The world’s population is ageing fast. In 2020, 1 billion people in the world were aged 60 years or over. That figure will rise to 1.4 billion by 2030, representing one in six people globally. By 2050, the number of people aged 60 years and over will have doubled to reach 2.1 billion. The number of persons aged 80 years or older is expected to triple between 2020 and 2050 to reach 426 million (1).
Older adults contribute to society as family and community members, and many are volunteers and workers. While most have good health, many are at risk of developing mental health conditions such as depression and anxiety disorders. Many may also experience reduced mobility, chronic pain, frailty, dementia or other health problems, for which they require some form of long-term care. As people age, they are more likely to experience several conditions at the same time.
