Central Denmark Region (Danish: Region Midtjylland) is an administrative region of Denmark established on 1 January 2007 as part of the 2007 Danish Municipal Reform, which replaced the traditional counties ("amter") with five larger regions. At the same time, smaller municipalities were merged into larger units, cutting the number of municipalities from 271 before 1 January 2006, when Ærø Municipality was created, to 98. The reform was implemented in Denmark on 1 January 2007.
^Danish state authorities use both the Danish name Midtjylland and the direct translation Central Jutland in English texts. Central Jutland Region or Region of Central Jutland are also widely used by others (e.g. the city of Århus), but the Region itself prefers 'Central Denmark'.
