Data analysis reveals that US cities are segregating the wealthy | Ars Technica

Essentially, the more cities require independent reviews and community meetings to develop land, the more income-segregated the city becomes. Density restrictions also cause wealthy enclaves, regardless of whether they mandate minimum or maximum density in an area. Even if your city mandates high density housing (or creates special zones for low-density, single-family homes), it won’t necessarily solve the problem of income segregated neighborhoods. Finally, in an interesting twist, it turns out that the more local government and citizens groups control development, the more segregated its wealthiest members become.
