In the metro area I grew up in, Dayton, the southern suburbs were much nicer than the northern ones. The nicest small suburb is Oakwood, due south of the city of Dayton, and the nicest of the large inner suburbs is Kettering, also due south.

I agree with the article that North sounds more upscale.

In the US, France, Spain, Mexico, and Italy the north is wealthier. In England, Brazil, China, and Germany, the south is wealthier.
