area by definition includes the Haspolat region which is also considered to be a part of the city proper as it is within the Nicosia Turkish Municipality jurisdiction, the municipality of Alayköy and the village of Kanlıköy under the jurisdiction of Gönyeli, where North Nicosia is projected to grow. The metropolitan area has an area of 165.2 square kilometres. The quarters of Nicosia outside the walled city are more spacious than the walled city, with wider roads and junctions. These areas are characterized by multi-floor concrete buildings. In the outskirts of the city, a number large and imposing villas have been built that belong to the middle and upper-classes.

Turkish Cypriots follow a more secularized lifestyle than the more conservative settlers, leading to tension between the communities. However, in the 2010s, a significant number of settled workers in the walled city left Northern Cyprus. Historically, Turkish Cypriots had concentrated to the north of the riverbed and Greek Cypriots to the south. The Green Line was drawn to separate the Turkish quarters of the city from the Greek quarters, and 7000 Turkish Cypriots, around 30% of the Turkish population of Greater Nicosia, were displaced from quarters of the walled city and some suburbs such as Küçük Kaymaklı/Omorphita. North Nicosia also received a great number of displaced Turkish Cypriots from surrounding villages. The Göçmenköy quarter (literally meaning "village of the displaced") was founded to resettle these displaced people. The Arab Ahmet quarter had had an Armenian Cypriot presence since the Ottoman conquest; having been a
