This dataset contains data for food prices on several key food items in the Canadian province of Newfoundland and Labrador collected using citizen science, from October 2020 to December 2021. Data were collected in different places in the province on different timelines, with some locations receiving regular biweekly data and others having a single date inputted. The goal of this dataset was to gain high-resolution temporal data on food pricing to see variations over time, place, stores, online vs in-person shopping, sales, and food items. This data is the basis of the report: Liboiron, Max, Willa Neilsen, Morgan Davidson, Sarah Crocker, Amanda Asiamah, Kaitlyn Hawkins, Brittany Marie Schaefer, Patricia Johnson-Castle, Kerri Claire Neil, Lynn Blackwood, Corinne Neil, Sarah Sauvé, and Charlotte Florian.
