The Atlantic has an interesting look at the Boston area, mapping the city by the dominant class (creative, service, or working) in each census tract:

The map pictured at the top of the article doesn't include Somerville, but the interactive map further down does. The tracts around Davis, for instance, are around 60-70% creative class, with between 1% and 6% working class.
