Actually Stoughton isn't an "Urban" area it's a middle to upper middle class (even aruably affluent) suburb South of Boston.
It's actually a growing community with an influx of Portuguese and Cape Verdean immigrants who are joining Urban transplants who've moved into the area.
It's also about 25 miles from where the the Evangelical Congregation is located.
On the face of it, it appears that the Evangelical Congregation is about to abandon an Urban area for the greener pastures of an affluent suburb.
Spot-on!
