As Emily Badger reports, "the Urban Institute recently created a helpful new mapping tool that tracks fine-grained Census data on poverty for every metropolitan area of the country, spanning the years from 1980-2010. The patterns vary by city (Chicago Magazine has a good discussion of what the tool illustrates there). Just about everywhere, however, poverty appears to be spreading."
"In some cities, like Milwaukee, it remains racially segregated, with the black poor living in one part of town, the white poor in another, and the Hispanic and Asian poor in separate pockets. In other cities, like Houston, racially diverse families living under the poverty line appear to share some of the same neighborhoods."
