In 1993 Taiwan became an aged society as defined by the UN. The over-65 population reached 7 % of the total, some 1.9 million people. Today, ten years later, the proportion of old people has increased to 11.6 %. The Council for Economic Planning and Development estimates that by 2031 this proportion will rise to 23 %, for an elderly population of more than 5.6 million people.
一九九三年，台灣正式跨入聯合國定義的高齡化社會，六十五歲以上人口達到 7％、一百四十八萬人，十年後，老人比例已增至 9.4 %；行政院經建會預估，到了二○三一年（民國一百二十年），比重將升至 23％，老年人口數增加為五百六十餘萬人。
