Large-scale industrial and energy-development projects are profoundly affecting the social and economic climate of rural areas across the nation, creating a need for extensive planning information, both to prepare for the effects of such developments and to meet state and federal environmental impact assessment requirements. This book examines alternative methods of modelling the economic, demographic, public service, fiscal, and social impacts of major development projects. The authors provide a synthesis of the conceptual bases, estimation techniques, data requirements, and types of output available, focusing on models that address multiple impact dimensions and produce information at the county and subcounty levels. They also look at the kind of data each model produces in each impact category.
