Rapid growth has been observed in the fresh blueberry market since 2000, but at the same time, there is no obvious consumption increase in the market for frozen blueberries. In this study, we analyze the different consumer structures in the fresh and frozen blueberry markets by classifying consumers into “buyers”, “potential buyers” and “non-buyers” of blueberries. A double hurdle count data model is used. The results show that while the fresh blueberry market is mainly composed of buyers, most of the consumers in the frozen blueberry market are non-buyers. The difference in growth trends may be due to the fact that it is more difficult to convert non-buyers to buyers than to increase consumption of buyers.
