Poor densely populated city area (6)

Ross

I believe the answer is:

ghetto

(Other definitions for ghetto that I've seen before include "Slum part of city occupied by minority group" , "Densely populated slum area" , "poor part of town" , "A poor quarter of a city" , "Restricted quarter" .)

I've seen this clue in The Guardian.
