The Demographics of Disability: Prevalence, Aging, and Care Needs
Quick fact
In most countries, disability prevalence among people aged 65 and older is two to five times higher than among younger adults, and as the global population over 65 is projected to double by 2050, the number of older people with disability could surge from around 300 million to over 600 million.
Why this is interesting
Most of us assume disability is a personal health issue, but at the population level it is a pattern that shifts dramatically with age—and the world is about to see a massive shift.
