Our OUP Handbook on Polling and Survey Methods has brought together a unique mixture of academics and practitioners, from various backgrounds, academic disciplines, and experiences. In some sense, this is reflective of the interdisciplinary nature of the polling and survey industry: polls and surveys are widely used in academia, government, and the private sector. Designing, implementing, and analyzing high quality, accurate, and cost-effective polls and surveys requires a combination of skills and methodological perspectives. Despite the well-publicized issues that have cropped up in recent political polling, a great deal is known today about how to collect high quality polling and survey data even in complex and difficult environments. We hope that the chapters in this Handbook help researchers and practitioners understand these trends, and to participate in the development of new and better approaches for measuring, modeling, and visualizing public opinion and social behavior.
