Global elderly care in crisis
The Lancet
Preview |
The world’s population is ageing rapidly at an unprecedented rate. The proportion of people aged over 60 years will double from about 11% to 22% between 2000 and 2050. Population ageing has profound implications for the burden of disease and social and health-care systems. How well prepared are countries to cope with these changing demographics? Unfortunately, current elderly care systems worldwide are already unable to address the soaring demand from fast growing numbers of older people, even in higher-income countries.
