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
I rediscovered the maps and work of Alasdair Rae this morning. (He has appeared on this blog before in posts like this one here.) Alasdair works in the Department of Urban Studies and Planning at the University of Sheffield and is author of the blog,… Read More
Urban environments can be dense in many different ways. This is a topic that we have discussed on several occasions here on the blog. But this working paper by Solly Angel, Patrick Lamson-Hall, and Zeltia Gonzales Blanco — called The Anatomy of Density — is… Read More
There is something happening in many North American cities right now. We are starting to question the supremacy of zoning for only single-family homes. This past summer, the state of Oregon passed policy requiring cities of 25,000 people or more to allow duplexes, triplexes, and… Read More

The New York Times has a recent article up talking about the disappearing “urban advantage” for low-skilled workers. It is based on the work of MIT economist David Autor. Here is a chart from the article plotting wages against population density from 1950 to 2015: The… Read More
This is an interesting working paper by a team of researchers at NYU’s Marron Institute of Urban Management. The paper examines the relationship between urban density and organized violence, first in Colombia and then within a sample of 200 global cities. The finding is that… Read More
Today I came across this Reddit talking about how few census tracts there are in the United States with a population density greater than 150,000 people per square mile. Basically, there’s a bunch in New York, one in San Francisco (Tenderloin), and one in Chicago… Read More
