Predicted median age of the population, selected countries, in 2015 and 2030: Now, the median age of the population—the point at which half the people are younger and half are older—is 45-plus in Italy, Germany, and Japan. Also, notice how high the median ages in these nations will be in 2030. How do you think living in these “most-aged nations” will affect residents’ daily lives?
