Non-probability Survey Samples

Abstract

We provide an overview of the emerging topic of non-probability survey samples which has drawn increased attention in the fields of survey methodology and official statistics. We highlight some of the issues in analyzing non-probability survey samples and present some of the methodological advances that have appeared in recent years. One important message from this chapter is that probability survey samples and design-based inference, which are the main focus of most other chapters of the book, play a fundamental role in the theoretical framework for non-probability survey samples.
