This century has seen an enormous growth in the population aged 65 years and older. Future projections indicate that there will be increases in both the number of older persons and the proportion of the total population that is elderly. In this article, population characteristics and mortality and morbidity patterns are discussed. Consideration is given to the present and future impact that demographic changes in the elderly will have on health care utilization and expenditures.
本世纪，65岁及以上老年人口数量大幅增长。未来预测表明，老年人数量及老年人口在总人口中所占比例都将增加。本文将讨论人口特征以及死亡率和发病率模式。同时还会考虑老年人的人口结构变化对当前及未来医疗保健利用和支出的影响。
