Single family cities?

The NY Times has a new richly-illustrated piece from Emily Badger and Quoctrung Bui that asks how our cities can live without density. The heart of the analysis is a series of 10 maps showing how major American cities are divided between single family homes and all other forms of housing. Of the cities they mapped, only DC and NYC have less than 50% single family units. The article is expansive and includes intriguing quotes from multiple faculty who raise fundamental questions about zoning as a tool.

And, they get through the entire piece without ever using the phrase, "Not in my backyard".
