Disability Statistics and Its Impact on Digital Accessibility

Disability is one of the most common human experiences, yet it remains one of the most overlooked factors in digital design. Understanding disability statistics starts with knowing who lives with a disability, how they interact with technology, and where the web fails them. These patterns directly shape how accessible and usable the modern web actually is

The disability statistics in the U.S. below draw from the CDC, U.S. Census Bureau, WebAIM, and other authoritative sources to give businesses, developers, and compliance teams a clear, current picture of how statistics on disability connect to digital access and legal risk.

General Disability Statistics

These U.S. disability statistics establish the scale of the audience businesses risk excluding when accessibility is treated as optional. Disability is not a niche condition; it is the lived experience of tens of millions of Americans across every age group, income level, and demographic.

When a website fails to meet basic accessibility standards, it does not fail a small edge case. It fails one of the largest consumer segments in the country.

• More than 1 in 4 U.S. adults, approximately 70 million Americans reported having a functional disability in 2022. (CDC, Behavioral Risk Factor Surveillance System, 2022)
• The U.S. Census Bureau puts disability statistics in the United States at 44.68 million civilians of all ages, representing 13.5% of the noninstitutionalized population in 2023. (U.S. Census Bureau, American Community Survey, 2023)
• Globally, 1.3 billion people, 16% of the world’s population, live with a significant disability. (World Health Organization, 2023)
• U.S. disability statistics show that prevalence rises sharply with age: 43.9% of U.S. adults aged 65 and over report a disability, compared to much lower rates in younger age groups. (CDC, BRFSS, 2022)
• 70–80% of all disabilities are invisible and not immediately apparent to others, including cognitive impairments, hearing loss, chronic pain, and mental health conditions. (UK Parliament, POST Research Briefing, 2024)
• 84 million disabled people in the United States use the internet, yet only 26% have access to high-speed internet at home, nearly half the rate of non-disabled Americans. (Pew Research Center)

Disabled People Statistics by Type of Disability

Statistics about disabled people vary significantly by disability type, and so do the digital barriers each group faces. A person with a vision disability navigates the web in a fundamentally different way than someone with a cognitive or mobility impairment, yet most websites fail all of them through the same overlooked errors.

The sections below break down prevalence and digital impact across the four major disability categories tracked by the CDC and U.S. Census Bureau, showing not just how many people are affected, but exactly how inaccessible design creates barriers for each group.

Visual Disabilities

• 8.29 million people in the U.S. have a vision disability, representing 2.5% of the civilian community population. (U.S. Census Bureau, American Community Survey, 2023)
• 5.5% of U.S. adults have a vision disability involving blindness or serious difficulty seeing even with corrective lenses. (CDC, BRFSS, 2022)
• Over 2.2 billion people worldwide have a vision impairment of some kind. (World Health Organization, 2026)
• 55.5% of homepages are missing alternative text for images, directly blocking screen reader users from accessing image-based content. (WebAIM Million, 2025)
• 40.5% of screen reader users primarily use JAWS, 37.7% use NVDA, and 9.7% use VoiceOver on desktop. (WebAIM Screen Reader User Survey #10, 2024)
• 91.3% of screen reader users access the web on mobile devices, where VoiceOver dominates at 70.6% of mobile screen reader usage. (WebAIM Screen Reader User Survey #10, 2024)

Hearing Disabilities

• 12.07 million people in the U.S. live with a hearing disability, representing 3.7% of the civilian population. (U.S. Census Bureau, American Community Survey, 2023)
• 6.2% of U.S. adults are deaf or have serious difficulty hearing. (CDC, BRFSS, 2022)
• 430 million people worldwide experience disabling hearing loss. (World Health Organization, 2025)
• Hearing aid production currently meets less than 10% of global demand. (World Health Organization)
• 430 million people worldwide, over 5% of the global population, require captions and transcripts to access audio and video web content due to disabling hearing loss. (World Health Organization, 2021)
• 80% of people who use captions are not deaf or hard of hearing, showing captions support a much broader audience beyond hearing disabilities. (Ofcom, Access Services Report)

Mobility Disabilities

• 20.78 million people in the U.S. have an ambulatory disability, representing 6.3% of the civilian population. (U.S. Census Bureau, American Community Survey, 2023)
• 12.2% of U.S. adults report a mobility disability with serious difficulty walking or climbing stairs. (CDC, BRFSS, 2022)
• 33.3% of people with mobility impairments use a keyboard or keyboard-like device as their primary means of web navigation, relying on tools such as keyboard navigation, switch controls, and voice recognition software. (WebAIM, Survey of Users with Motor Disabilities, 2013)

Cognitive Disabilities

• 17.97 million people in the U.S. have a cognitive disability involving serious difficulty concentrating, remembering, or making decisions, representing 5.4% of the civilian population. (U.S. Census Bureau, American Community Survey, 2023)
• 13.9% of U.S. adults report a cognitive disability, making it the most prevalent disability type tracked by the CDC. (CDC, BRFSS, 2022)
• Poor heading structure, which appears on 39% of all homepages, creates direct barriers for users who rely on page structure to understand and navigate content. (WebAIM Million, 2025)

Disability Statistics and Digital Accessibility

Disabled people statistics from the U.S. tell only part of the story. The digital landscape compounds the challenge; the web remains largely inaccessible to the very population it should serve. For the tens of millions of Americans living with a disability, online barriers are not an inconvenience. They block access to healthcare information, financial services, job applications, and everyday commerce, despite years of growing awareness, legal pressure, and published standards.

The data below shows that meaningful progress has been slow and the gap between what the web should be and what it actually is remains wide.

• 94.8% of the top one million websites have at least one detectable accessibility failure. (WebAIM Million, 2025)
• The average homepage contains 51 accessibility errors and multiple barriers on every page for every visit. (WebAIM Million, 2025)
• Researchers identified over 50 million distinct accessibility errors across one million analyzed homepages. (WebAIM Million, 2025)
• 45.4% of homepages contain empty or broken links that confuse assistive technologies during navigation. (WebAIM Million, 2025)
• 79.1% of homepages fail minimum color contrast requirements, leaving text unreadable for users with visual impairments. (WebAIM Million, 2025)
• Just six error categories account for 96% of all detected accessibility failures. (WebAIM Million, 2025)
• The WCAG failure rate has improved by only 3.1 percentage points over six years, from 97.9% in 2019 to 94.8% in 2025. (WebAIM Million, 2025)
• 5,114 ADA digital accessibility lawsuits were filed in 2025 across federal and state courts. (UsableNet, 2025 Year-End Report)
• From 2018 to 2025, plaintiffs have filed more than 25,000 digital accessibility lawsuits in the United States. (UsableNet, ADA Lawsuit Tracker)
• Since 2021, plaintiffs have filed more than 4,000 digital accessibility lawsuits every year showing no sign of slowdown. (UsableNet, ADA Lawsuit Tracker)

Disability Statistics That Affect Usability and Website Performance

Disability affects how millions of people experience every element of a website: from how they move through a page to how they read content, complete forms, and interpret visual design.

The disability statistics in the U.S. below go beyond raw prevalence numbers to show exactly where websites fail disabled users and what those failures cost in engagement, conversions, and legal exposure. For businesses, these are not abstract compliance metrics; they are direct indicators of lost revenue and unserved customers.

Disability Statistics and Website Navigation Challenges

• 71.6% of screen reader users navigate web pages primarily by headings, making heading structure one of the most critical accessibility requirements on any site. (WebAIM Screen Reader User Survey #10, 2024)
• 39% of all homepages have skipped heading levels, a structural flaw that breaks content navigation for assistive technology users. (WebAIM Million, 2025)
• 45.4% of homepages contain empty or ambiguous links, making it impossible for screen reader users to know where a link leads before clicking. (WebAIM Million, 2025)
• 71% of people with disabilities abandon a website they find difficult to use. (Click-Away Pound Survey)
• 56% of websites have inaccessible navigation menus, creating significant difficulties for keyboard-only and screen reader users. (WebAIM, The WebAIM Million, 2025)

Disability Statistics and Forms Accessibility

• 48.2% of homepages have form inputs with no descriptive labels, directly blocking users with disabilities from completing essential online tasks. (WebAIM Million, 2025)
• 54% of the most popular e-commerce sites have critical form accessibility failures, including missing labels, unclear error messages, and inaccessible CAPTCHA. (Baymard Institute)
• Users with disabilities who encounter form errors are rarely given clear instructions on how to fix them, forcing most to either abandon the form or seek outside help. (W3C/WAI, Understanding WCAG 2.1)
• 45.4% of homepages contain empty or broken links, the same structural failures that make form navigation unpredictable for keyboard and screen reader users. (WebAIM Million, 2025)
• Users with motor and cognitive disabilities are disproportionately impacted by time-limited forms and session timeouts, which WCAG 2.1 Success Criterion 2.2.1 addresses. (W3C, WCAG 2.1)
• 29.6% of homepages contain buttons with no descriptive text, making them completely unusable for screen reader users. (WebAIM Million, 2025)

Disability Statistics and Content Accessibility

• 13.9% of U.S. adults have a cognitive disability that affects their ability to process complex language, dense text, or non-linear content structures. (CDC, BRFSS, 2022)
• 39% of homepages have skipped heading levels, depriving cognitively disabled users of the structural cues they depend on. (WebAIM Million, 2025)
• 5.4% of the U.S. civilian population nearly 18 million people has a cognitive disability affecting concentration, memory, or decision-making. (U.S. Census Bureau, American Community Survey, 2023)
• 54% of U.S. adults read below a 6th-grade level, making complex or jargon-heavy content difficult to understand. (U.S. Department of Education, PIAAC)

Disability Statistics and Visual Design Barriers

• 79.1% of homepages fail WCAG minimum color contrast requirements, the single most common accessibility failure on the web. (WebAIM Million, 2025)
• The average failing homepage has 29.6 low-contrast instances per page, creating repeated visual barriers throughout the user experience. (WebAIM Million, 2025)
• 5.5% of U.S. adults have serious difficulty seeing even with corrective lenses, and millions more have low vision that makes low-contrast text difficult or impossible to read. (CDC, BRFSS, 2022)
• Over 300 million people worldwide have color vision deficiency, making color-dependent design a persistent and widespread barrier. (Colour Blind Awareness)
• WCAG requires a minimum contrast ratio of 4.5:1 for normal text and 3:1 for large text standards that the vast majority of websites still fail to meet. (W3C, WCAG 2.1)
• WCAG requires that text can be resized to 200% without loss of content or functionality. (W3C, WCAG 2.1)

Disability Statistics and Website Abandonment

The business case for accessibility becomes clear when you look at what inaccessible design costs. Statistics on disability and digital behavior consistently show that barriers drive users away and to competitors.

• 69% of disabled online consumers click away from websites they find difficult to use due to their disability. (Click-Away Pound Survey, 2019)
• 83% of disabled users limit their online shopping exclusively to sites they already know are accessible. (Click-Away Pound Survey, 2019)
• People with disabilities hold nearly half a trillion dollars in disposable income in the United States alone. (Accenture, The Disability Inclusion Imperative, 2023)
• Companies that lead in disability inclusion generate 1.6 times more revenue and 2.6 times more net income than their peers. (Accenture, The Disability Inclusion Imperative, 2023)
• 79% of users who encounter a poor mobile experience visit a competitor’s site instead. (McKinsey)
• 36% of companies sued in the first half of 2025 had annual revenue exceeding $25 million up from 33% in 2024, showing plaintiffs are increasingly targeting larger businesses. (UsableNet, 2025 Midyear Report)
• 1,427 of the 5,000+ lawsuits filed in 2025 targeted companies already sued before with repeat defendants accounting for 46% of federal cases. (UsableNet, 2025 Year-End Report)
• Over 1,000 businesses were sued in 2024 despite having accessibility widgets on their websites, accounting for more than 25% of all cases confirming widgets provide no meaningful legal protection. (UsableNet, 2024 Year-End Report)
• Among the top 500 e-commerce retailers, 35.8% received at least one ADA accessibility lawsuit. (UsableNet, 2025 Year-End Report)
