Disability affects hundreds of millions of people worldwide, spanning children and adults with conditions such as vision and hearing loss, intellectual disabilities, injury-related risks, and mental health disorders. As you scroll, you’ll see how health-service barriers can lead to undercounting, why many people still face obstacles to healthcare and assistive technology, and how unmet needs ripple into lost healthy years, preventable death risk, poverty, and employment disadvantage.

- $2.6 billion — global market size for smart hearing aids in 2023 (assistive hearing tech market)
- Approximately 1 in 4 adults in the UK (25%) reported a disability in the 2017–2018 Health Survey for England.
- 10.5% of the global population are estimated to have vision impairment, according to The Lancet Global Health commission’s systematic review (GBD-based estimates for vision loss).
- 5.3% of the global population are estimated to have hearing loss (moderate to severe), according to a GBD-based analysis published in The Lancet Global Health (2018).
- 46% of respondents with disability reported barriers to accessing assistive technology-related services in a 2018 multi-country study using the Washington Group/UNICEF disability modules (reported in Disability and Rehabilitation: Assistive Technology).
- A 2018 systematic review found people with disabilities had a 2.0x higher risk of experiencing health inequities (relative risk/odds ratio range across studies) compared with non-disabled people.
