Sprawl is how much of the US provides new housing, and so it's interesting to ask the opposite question: Which cities are actually building new housing in walkable neighborhoods? Here is a study published this week by the Terner Center for Housing Innovation at UC Berkeley that looked at exactly this. What they did was divide all US neighborhoods into five categories based on vehicle miles traveled (VMT) per resident in 2023.
The categories:
Very Low VMT - 12 miles per person per day
Low VMT - 17.3 miles per person per day
Mid VMT - 21 miles per person per day
High VMT - 25.5 miles per person per day
Very High VMT - 37.5 miles per person day
These seem like oddly specific distances, but it's what they used to sort new housing supply. Here's all of the US:
Since the 1950s, new home production in very low VMT neighborhoods has generally been declining. Most of the lower VMT stuff was built before the 1940s, which is why New York City is so walkable and its chart looks like this:
Most newer cities do not build in this way. In fact, based on this study, there are only five large metro areas in the US that have (1) built at least 15% of their total housing since 2000 (meaning, they're a younger city) and (2) built at least 40% of their homes over the last decade in lower-VMT neighborhoods (very low and low).
These metro regions are:
This is not that many cities. At the same time, is it even the right benchmark to be aspiring to? "Lower VMT" just means you don't need to drive as much as you might in other neighborhoods. But it doesn't necessarily mean that you live in an amenity-rich and walkable community. What about the new homes being built in neighborhoods where people don't need a car at all? How many of these exist?
Very few, I'm sure.

Urban sprawl is how much of the US provides new housing. And here's Conor Dougherty in the New York Times arguing that America needs more of it to fix its housing shortage:
Even if all the regulatory restraints were removed tomorrow, developers couldn’t find enough land to satisfy America’s housing needs inside established areas. Consequently, much of the nation’s housing growth has moved to states in the South and Southwest, where a surplus of open land and willingness to sprawl has turned the Sun Belt into a kind of national sponge that sops up housing demand from higher-cost cities. The largest metro areas there have about 20 percent of the nation’s population, but over the past five years they have built 42 percent of the nation’s new single-family homes, according to a recent report by Cullum Clark, an economist at the George W. Bush Institute, a research center in Dallas.
The obvious benefit is that the resulting housing tends to be cheap. The above article is filled with examples of people buying large homes for a few hundred thousand dollars in newly formed communities across Texas. And if you live in a high-cost city, the social algorithms have almost certainly found you at some point with a shockingly cheap house in one of these places. But, Dougherty also admits that sometimes this may be the only redeeming quality:
Escobar told me he moved to Princeton because he could find a big house there for less than $300,000, but now the city is home, and he didn’t like where it was headed. Over the next four years, he said, his goal is to redevelop the downtown, try to attract offices where locals can work and build out a park system that voters recently funded with a bond measure. “You ask anybody what they love about Princeton, and it’s simply just the affordability,” Escobar told me. “We need to be more than that.”
According to the article, this isn't necessarily a problem, because it's just how cities are built in this day and age. What you do is start with low-cost housing in fringe locations. You grow as quickly as possible until traffic becomes "godawful" and vital infrastructure can't keep up. Then you implement moratoriums on new housing, and start working on other uses like, you know, employment. Eventually, after all this chaos is complete, you end up with something that possibly resembles a real city.
Yeah, I don't know, this seems like a roundabout way of getting to where you want to go. Why not build and plan for something with a high quality of life right from the start?

Good morning from rainy New Hampshire.
It’s been raining all morning, but apparently there is an ocean hidden in the above picture. We also got in after dark and so all I really saw was what I could see on the drive from the airport.
Whenever I am reminded that the vast majority of built form in North America is car-oriented in nature, I can’t help but think of how sticky all of this is going to be.
Witold Rybczynski put it accurately when he said, “urbanism and architecture observe different time lines.” Buildings may take forever to build, but relative to urban form, they actually change pretty quickly.
New materials and styles emerge, and so do new buildings. But the streets that surround them change so slowly, that for all intents and purposes, they mostly don’t change.
What that means is that, for better or for worse, most of what we see is likely to persist. No wonder there is an arms race going on with autonomous vehicles.
