Orkney
Orkney is an archipelago in the Northern Isles of Scotland. It is positioned 10 miles north of the coast of Caithness and contains 70 islands, of which 20 have settlements. The island chain has a total area of 523 square miles, meaning that it is the sixth largest Scottish island and the tenth largest island in the UK. Kirkwall is Orkney's most substantial administrative centre. Orkney makes up one of the 32 council regions of Scotland, as well as being a constituency of the Scottish Parliament, a lieutenancy region and a former county. The regional council is Orkney Islands Council, being one out of 3 councils in Scotland that have a majority of elected members who are independents. The majority of the islands are divided into 2 groups, the North and South Isles, and a characteristic of all the islands is the existence of Old Red Sandstone. With a mild climate and significantly fertile soil, farming continues to be the most significant area of the economy. Exportation of beef, cheese, whisky, beer and fish also continues to have a part in the economy, but there has actually been an increase in areas including retail, accounting for 17 percent of overall employment. Increasing in importance are the wind and marine energy sources, and the island produces in excess of its yearly electrical power requirement through these techniques. In accordance with the 2011 census, Orkney has a population of 20100, growing 11 percent from the 2001 census. Multiple events occur on the islands which attract large numbers of locals and citizens, for example the Orkney International Science Festival and the St. Magnus International Arts Festival happening every year in June.
