This is a chart from Abundant Housing LA (a YIMBY group), via City Observatory, showing the relationship between median household income and single-family zoning across the 88 cities that make up L.A. County. On average, about 80% of the land in the County is zoned for single-family housing. This is also true for Los Angeles, which is not surprisingly its biggest city. What is pretty clear from this chart is that the richest areas tend to have a higher percentage of single-family homes. If you read Anthony Dedousis' post, you'll also see that the housing tends to be more expensive (makes sense) and that the homeownership rates are higher in these single-family areas. One obvious takeaway is that it shows you how clearly we are dividing our cities. Zoning is regulation. And here we are seeing some of the socioeconomic implications. But I'm curious if this relationship would be as strong in other cities around the world and at different scales (i.e. neighborhood levels). When it's made available (not all cities have this much space), how universal is this pull toward single-family housing?
