Conurbations
Rotterdam is in the south of the Randstad. Having a population of 7.1 million, the Randstad is the sixth-largest metropolitan area in Europe (after Moscow, London, the Ruhr Area, Istanbul, and Paris).
The southern part of the Randstad (i.e. the part located in the Province of South Holland) is called the "South Wing" (Zuidvleugel). Including Leiden, The Hague, Zoetermeer, Delft, Vlaardingen, Schiedam, Capelle aan den IJssel, Spijkenisse and Dordrecht, the Zuidvleugel has a population of around 3 million.
At the heart of the Zuidvleugel are the conurbations surrounding The Hague and Rotterdam. They are close enough to be almost a single conurbation with a population of about 2.5 million. They share the Rotterdam The Hague Airport and a light rail system called RandstadRail. Consideration is being given to creating a Rotterdam-The Hague metropolitan area (metropoolregio).
