Three-year estimates ending in 2012 and 2009 from the U.S. Census Bureau's American Community Survey, mapped by neighborhood -- technically Public Use Microdata Areas, or PUMAs. A few PUMAs changed shape slightly between surveys, which could have a minor effect on our calculation of the change in those areas. All figures adjusted to 2012 dollars, and all ACS survey data is subject to margins of error, which are indicated on the map.
