The data for the analysis comes from shopping lists in Listonic and Moja Gazetka. The study has been supplemented with data from Moja Gazetka since October 2024.From June 2026 the method of counting additions has been refined: re-marking a product as to buy after it was previously checked off as bought (an "uncheck") now also counts as an addition to the list. This change affects data from June 2026 onwards – worth bearing in mind when comparing with earlier periods.
