As of October 1, 2009, the population of elderly (persons aged 65 or older) had reached the record high of 29.01 million (28.22 million the previous year), with the percentage to total population (elderly rate) having risen to 22.7% (22.1% the previous year). In addition, it has been estimated that the population of elderly will exceed 30 million by 2015, when every one of the so-called “baby-boom generation” (those born between 1947 and 1949) age group would be elderly, with that number then continuing to increase.
