The accelerated ageing of the populations of developed countries is being matched in the developing world. In fact, in 2017, for the first time in history, the number of persons aged 65 and over will outstrip those aged 5 and under. This population trend is not just a temporary blip, not just due to a short-term outcome of the baby boomer generation.
All over the world, populations are changing. People are living longer, and older people are forming a larger percentage of the global population. Baby boomers are retiring and improved health care has extended life expectancy. At the same time, as globalisation and urbanisation break apart familiar social and family structures, more older adults are living alone or without social support.
