Three centres of population exist: the long-established town/village of Costessey (now commonly Old Costessey) (2011 population 7,265); New Costessey of similar population, incepted in the first half of the 20th century, a long network of generally residential roads north of Dereham Road, contiguous with three smaller western suburbs of the county town (city); and Queens Hill which is green-buffered and which has a small country park, mature woodland and a large golf course adjoining. The parts named Old and New are separated by the Tud, adjoining fields and by a retail/business park in the west, a divide of about 2 miles (3.2 km). Old Costessey's northern limit is with Taverham, D
