The island has been occupied since the mesolithic period and has a colourful history. It was rule by the Norse for 400 years, then dominated by Clan MacLeod and Clan Donald. The Highland Clearances of the 19th century caused a decline in the population from over 20,000 to around 9,200 in the early 21st century. The population has risen 4% from the census of 1991. The main industries are tourism, agriculture, fishing and whisky-distilling.
