That may be true in some cities but not so much in London, Bear in mind too
that children are particularly affected by pollution, and many primary schools
and routes to school in the inner city are on or near main roads.

This report matched social deprivation with air pollution, finding a
correlation in London but not Glasgow:

"The increase in deprivation with increasing air pollution is clearer for
London and Belfast. For Glasgow the opposite pattern is evident, with a
slight decrease in air concentration with increasing deprivation. This is
likely to be owing to a different geography of deprivation in Glasgow compared
with the other cities, possibly because of large peripheral housing estates
built as part of city centre slum clearance schemes."

By and large, poorer people do tend to suffer from factors that affect their
health more -regarding roads, accidents certainly so.
