Editorial: Recent Advances in Survey Methods for Collecting Food Data

High-quality food data collected from consumption and expenditure surveys are essential for researchers and policy makers to better understand trends in social, economic, and human development. Over the last decade, food surveys have faced various challenges to sustain high data quality, such as declining response rates and increasing respondent burden. At the same time, new opportunities around the use of new technologies and alternative data sources have emerged that can potentially address some of these challenges. This special issue, inspired by the International Food Acquisition Research and Methods (iFARM) Workshop held at the University of Maryland, College Park, in October 2022, presents recent methodological advancements in the collection of food survey data. The four papers contained in this issue contribute to research about increasing and sustaining data quality in such surveys. They compare traditional paper- and web-based approaches vis-à-vis novel smartphone-based approaches for collecting food data, explore the measurement of food preparation and consumption through time-use diaries, and examine the feasibility of innovative technologies to reduce respondent burden in food surveys.
