New Orleans used to be 67 percent black and only a quarter white. Now white people make up 30 percent of the city, while the black population doesn’t seem to be returning at the same rate, accounting for just 60 percent of the population, according to the 2010 Census. That change—67 percent to 60 percent—might seem like a modest one, but when you crunch the numbers the human toll is clear: by 2010, the city’s white population had just about returned to its pre-Katrina levels, while today approximately 100,000 black people are still missing from New Orleans.
