The aging of the global population will be a hallmark of the 21st century, when average lifespan may reach 100 years in some countries, at least for women.1 Worldwide, the proportion of the population aged 60 years or older is expected to increase from 10% worldwide in 2005 to 22% in 2050, with the steepest rise in the next 25 years.2 Individuals aged 85 years or older are the most rapidly increasing segment of many populations. By 2100, more than half of the population of Japan will be aged 60 years or older, as will more than one-third of individuals in every region except sub-Saharan Africa.2
