Netherlands and forms the centre of the Greater The Hague urban area. Westland and Wateringen lie to the south, Rijswijk, Delft and the Rotterdam conurbation (known as Rijnmond) to the southeast, Pijnacker-Nootdorp and Zoetermeer to the east, Leidschendam-Voorburg, Voorschoten and the Leiden conurbation to the northeast and Wassenaar to the north. The conurbations around The Hague and Rotterdam are close enough to be a single conurbation in some contexts. For example, they share the Rotterdam The Hague Airport and a light rail system called RandstadRail. This led to the creation of the Rotterdam-The Hague metropolitan area. This large conurbation centred on The Hague and Rotterdam is, in turn, part of the Randstad—specifically a band of municipalities called the South Wing (Zuidvleugel). The Randstad, which also includes among others Amsterdam and Utrecht, has a population of 6,659,300. The Hague lies at the southwestern corner of the second-largest conurbation in the European Union. The Hague is divided into eight official districts which are, in turn, divided into neighbourhoods. Some of the most prosperous and some of the poorest neighbourhoods of the Netherlands can be found in The Hague. The wealthier areas like Statenkwartier, Belgisch Park, Marlot, Benoordenhout and Archipelbuurt are generally in the northwestern part of the city, closer to the sea, whereas the southeastern neighbourhoods like Transvaal, Moerwijk, and the Schilderswijk are significantly poorer, with the exception of the Vinex-locations of Leidschenveen-Ypenburg and Wateringse Veld. This division is reflected in the local accent: The more affluent citizens are usually called "Hagenaars" and speak so-called bekakt Haags ("posh"), this contrasts with the Hagenezen, who speak plat Haags ("vulgar"); see Demographics below. The districts are: Centrum (106,000 inhabitants) forms the heart of The Hague. The Binnenhof, the Noordeinde Palace, the Mauritshuis museum, the Nieuwe Kerk, the Grote Kerk, the Old City Hall and the City Hall are located here. Architecture varies from medieval up to 20th century. Escamp (129,000 inhabitants) is the most populous district of The Hague, built largely after the World War II as part of The Hague's large expansion to the south east. One railway station can be found here: Den Haag Moerwijk. The district is divided into six neighbourhoods. Haagse Hout (48,000 inhabitants) is a wealthy district in the northeast of the city and the location of the Haagse Bos, a large forest. The King of the Netherlands lives in the royal palace Huis ten Bosch, in this forest.
