The demographic features have been proposed as an important factor for determining the quantity and quality of food consumption. The increase in population brings about the rise of food consumption, and the change of age structure tends to lead the change of a food consumption pattern, despite of the same population scale. Therefore, the change of age groups in population appears to be a crucial variable in explaining the changing food demand. When the food consumption pattern changes toward the aging population along with income and population age structure, the intake of carbohydrate decreases whereas the consumption of protein food tends to increase.
The main purpose of this study lies in analyzing the impacts of price, income and age structure on the change in general food consumption patterns and their impact on sea food demands. The demand functions of fish, shellfish, sea weeds, rice, and livestock meat were estimated by auto/ridge regression methods. The results showed that all own price elasticities have negative values, which are consistent with economic theories. Income elasticities except for shellfish turned out to be positive. Both of the own price and income elasticity of rice appeared to be lower than those of seafood and meat.
The population elasticities of fish by different ages appeared to be positive in the range of 40～59 and above 60, while the shellfish and seaweed elasticities were positive in above 60. This implies that the increase of population in the relevant age range has significant influence on food consumption. As seen in the meat demand, it tends to increase in all age groups, but the rice demand showed a decrease for the data period in the range of 40～59 but an increase in above 60. The overall results suggest that seafood is preferred by the elderly group population over other age groups.
This research used only age group data because of very limited information on other socio-population characteristics such as income, region, education and so on, that may have an important influence on the demand for seafood. Thus, such comprehensive analysis of including such socio-demographic factors is left for further research.
