Disability is not rare. An estimated one billion people or around 15 per cent of the world’s populationhave some form of disability (WHO & World Bank, 2011). Disability is more common in low- and middle-income countries than in high-income countries, and among older age groups (WHO & World Bank, 2011; Mitra & Sambamoorthi, 2014). Disability is something everyone is likely to experience, either permanently or temporarily, at some point in their life (WHO & World Bank, 2011). People with disabilities are diverse and not defined by their disability.
