This document discusses the future of traditional survey research methods. It notes that telephone response rates have declined significantly in recent years as cell phone-only households have risen. Online and mobile methods are increasing but have challenges representing the population. Probability-based online panels can help address this but modeling approaches to make non-probability panels representative have had mixed results. The document argues that no single method will replace traditional surveys due to increasing fragmentation across devices and data sources, but various approaches may be useful depending on the specific research question.
