This book brings together a series of articles which provide an overview of the Irish Diaspora from a global perspective. It combines a series of survey articles on the major destinations of the Diaspora; the USA, Britian and the British Empire. On each of these, there is a number of more specialist articles by historians, demographers, economists, sociologists and geographers. The inter-disciplinary approach of the book, with a strong historical and modern focus, provides the first comprehensive survey of the topic.
