Final answer:
When marketing research indicates a group has no desire for a product, they are not a market for that product, as a market is defined by both the desire and ability to purchase.
Step-by-step explanation:
When marketing research shows that a group of people does not desire a particular product, the people in that group are not a market for the product. The concept of a market in the context of business and economics refers to a group of consumers who have both the willingness and the ability to purchase a product or service. Without the desire for the product, even if they have the ability to buy, there isn't an effective demand, and therefore, they do not constitute a viable market for that product.
This situation reflects key factors that affect demand, including tastes and preferences and income. For instance, demand for a product could decrease if people's preferences change due to information or social trends. On the other hand, an increase in income typically increases demand for most goods and services; a decrease would similarly decrease demand.
