The U.S. Department of Agriculture Economic Research Service (USDA/ERS) maintains four highly related but distinct geographic classification systems to designate areas by the degree to which they are rural. The original urban-rural code scheme was developed by the ERS in the 1970s. Rural America today is very different from the rural America of 1970 described in the first rural classification report. At that time migration to cities and poverty among the people left behind was a central concern. The more rural a residence, the more likely a person was to live in poverty, and this relationship held true regardless of age or race. Since the 1970s the interstate highway system was completed and broadband was developed. Services have become more consolidated into larger centers. Some of the traditional rural industries, farming and mining, have prospered, and there has been rural amenity-based in-migration. Many major structural and economic changes have occurred during this period. These factors have resulted in a quite different rural economy and society since 1970. In April 2015, the Committee on National Statistics convened a workshop to explore the data, estimation, and policy issues for rationalizing the multiple classifications of rural areas currently in use by the Economic Research Service (ERS). Participants aimed to help ERS make decisions regarding the generation of a county rural-urban scale for public use, taking into consideration the changed social and economic environment. This report summarizes the presentations and discussions from the workshop.

How do rural Chinese households deal with the conflicting pressures of migrating into cities to work as well as staying at home to preserve their fields? This is particularly challenging for rice farmers, because paddy fields have to be cultivated continuously to retain their soil quality and value. Drawing on ethnographic fieldwork and written sources, this book describes farming households' strategic solutions to this predicament. It shows how, in light of rural-urban migration and agro-technological change, they manage to sustain both migration and farming. It innovatively conceives rural households as part of a larger farming community of practice that spans both staying and migrating household members and their material world. Focusing on one exemplary resource - paddy fields - it argues that socio-technical resources are key factors in understanding migration flows and migrant-home relations. Overall, this book provides rare insights into the rural side of migration and farmers' knowledge and agency.

This book critically examines different forms of urban-rural links for sustainable development in different countries. As intertwined processes of globalization, digitalization, environmental challenges and the search for sustainable development continue, rural and urban areas around the world become increasingly interconnected and interdependent. This book contributes to understanding the role of this growing interconnectedness from an economic geographical perspective. It does so by theoretically and empirically addressing the various existing linkages, such as food networks, value chains, and regional governance at local, regional, national and international levels. In doing so, contributions extend and contrast existing approaches dealing with urban and rural areas separately by considering the interplay between these two as well as their consequences for sustainability transition pathways. This edited volume adds to the academic and policy debate by bringing together a variety of concepts and themes in order to shift the research and policy agenda away from simple dichotomy to different notions of rural-urban linkages. Offering multidisciplinary insights into rural-urban linkages, the book will be of interest to decision-makers, practitioners and researchers in the fields of economic geography, regional planning, food studies and economics.

First published in 1984. It is widely acknowledged that rural-urban differences and interrelationships play an important role in the development process. Some theorists believe they are a primary cause of continuing poverty in poor nations. This volume of essays summarises and appraises theories of rural-urban relations and economic development and explores, mainly on the basis of country case studies, the conceptual and theoretical problems to which they give rise, and the extent to which they correspond to recent experiences in the Third World.

The thoroughly revised and updated Third Edition of the acclaimed Modern Epidemiology reflects both the conceptual development of this evolving science and the increasingly focal role that epidemiology plays in dealing with public health and medical problems. Coauthored by three leading epidemiologists, with sixteen additional contributors, this Third Edition is the most comprehensive and cohesive text on the principles and methods of epidemiologic research. The book covers a broad range of concepts and methods, such as basic measures of disease frequency and associations, study design, field methods, threats to validity, and assessing precision. It also covers advanced topics in data analysis such as Bayesian analysis, bias analysis, and hierarchical regression. Chapters examine specific areas of research such as disease surveillance, ecologic studies, social epidemiology, infectious disease epidemiology, genetic and molecular epidemiology, nutritional epidemiology, environmental epidemiology, reproductive epidemiology, and clinical epidemiology.

Winner of the Stubbendieck Great Plains Distinguished Book Prize 2019 selection for the One Book One Nebraska and All Iowa state reading programs "Genoways gives the reader a kitchen-table view of the vagaries, complexities, and frustrations of modern farming…Insightful and empathetic." —Milwaukee Journal Sentinel The family farm lies at the heart of our national identity, and yet its future is in peril. Rick Hammond grew up on a farm, and for forty years he has raised cattle and crops on his wife’s fifth-generation homestead in Nebraska, in hopes of passing it on to their four children. But as the handoff nears, their family farm—and their entire way of life—are under siege on many fronts, from shifting trade policies, to encroaching pipelines, to climate change. Following the Hammonds from harvest to harvest, Ted Genoways explores the rapidly changing world of small, traditional farming operations. He creates a vivid, nuanced portrait of a radical new landscape and one family’s fight to preserve their legacy and the life they love.
