This book traces the development of community development/organization as it evolved separately in Britain and the United States, and how the social and political situations in each country determined the various shapes and directions it took. In presenting a comprehensive history of the subject, _Community Organization and Development_ draws on local and international factors that have helped to shape its application and fortunes across varied settings. Recent economic and social pressures, the changing demographics of developed economies, and the rise of social and cultural diversity all contribute to the need for a comprehensive model that can be deployed to effect the necessary social changes required for sustained change with stability. The history of this intervention technique throws up many examples from which insight can be gained for the present time, and Wales is used as an example of how national policy and local development could be combined for maximum effect. Community development should become reliable and quantifiable, and the comprehensive model developed here demonstrates how and when it should be deployed.
