This book provides a detailed, student-friendly overview of Ireland in the twenty first century and the remarkable economic and social transformations that have occurred since the late 1980s. The "Celtic Tiger" phenomenon has made Ireland the focus of much attention in recent years. Other countries have openly declared that they want to follow the Irish economic and social model. Yet there is no book that gives a comprehensive, spatially-informed analysis of the Irish experience. This book fills that gap. Divided into four parts -- planning and development, the economy, the political landscape, and population and social issues -- the chapters provide an explanation of a particular aspect of Ireland and Irish life accompanied by illustrative material. In particular, the authors reveal how the transformations that have occurred are uneven and unequal in their effects across the country and highlight the challenges now facing Irish society and policy-makers. Written by experts in the field, it is a key text for those wishing to understand the contemporary Irish economic and social landscape.
