Ed Glaeser and Jacob Vigdor report on the data from the 2010 census:
- 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.
