Take their recent article about increased differentiation between suburban strata as portrayed by the 2010 census, using St Croix county as an example. The paper gets some credit for at least distinguishing between suburbs, noting that nationwide inner suburbs grew at a greater rate than middle suburbs, though not nearly at the rate of outer suburbs. This is an obvious statement. Outer suburbs are starting at smaller populations, so even if a lower number of people move there, it can result in higher percentage growth than larger cities.
