[math-fun] the rising ratio

From The Economist, 28 July 2007, pg 25, "Japan's changing demography:"

* * * By 2030, demographers say, Japan will have just two working-age people for each retired one; by mid-century, short of a rapid and unlikely return to fecundity, the ratio will rise to three for every two retirees. * * * [ seems wrong to me, but i guess a reading that has it comparing 1/2 to 2/3 is possible ] -- Thane Plambeck tplambeck@gmail.com http://www.plambeck.org/ehome.htm
