In 1950, less than 1% of the global population was aged over 80 years. By 2050, the share of those aged 80 years and over is expected to increase from 4% in 2010 to nearly 10% across OECD countries. This population ageing is being accompanied
by family ties becoming looser. The need for community involvement in the care for frail and disabled seniors is growing and will do so ever more rapidly in OECD countries.
