Endelave, Tunø, Hjarnø and Alrø in Kattegat, as well as Venø, Jegindø and Fur in the Limfjord. The western parts of the region are characterised by coastal dunes and inland heaths, while the slightly elevated central parts and the relatively hilly eastern parts are characterised by forests, lakes and streams, with plenty of fertile soils. The eastern parts (Østjylland) are the most densely populated area within the region and form a large part of the proposed East Jutland metropolitan area with a population of about 1.4 million. Aarhus, with a population of 280,000, is the largest city of Jutland and the second-largest city of Denmark, as well as the hub of Eastern Jutland. Other cities with a population above 30,000 include Randers, Silkeborg, Horsens, Herning, Viborg and Holstebro. Most of these are situated in the eastern part. The administration and regional council is situated in the sixth-largest city, Viborg, which has a population of 40,000 and was the medieval capital of Jutland. Administratively, Central Denmark Region consists of the former counties of Ringkjøbing and Aarhus (except the western half of Mariager municipality which joined Region Nordjylland), most of the former county of Viborg, and the northern half of Vejle County. The areas in question from the two latter counties were the former municipalities of Bjerringbro, Fjends, Hvorslev, Karup, Kjellerup, Møldrup, Sallingsund, Skive, Spøttrup, Sundsøre, Tjele and Viborg from Viborg County and Brædstrup, Gedved, Hedensted, Horsens, Juelsminde, Nørre-Snede and Tørring-Uldum from Vejle County. The neighbouring administrative region to the south is the Region of Southern Denmark (), as it includes not only the southern parts of Jutland, but also the island of Funen and smaller neighbouring islands. Furthermore, Sønderjylland (Southern-Jutland) is the traditional name for North Slesvig, which is the Danish part of the former Duchy of Schleswig/Slesvig. Geologically, the region lies in the northern part of Denmark, which is rising because of post-glacial rebound. For statistical purposes, the region has two divisions or provinces: East Jutland and West Jutland. These are almost, but not entirely, identical with the parliamentary constituencies of East Jutland and West Jutland. The western constituency is much larger in area, but has a smaller population than the eastern one. Significant local antagonism arose before the region came into effect in 2007 and in the first years of its existence. Citizens in the northwestern areas protested against the closure of the hospital of Holstebro. In the 2009
