Every year millions of digital records containing personally identifiable information are exposed. When are malicious hackers to blame, and when is it organizational malfeasance? Which kinds of organizations—private firms, government agencies, or educational institutions—loose the most data? With over 1.9 billion records lost (on average that's 9 records per U.S. adult), a surprising number of the breaches can be attributed to organizational practices.

This review focuses on recent methodological and technological developments in survey data collection. Surveys are facing unprecedented challenges from both societal and technological changes. Against this backdrop, I review the survey profession's response to these challenges and developments to enhance and extend the survey tool. I discuss the decline in random digit dialing and the rise of address-based sampling, along with the corresponding shift from telephone surveys to self-administered (mail and/or Web) modes. I discuss the rise in nonprobability sampling approaches, especially those associated with online data collection. I also review so-called big data alternatives to surveys. Finally, I discuss a number of recent methodological and technological trends designed to modernize the survey method. I conclude that although they face a number of major challenges, surveys remain a robust and flexible method for collecting data on, and making inference to, populations.

Statistical surveys represent an important source of scientific knowledge and a valid decision support tool in many fields, from social studies to economics, market research, health studies, and others. Scientists have tackled most of the methodological issues concerning surveys and the scientific literature offers excellent proposals for planning and conducting surveys. Nevertheless, surveys often require the achievement of aims that either deviate from the methodology or do not have a specific solution at all. This book focuses on survey theory and applications, providing insight and innovative solutions to face problems in data collection and integration, complex sample design, opinion questionnaire design, and statistical estimation. Formal rigour and simple language, together with real-life examples, will make the book suitable to both practitioners involved in applied research and to academics interested in scientific developments in the survey field.
