The graying of the planet (proportionately) is due to a number of changes in population growth. One factor is the increasing number older adults. Another factor is the decreasing fertility rate world-wide. Fewer children are being born among all of the industrialized countries of the world. Regardless of country or culture, from 1950 to the year 2000, the number of children being born per woman declined from 5 to 2. In many European countries, the indigenous population is not replacing itself. In Italy, for example, some towns have too few children to continue the operation of their schools. America's influx of foreign nationals as well as sustained family formation will continue to enlarge the total number of younger people - but their proportion in relation to older adults is diminishing.
