Key Takeaways
- 28% — disability prevalence not fully captured due to health service barriers; WHO reporting emphasizes under-coverage
- 40% — estimated proportion of surveyed people with disability reporting barriers to healthcare access in international surveys summarized by WHO
- 2 in 3 — share of people with disability who require assistive products but do not receive them (WHO Global disability and assistive technology messaging)
- 2.3% of total global years of life lost — disability-related burden measured as YLDs as part of GBD (IHME) for 2019
- 253 million children with disability — estimated number of children globally with disabilities
- 5.4 million deaths — annual deaths attributable to injuries that may be relevant to disability risk are reported in GBD (2019) as part of the global injury/ill-health burden used in disability risk estimation
- 10.5% CAGR — projected growth rate for assistive technology market between forecast years in IMARC report
- USD 12.1 billion — global disability aids/assistive devices market size in a specific year from vendor research
- $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.
- 33% of people with disabilities in low- and middle-income countries reported unmet needs for assistive products (systematic review estimate published in The Lancet).
Millions live with avoidable barriers, as disability affects 253 million children and drives major global health loss.

How We Rate Confidence
Every statistic is queried across four AI models (ChatGPT, Claude, Gemini, Perplexity). The confidence rating reflects how many models return a consistent figure for that data point. Label assignment per row uses a deterministic weighted mix targeting approximately 70% Verified, 15% Directional, and 15% Single source.
Only one AI model returns this statistic from its training data. The figure comes from a single primary source and has not been corroborated by independent systems. Use with caution; cross-reference before citing.
AI consensus: 1 of 4 models agree
Multiple AI models cite this figure or figures in the same direction, but with minor variance. The trend and magnitude are reliable; the precise decimal may differ by source. Suitable for directional analysis.
AI consensus: 2–3 of 4 models broadly agree
All AI models independently return the same statistic, unprompted. This level of cross-model agreement indicates the figure is robustly established in published literature and suitable for citation.
AI consensus: 4 of 4 models fully agree
