Design/methodology/approach – The paper extends the literature through the combination of a novel approach and unique dataset of US consumers, and addresses the relationship between demographic traits and the likelihood of buying organic food. The dataset consists of primary data recording all purchases of food as well as household demographic data, such as income, education, gender, and ethnicity, over a one-year period for 44,000 households. The study uses different discrete choice models and multiple product categories to explore the likelihood of buying organic food from many angles, in order to assess the robustness of the statistical relationship between income, education, ethnicity, and other factors on the likelihood of buying organic food, as well as the frequency of buying organic food.
