A “demographic check” system should monitor and anticipate changes from lowering fertility rates, increasing ageing of population, increasing youth unemployment, and the complexity of urban-rural shrinkage. Some Asian countries are fast becoming an elderly society. Japan, for example, will top 25% of the population aged sixty-five or over by 2015. In light of this rapid demographic change new opportunities emerge in the areas of the so called “silver economy” where new technologies, products and services are being designed for and, sometimes by, the senior population.
