As a result of healthier diets and
lifestyles, Japanese live longer than most of the world's people. This
fact, combined with the trend towards families having fewer children
means that Japan is "graying." This is also happening in some
European countries and to a lesser extent in the United States, but not
nearly as quickly as in Japan. By 2020, as the chart to the right shows,
over one quarter of Japanese will be over age 65.
