Ed Glaeser and Jake Vigdor find that all-white neighborhoods are a thing of the past. They find:
- The most standard segregation measure shows that american cities are now more integrated than they’ve been since 1910. Segregation rose dramatically with black migration to cities in the mid-twentieth century. On average, this rise has been entirely erased by integration since the 1960s.
- All-white neighborhoods are effectively extinct. A half-century ago, one-fifth of America’s urban neighborhoods had exactly zero black residents. Today, African-American residents can be found in 199 out of every 200 neighborhoods nationwide. The remaining neighborhoods are mostly in remote rural areas or in cities with very little black population.
- Gentrification and immigration have made a dent in segregation. While these phenomena are clearly important in some areas, the rise of black suburbanization explains much more of the decline in segregation.
- Ghetto neighborhoods persist, but most are in decline. For every diversifying ghetto neighborhood, many more house a dwindling population of black residents.
That said, Andy Reschovsky sends me to the most recent US Census Homeownership and Vacancy Report, which shows the ration of black to white ownership rates fell from .643 in 2006 to .617 in 2011; for hispanics, the fall was from .651 to .632.
