There is something special about living on an island, particularly one where the population density is kept under control. That's also the case in Scotland where a new study has shown that islanders have the best quality of life. Orkney, Shetland and the Outer Hebrides came in the top three respectively in a Bank of Scotland survey. A number of factors contributed to the result including including health, low pollution levels, employment, low crime rates, nature and wildlife, low population density and the beauty of the location.
