Clearly there are lots of unique challenges of suburbia that are not seen anywhere else. Fast pace of life, affluence, long commutes, little sense of community to name just four. But the one Ros raised was to what extent the suburban environment is intrinsically middle-class. After all it is full of people who work in the city but are wealthy enough to live out of the inner city. Many who move here do so for aspirational reasons, thinking it provides a nice family environment, good schooling, all the benefits of the city with none of the social challenges of more deprived areas. it would be interesting to read some social geography analysis on the class make-up of suburbia. My guess is that Ros is right - it is overwhelmingly middle-class.
