Core city

Metropolitan areas were no longer considered monocentric, but polycentric due to suburbanization of employment.

[5] Historic core cites in the United States often have higher detached single family housing rates, lower density, and fewer jobs than surrounding satellite cities and suburbs.

[6][7][8] A central city is usually the first settlement established in an urban region, years before the outlying districts came into existence.

[9][10][11][12][13] Central cities often form the regional downtowns of metro areas.

The term is used mainly in US context, although since the 1970s it has also become relatively common in Canada and, to a lesser extent, Europe and Australia.
