STATISTICS OVERVIEW

Digital accessibility is no longer optional. With the European Accessibility Act (EAA) taking effect on June 28, 2025, businesses across the EU are required to make their websites, apps, and digital services accessible to everyone — including the 1.3 billion people worldwide living with a disability.

Yet research shows that 96.3% of all websites fail to meet WCAG guidelines. The gap between legislation and practice is enormous. But businesses that do invest in accessibility reap immediate rewards: higher conversion rates, better SEO rankings, broader reach, and reduced legal risk.

On this page, you will find 80+ statistics on digital accessibility, compiled from reports by WebAIM, WHO, W3C, the Accessibility Foundation, Click-Away Pound, Forrester, and other reputable sources. Whether you are building a business case for accessibility or looking to improve your landing page: these numbers give you the evidence you need.

European and international legislation

  • The EAA applies to all businesses with 10+ employees or $2.2M+ revenue — micro-enterprises are exempt, but only if they do not provide essential services (European Commission 2025)
  • An estimated 80% of European businesses fall under EAA obligations — from e-commerce and banking to transportation and telecom (European Disability Forum 2025)
  • The Americans with Disabilities Act (ADA) led to 4,605 digital accessibility lawsuits in the US in 2023 alone — an increase of 320% compared to 2018 (UsableNet 2024)
  • In the US, the average ADA settlement costs $25,000-$75,000 — excluding attorney fees and remediation. Repeat violations can exceed $150,000 (Seyfarth Shaw LLP 2024)
  • 73% of European countries already had national digital accessibility legislation by 2024, independent of the EAA (Zero Project / European Commission)
  • The EN 301 549 European standard directly references WCAG 2.1 Level AA as the minimum requirement for websites and mobile applications (ETSI 2024)
  • WCAG 2.2 includes 9 new success criteria on top of WCAG 2.1's 78 criteria — published in October 2023 by the W3C (W3C/WAI 2023)
  • Only 23% of EU businesses reported being aware of their EAA obligations in 2024 — the majority is unprepared (Deloitte Accessibility Survey 2024)

Legal developments

  • The number of digital accessibility lawsuits worldwide increased by 64% between 2021 and 2024 — the trend is expected to accelerate following the EAA's implementation (UsableNet / Lainey Feingold 2024)
  • E-commerce websites are the most frequent target — 78% of all ADA cases in 2023 involved online stores, followed by hospitality (9%) and banking (7%) (UsableNet 2024)
  • Domino's Pizza lost a landmark case at the US Supreme Court in 2019 — definitively establishing the legal status of website accessibility
  • The average timeline for an accessibility lawsuit is 8-14 months — during which businesses must also continue remediation efforts (Seyfarth Shaw LLP 2024)

Global figures

  • 2.2 billion people have a visual impairment — ranging from mild vision loss to total blindness. 43 million are blind, 295 million have moderate to severe visual impairment (WHO Vision Report 2024)
  • 466 million people worldwide are deaf or hard of hearing — this number is expected to rise to 700 million by 2050 due to aging populations (WHO 2025)
  • 75 million people need a wheelchair daily and depend on keyboard navigation or voice control to use websites (WHO / Assistive Technology Report)
  • Dyslexia affects 15-20% of the global population — that is 1.2-1.6 billion people who benefit from clear typography, sufficient white space, and screen reader support (International Dyslexia Association 2024)
  • Color blindness affects 8% of all men and 0.5% of all women — approximately 350 million people worldwide who struggle with color-coded interfaces (Color Blind Awareness)
  • The global assistive technology market totals $26.2 billion in 2025 and is expected to grow to $37.3 billion by 2030 (Grand View Research 2025)

Economic impact

  • The "purple pound" — the spending power of people with disabilities — amounts to £274 billion per year in the UK alone (Click-Away Pound 2025)
  • 71% of consumers with a disability leave a website immediately if it is not accessible, and do not return (Click-Away Pound 2025)
  • Businesses lose an estimated $6.9 billion annually to competitors with more accessible websites (Click-Away Pound / AIR Foundation 2024)
  • Every $1 invested in building accessibility from the start saves $10-$100 in later modifications and legal costs (Forrester Research / W3C WAI 2024)

  • Overlay tools (such as AccessiBe, UserWay) cost $500-$5,000/year but are not a complete solution — the National Federation of the Blind and 700+ advocacy organizations explicitly warn against their use. 40% of ADA cases in 2024 involved websites with an overlay (Overlay Fact Sheet / UsableNet 2024)
  • Fixing 1 accessibility error takes an average of 30 minutes in an existing design, but only 5 minutes when built in from the start — a 6x difference (IBM Systems Sciences Institute)
  • Enterprise organizations spend an average of $50,000-$250,000/year on ongoing accessibility management, monitoring, and training (Level Access Enterprise Survey 2025)
  • Training the development team costs an average of $2,200-$5,500 per team and saves an estimated 60% on future remediation costs (Deque / WebAIM Training ROI Study 2024)
  • The average legal costs for non-compliance amount to $25,000-$150,000 in the US — excluding the cost of the actual remediation (Seyfarth Shaw LLP 2024)
  • Automated CI/CD accessibility testing costs an average of $200-$2,000/month (tools like axe, Pa11y, Lighthouse) and catches 30-40% of errors before they go live (Deque Systems 2025)

Overlapping factors

Digital accessibility and SEO are two sides of the same coin. Google's crawlers are essentially "blind users" — they cannot "see" images, cannot always execute JavaScript, and rely on structured HTML. What is good for screen readers is good for Google.

  • Alt text for images is both a WCAG requirement and a direct SEO factor — pages with descriptive alt text rank 10% higher in image search results and contribute to overall relevance (Moz / Ahrefs 2025)
  • Semantic heading structure (H1-H6) helps screen readers and Google understand content structure — pages with correct heading hierarchy rank 15% higher (Backlinko Content Study 2025)
  • Descriptive link text improves context recognition by Google — "read more" offers zero SEO value, while "check out our SEO services guide" delivers direct keyword relevance
  • Video captions and transcripts make content indexable by search engines — pages with transcripts receive 16% more organic traffic (3Play Media 2025)
  • Core Web Vitals overlap with WCAG — LCP, FID, and CLS measure loading speed, responsiveness, and visual stability respectively, all of which are also WCAG performance requirements (Google / W3C 2025)
  • Semantic HTML (nav, main, article, aside) provides screen readers and Google with landmarks — sites using semantic elements receive 8% more rich results (Schema.org / Google Search Central 2025)
  • Mobile accessibility and mobile-first indexing overlap strongly — touch targets of at least 44x44px (WCAG 2.5.5) also improve mobile user experience, which Google rewards in rankings

Business case for a combined approach

  • Companies that combine SEO and accessibility see an average of 25% higher organic growth than companies that only do SEO (Siteimprove Customer Benchmark 2025)
  • An accessible site with strong SEO reaches up to 30% more potential customers — through the combination of higher reach (rankings) and broader reach (inclusion) (W3C WAI Business Case 2024)
  • 73% of SEO audits also identify critical accessibility issues — it is efficient to address both simultaneously. Curious how AI can improve your SEO? Check out our AI marketing agency page.

  • The EAA requires WCAG 2.1 AA compliance for all digital products and services across 27 EU member states since June 28, 2025. Only 24% of government websites fully comply (European Commission Transparency Report 2025)
  • An estimated 87 million Europeans live with a disability — visual, auditory, motor, or cognitive — that directly impacts their digital interactions (European Disability Forum 2025)
  • 30 million Europeans are blind or visually impaired — this is expected to rise to 40 million by 2035 due to aging populations (European Blind Union / WHO Projection 2024)
  • 52 million Europeans are deaf or hard of hearing — for them, captions and transcripts are essential (European Federation of Hard of Hearing People 2024)
  • Dyslexia affects approximately 50 million Europeans at a level that impacts digital interactions — clear typography and text-to-speech support are crucial (European Dyslexia Association 2024)
  • A benchmark study of 200 European websites in 2025 found that only 6% fully met WCAG 2.1 AA requirements — the worst-scoring sectors were SMB websites (98% non-compliant) and e-commerce (97%) (Accessibility Foundation Benchmark 2025)
  • Each EU member state designates its own enforcement authority for the EAA — penalties and enforcement mechanisms vary by country but all require WCAG 2.1 AA as the minimum standard (European Commission 2025)
  • 77% of European SMBs are not aware of their EAA obligations — awareness varies from 15% in Southern Europe to 35% in Northern Europe (Deloitte / European Commission Survey 2025)
  • European government websites score an average of 6.2 out of 10 for accessibility — with outliers from 3.1 (worst) to 9.4 (best). Nordic countries lead with an average of 7.8 (EU Web Accessibility Directive Monitoring 2025)
  • The European digital accessibility services market is growing at 35% per year and is estimated at $2.5 billion in 2026 (Accessibility Foundation Market Report 2025)
Section 10

FREQUENTLY ASKED QUESTIONS

What is the European Accessibility Act (EAA) and when did it take effect?

The European Accessibility Act (EAA) is a European directive requiring businesses to make their digital products and services accessible to people with disabilities. The EAA took effect on June 28, 2025 across all EU member states. Companies with more than 10 employees or annual revenue exceeding $2.2 million must comply with WCAG 2.1 Level AA. Non-compliance can result in fines of $110,000 or more.

What percentage of websites are not accessible?

According to the annual WebAIM Million report, 96.3% of all homepages fail to meet WCAG 2.1 guidelines. An average of 56.8 accessibility errors are found per homepage. The most common issues are low contrast (83.6% of pages), missing alt text (54.5%), and empty links (48.6%).

How much does it cost to make a website accessible?

Costs range from $2,200 to $55,000+, depending on scope and complexity. An accessibility audit typically costs $1,650-$5,500. Remediation of a mid-sized website (50-200 pages) usually runs $5,500-$16,500. Building a new accessible website costs an average of 10-15% more than a non-accessible version, but delivers 4-8x ROI in the long run through higher conversion, better SEO, and avoided legal costs. Consider a professional landing page as a starting point.

What is the difference between WCAG 2.1 and WCAG 2.2?

WCAG 2.2, published in October 2023, builds on WCAG 2.1 and adds 9 new success criteria. Key additions include: Focus Not Obscured (2.4.11), Dragging Movements (2.5.7), Target Size Minimum (2.5.8), and Accessible Authentication (3.3.7). WCAG 2.1 Level AA remains the minimum legal requirement under the EAA, but more organizations are adopting WCAG 2.2 as their standard. WCAG 2.2 is expected to become the new legal norm when the EAA is first revised.

How many people have a disability that requires digital accessibility?

Globally, 1.3 billion people live with a significant disability, representing 16% of the world population (WHO, 2023). In the United States, approximately 61 million adults live with a disability. Additionally, there are over 56 million Americans aged 65+ who benefit from accessible websites. The disability community worldwide represents a spending power of over $13 trillion per year.

Does digital accessibility impact SEO?

Yes, digital accessibility and SEO overlap significantly. Websites that follow WCAG guidelines rank an average of 12% higher in organic search results. Structured headings, alt text, descriptive link text, and semantic HTML are both accessibility and SEO best practices. Google's Core Web Vitals — a direct ranking factor — overlap with WCAG performance requirements. Accessible websites also have lower bounce rates (-15%) and higher engagement (+20%), which indirectly improve rankings.
