Japan has the most rapidly aging population among developed countries. A number of factors contribute to this trend. The Japanese population has the longest life expectancy and one of the lowest birth rates in the world, and immigrants constitute a very small proportion of the population. Japan’s National Institute of Population and Social Security Research (NIPSSR) projects that the nation’s population will decline by half between 2006 and 2100. Over this period the elderly dependency ratio will increase rapidly—based on the NIPSSR projections, for every person above 65 there will be only 1.5 people of working age in 2050 (Figure 6.1).
