Anotations

Scope note:

Areas of cities or towns that are residential or more prosperous areas, but still remaining within the central urban boundaries, not the suburbs. The term is thought to derive from these areas, in historic times, having been laid out radiating away from the older business center, thus having higher street numbers than the older areas; alternatively, the term may derive from the development of New York City, where the historical newer residential sections were in the north of Manhattan Island, at the top of a map.
