Counties of Denmark in the context of "Aabenraa County"

South Jutland County (Danish: Sønderjyllands Amt) is a former county (Danish: amt) on the south-central portion of the Jutland Peninsula in southern Denmark.

The county was formed on 1 April 1970, comprising the former counties of Aabenraa (E), Haderslev (N), Sønderborg (SE), and Tønder (SW). The county was abolished effective 1 January 2007, when the Region of Southern Denmark was formed.

The Region of Southern Denmark (Danish: Region Syddanmark, pronounced [ʁekiˈoˀn ˈsyðˌtænmɑk]; German: Region Süddänemark, pronounced [ʁeˈɡi̯oːn zyːtˈdɛːnəˌmaʁk]; North Frisian: Regiuun Syddanmark) is an administrative region of Denmark established on Monday 1 January 2007 as part of the 2007 Danish Municipal Reform, which abolished the traditional counties ("amter") and set up five larger regions. At the same time, smaller municipalities were merged into larger units, cutting the number of municipalities from 270 (271 before 2006) before 1 January 2007 to 98. The reform diminished the power of the regional level dramatically in favor of the local level and the central government in Copenhagen. The Region of Southern Denmark has 22 municipalities. The reform was implemented in Denmark on 1 January 2007, although the merger of the Funish municipalities of Ærøskøbing and Marstal, being a part of the reform, was given the go-ahead to be implemented on Sunday 1 January 2006, one year before the main reform. It borders Schleswig-Holstein (Germany) to the south and Central Denmark Region to the north and is connected to Region Zealand via the Great Belt Fixed Link.

The regional capital is Vejle but Odense is the region's largest city and home to the main campus of the University of Southern Denmark with branch campuses in Esbjerg, Kolding and Sønderborg.The responsibilities of the regional administration include hospitals and regional public transport, which is divided between two operators, Sydtrafik on the mainland and Als, and Fynbus on Funen and adjacent islands. On the island municipalities of Ærø (since 2016) and Fanø (since 2018), the municipalities themselves are responsible for public transport. Billund Airport is region's main airport, it is the second-busiest airport in Denmark behind Copenhagen Airport and one of the busiest air cargo centres. It handes an average of more than three million passengers a year, and millions of pounds of cargo.

Haderslev County (Danish: Haderslev Amt) is a former province in Denmark, located on the northernmost part of Southern Jutland. Haderslev County was established in 1920 following the reunification of Denmark and South Jutland following the Schleswig Plebiscites. It was dissolved in 1970 when it merged with three other counties to form South Jutland County. Haderslev County corresponded geographically to the former Prussian Kreis Hadersleben except for Hvidding Herred which was transferred to Tønder County. Half of Tyrstrup Herred was transferred from Haderslev County to Vejle County when Denmark surrendered Schleswig to Prussia and the Austrian Empire in 1864, and this region remained Danish.

Sønderborg County (Danish: Sønderborg Amt) is a former province in Denmark, located on the island of Als and the easternmost part of Southern Jutland. As of 2017 its population was 27,000.

Tønder County (Danish: Tønder Amt) is a former province in Denmark, located the south-western part of Southern Jutland. Tønder County was established in 1920 following the reunification of Denmark with South Jutland following the Schleswig Plebiscites. It was dissolved in 1970 when the bulk of the county merged with three other counties to form South Jutland County. Tønder County corresponded geographically to the northern part of the former Prussian Kreis Tondern except for Hviding Herred, which had been part of Kreis Hadersleben. Kreis Tondern had in turn been established in 1867 in order to simplify the intricate administrative structures of the Duchy of Schleswig, and was formed from regions belonging to Ribe County (exclaves of Denmark) and Løgumkloster County (parts of Schleswig).

The southern part of Kreis Tondern remained German and became Kreis Südtondern, with the seat transferred to Niebüll. In 1970, Kreis Südtondern merged into Kreis Nordfriesland.

The five regions of Denmark (Danish: regioner) were created as administrative entities at a level above the municipalities and below the central government in the public sector as part of the 2007 Danish Municipal Reform, when the 13 counties (amter) were abolished. At the same time, the number of municipalities (kommuner) was cut from 270 (from 271 in 2006) to 98. The reform was approved and made into a law by the lawmakers in the Folketing 26 June 2005 with elections to the 98 municipalities and 5 regions being held Tuesday 15 November 2005.

Each of the five regions is governed by a popularly elected regional council with 41 members, from whom the regional chairperson is chosen. This is 205 members in total. The number of regions will be reduced to four from 1 January 2027. The number of council members elected will change to between 25 and 47 in the 2025 Danish local elections for a total of 134 in the four regional councils that will then be elected.

The Central Denmark Region (Danish: Region Midtjylland), or more directly translated as the Central Jutland Region and sometimes simply Mid-Jutland, is an administrative region of Denmark established on 1 January 2007 as part of the 2007 Danish municipal reform. The reform abolished the traditional counties (amter) and replaced them with five new administrative regions. At the same time, smaller municipalities were merged into larger units, cutting the total number of municipalities from 271 to 98. The reform diminished the power of the regional level dramatically in favour of the local level and the national government in Copenhagen. The Central Denmark Region comprises 19 municipalities.
