Red meats, poultry, and fish are the most important foods in most consumer's diets, and are of major importance to the Nation's agricultural economy. This report contains evidence that the U.S. demand structure for red meats, poultry, and fish is characterized by a high degree of stability, and that an overwhelming part of the variation in U.S. demand for these products can be explained by the economic factors of prices and income. Socioeconomic and demographic factors which are important determinants of individual consumer demand patterns are also identified; and their effects are measured, and assessed.
