Islands have always fascinated people. They often seem remote and mysterious, set between the continents on which most people live. Indeed, many people choose islands for their perfect holiday idyll. In practice, however, the everyday social and economic reality is often very different. This work firstly examines the differing ways islands are formed. Despite the uniqueness of such islands in terms of shape, size, flora and fauna, and also their economic and developmental profiles, they all share certain characteristics and constraints imposed by their insularity. These present islands everywhere with a range of common problems. The author considers how their small scale, isolation, peripherality and often a lack of resources, has affected islands, in the present day and their past. It considers and discusses population issues, communications and services, island politics and new ways of making a living, especially tourism, found within contemporary island geography.
