According to this recent report by Smart Growth America, which looked at “walkable urbanism” in the largest 35 metro areas in the US, only about 1.2% of land is, on average, built out in this way. Everything else needs to be driven. But here’s the… Read More
There’s lots of data out there to suggest that there is a correlation between urban density and housing unaffordability. Take Hong Kong. It is very dense, and also one of the most expensive housing markets in the world. But I think the real question is:… Read More
This data is from 2019, but I imagine that things would look pretty similar today and that it might even be a little more pronounced. The dataset from the above article looked at how many people have cars in a given area (a darker dot… Read More
When it comes to greenhouse gas emissions, we know this: Households in denser neighborhoods close to city centers tend to be responsible for fewer planet-warming greenhouse gases, on average, than households in the rest of the country.

This is a great diagram from Smart Density comparing the urban and regional rail networks of Toronto, London, and Paris. All are at the same scale. What immediately stands out to me — besides Toronto’s relatively miniscule network — is Paris’ compactness. I have said… Read More
The typical way to measure carbon emissions is to think about it in terms of geography. You pick a particular place, such as a country or a city. You add up all the emissions that are taking place within its boundaries. And you’re then left… Read More

Gas prices are up. And here is a chart to support this statement: If I were trying to be as sensational as possible, I would likely leave things here. But since that is generally not what I try and do with this blog, here is… Read More
The UN’s Intergovernmental Panel on Climate Change (IPCC) has just published its latest climate change report. Available here. As a follow-up to this report, Dezeen spoke with Hélène Chartier of the sustainable urbanism network C40 Cities. And she makes some very good points about the… Read More
The relationship between car ownership and urban density is a fairly intuitive one. Below are two charts from a study by Francis Ostermeijer, Hans Koster, Jos van Ommeren, and Victor Nielsen, showing how urban density is inversely correlated with car ownership. In other words, the… Read More
