy tool, but a political willingness to override the short-term interests of existing property owners in favour of the long-term interests of future residents. This is rare everywhere, because future residents don’t vote in current elections and existing homeowners do. The countries that got urbanisation right found ways — whether through technocratic insulation, national rather than local planning powers, or simply political courage — to make decisions that served the many rather than the few who already had homes to protect.
