About These Reports
The Digital Analytics Program (DAP) is a U.S. government analytics service that collects website traffic data across participating federal agencies. DAP tracks page views, visitor counts, and usage patterns for hundreds of government websites, providing transparency into how the public engages with federal digital services. The traffic data is publicly available at analytics.usa.gov.
This report measures the quality and accessibility of the top 100 most-visited U.S. government URLs as reported by DAP. Each day, Lighthouse scans are run against these URLs to measure:
- Performance - How fast pages load for users (scores 0-100, higher is better)
- Accessibility - How well pages work for users with disabilities, following WCAG guidelines (scores 0-100, higher is better)
- Best Practices - Whether pages follow modern web development standards (scores 0-100, higher is better)
- SEO - How well pages are optimized for search engines (scores 0-100, higher is better)
Accessibility findings come from axe-core, the industry-standard accessibility testing engine embedded in Lighthouse. The axe findings surface specific WCAG violations such as missing alternative text, insufficient color contrast, and missing form labels that make government websites harder to use for people with disabilities.
Traffic data reflects daily visitor counts from DAP. URLs are ranked by page load count, ensuring the most-used government pages are prioritized for quality measurement.
Accessibility Trend Narrative
Over the past 30 days of data (2026-04-24 to 2026-05-23), government website accessibility scores have improved (+0.53 points, from 91.85 to 92.38). Performance scores have declined (-2.81 points, from 54.25 to 51.44).
Today's aggregate accessibility score of 92.29 reflects the mean Lighthouse accessibility score across 93 successfully scanned government URLs. A score above 90 indicates generally strong compliance with WCAG automated checks, though manual testing is always recommended to fully assess accessibility.

Human impact narratives for top issues
The following narratives describe the real-world impact of each accessibility barrier on people with disabilities. These barriers are not abstract technical failures; they prevent citizens from independently accessing government services.
target-size: Digital Motor Access
Small touch targets act as a digital gatekeeper, excluding individuals with tremors, arthritis, or limited dexterity from accessing essential services independently. These technical failures transform a routine interaction into a source of failure, stripping away the autonomy of citizens who require a frictionless, accessible interface to participate in digital life. The approximately 58 million Americans with ambulatory or self-care disabilities are disproportionately impacted by inadequate touch target sizing on government mobile websites.
Affected groups:
- People with Parkinson's disease, arthritis, or hand tremors
- Older adults with reduced fine motor control
- People with motor disabilities using alternative pointing devices
- People in situational impairment contexts (e.g., commuting, holding a child)
heading-order: Document Structure Navigation
Screen reader users navigate complex government websites primarily through heading structure, using headings as a table of contents to jump between sections. Skipped heading levels break the logical document outline, causing confusion about the hierarchy of information and forcing users to re-read sections to understand the relationship between topics, adding significant time and effort to information-gathering tasks.
Affected groups:
- People who are blind using screen readers
- People who are deaf and rely on visual-to-text tools
- People with motor disabilities using keyboard navigation
landmark-one-main: Primary Content Identification
Without a main landmark, screen reader users lose their most efficient way to skip to the primary content of a government page. Every page visit requires tabbing through the entire navigation structure to reach the actual content, a significant time and effort burden that accumulates across repeated visits to government websites for citizens managing ongoing benefit cases or legal matters.
Affected groups:
- People who are blind using screen readers
- People who are deaf and rely on visual-to-text tools
- People with motor disabilities using keyboard navigation
label-content-name-mismatch: Voice Control Activation
When the accessible name of an element does not match its visible text, voice control users cannot activate it using the words they see on screen. Saying "click Submit" to a button whose visual label is "Submit" but whose accessible name is "submitbtn" results in no action. This mismatch silently breaks voice control for citizens with motor disabilities who depend on this input method to interact with government websites.
Affected groups:
- People who are blind using screen readers
- People with low vision relying on screen magnifiers
- People who are deaf using keyboard navigation
- People with motor disabilities using voice control software
color-contrast: Visual Information Access
Low contrast text is one of the most pervasive barriers on government websites, rendering critical information invisible to the approximately 26 million Americans with low vision or color blindness. When agency announcements, form instructions, error messages, or legal notices are displayed in insufficient contrast, affected citizens are denied equal access to the information they need to exercise their rights and access public services.
Affected groups:
- People with low vision including age-related vision loss
- People who are color blind (approximately 8% of men, 0.5% of women)
link-name: Link Purpose Clarity
Links without accessible names are completely useless to screen reader users who navigate government pages by jumping between links. An unnamed link could lead anywhere, and activating it unknowingly could trigger downloads, open unexpected pages, or initiate unintended processes. On government websites, unnamed links undermine the informed consent principle by preventing citizens from knowing where a link will take them.
Affected groups:
- People who are blind using screen readers
- People who are deaf and rely on visual-to-text tools
- People with motor disabilities using keyboard navigation
image-alt: Visual Content Access
Images without alternative text are completely invisible to blind users and to search engines. On government websites, informational images, diagrams, infographics, and document screenshots without alt text deprive blind citizens of the same information available to sighted visitors. Critical details like emergency instructions, benefit eligibility charts, or form procedure diagrams can be entirely inaccessible, putting these citizens at a disadvantage in accessing government services and information.
Affected groups:
- People who are blind using screen readers
- People who are deaf and rely on visual-to-text tools
aria-required-children: Widget Structure Integrity
ARIA composite widgets without the correct child roles create structurally broken interfaces for screen reader users. Menus without menu items, lists without list items, and grids without cells all degrade to incoherent structures, making navigation impossible and forcing blind users to abandon complex interactive government tools.
Affected groups:
- People who are blind using screen readers
- People who are deaf and rely on visual-to-text tools
- People with motor disabilities navigating by keyboard
listitem: List Item Semantic Context
Orphaned list items outside of list containers lose their semantic meaning and list navigation properties. Screen reader users rely on list structure to understand that a set of items is related and to count the total number of items. Government navigation menus, step lists, and option groups presented as invalid lists are harder to parse and navigate efficiently.
Affected groups:
- People who are blind using screen readers
- People who are deaf and rely on visual-to-text tools
- People with motor disabilities navigating by keyboard
aria-required-parent: Widget Context Integrity
ARIA elements without their required parent context lose semantic meaning for screen readers. A list item without a list, or a tab panel without a tab list, strips away the structural context that screen reader users depend on to understand and navigate government websites. This disorientation forces repeated and often futile navigation attempts.
Affected groups:
- People who are blind using screen readers
- People who are deaf and rely on visual-to-text tools
- People with motor disabilities navigating by keyboard

Performance Impact on Americans
Google defines a good Largest Contentful Paint (LCP) as under 2.5 seconds and recommends pages under 1.6 MB. The figures below estimate how much extra time Americans spend waiting, and how much extra data is transferred, because government websites fall short of these benchmarks. Calculations are based on 93 successfully scanned URLs with Lighthouse timing data.
| Metric | Estimated total (May 24, 2026) | Notes |
|---|---|---|
| Extra time waiting (vs 2.5s LCP benchmark) | 9 years, 3 months, 8 daysExtra time is calculated as: for each scanned URL, max(0, actual LCP − 2.5s) × page loads. Total: 292,649,638 seconds. | 292,649,638 seconds |
| Extra data transferred (vs 1.6 MB page weight benchmark) | ~64.5 TB (2,685 copies of Wikipedia)Extra data is calculated as: for each scanned URL, max(0, actual page weight − 1.6 MB) × page loads. | Across 93 URLs with weight data |
LCP and page weight are measured by Lighthouse. Wikipedia copy count uses a size of 24.05 GB per Wikipedia:Size of Wikipedia. These are rough estimates based on a sample of the top government URLs by traffic. Hover or focus the estimated totals for calculation details.
Content Density (Words per Megabyte)Experimental
Words-per-Megabyte (WpM) measures how efficiently a page delivers readable content relative to its total download size. A low ratio indicates Digital Bloat—the page transfers far more data than the text it contains. Pages below 200 WpM are flagged for optimization review.
- URLs with content metrics: 67
- Average word count: 219
- Average Words/MB: 102
- URLs below 200 WpM threshold: 60

How this is calculated: Word counts are extracted from the page’s main article content using Mozilla Readability, which strips navigation, sidebars, and ads (falling back to full visible body text for pages with fewer than 50 readable words). Page weight is the total resource size in bytes measured by Lighthouse across all network requests, converted to megabytes (1 MB = 1,000,000 bytes). The ratio is computed as word count divided by total MB, rounded to the nearest integer. Pages below 200 WpM may impose unnecessary data costs on users on metered connections. Note: This metric is experimental—the 200 WpM threshold and overall methodology are still being refined and may change in future reports.
Environmental conditions and situational disability
Environmental conditions can create temporary or situational disabilities. High pollen, particle pollution, and poor air quality can cause irritated eyes, blurred vision, headaches, fatigue, and reduced concentration. On days like this, people may rely more heavily on zoom, contrast, clear headings, plain language, keyboard navigation, and error-tolerant forms.
Signal level: High — Environmental conditions are likely affecting people across many major U.S. metro areas.
- Metro areas with AQI ≥ 101 (air pollution): 0
- Metro areas with PM2.5 AQI ≥ 101 (particle pollution, which may include smoke): 0
- Metro areas with high or very high pollen: 41 (source: Seasonal estimate (not live data))
Pollen-affected metro areas (up to 10 shown)
- New York: TREE, GRASS (seasonal)
- Los Angeles: TREE, GRASS (seasonal)
- Chicago: TREE, GRASS (seasonal)
- Houston: TREE, GRASS (seasonal)
- Phoenix: TREE, GRASS (seasonal)
- Philadelphia: TREE, GRASS (seasonal)
- San Antonio: TREE, GRASS (seasonal)
- San Diego: TREE, GRASS (seasonal)
- Dallas: TREE, GRASS (seasonal)
- San Jose: TREE, GRASS (seasonal)
Pollen conditions are based on Google Pollen data when available. When live data is unavailable, a seasonal estimate is used. This is a situational signal, not a medical or exposure model.
Data source notes
- Air quality data unavailable (AIRNOW_API_KEY not configured).

Section 508: Legal Requirements vs. Best Practices
Section 508 of the Rehabilitation Act was enacted in 1998 and requires U.S. federal agencies to make their electronic and information technology accessible to people with disabilities. The technical standards were significantly updated through the ICT Accessibility Standards refresh, which became effective in January 2018 — the same year Apple celebrated the 10th anniversary of the iPhone. That refresh incorporated WCAG 2.0 Level AA (published in 2008) as the baseline for web content.
The web has changed dramatically since then. What agencies are legally required to meet today is built on a standard from 2008 — the same era as the original iPhone. Agencies should treat WCAG 2.0 AA as the floor, not the ceiling.
Legal Requirement
WCAG 2.0 Level AA (published 2008)
Referenced by the Section 508 ICT Standards refresh (effective 2018). Agencies must meet these 38 success criteria to satisfy their Section 508 obligations for web content.
- Text alternatives for non-text content
- Captions and audio descriptions for multimedia
- Keyboard accessibility and focus management
- Minimum color contrast (4.5:1 for normal text)
- No seizure-inducing content
- Consistent navigation and labeling
- Error identification and correction
Best Practices
WCAG 2.1 and 2.2 Level AA (published 2018 and 2023)
These later versions add criteria that reflect how the web actually works today — mobile devices, cognitive accessibility, and modern authentication patterns — and are strongly recommended for any agency aiming to serve all Americans. The US Federal Government is one of the last to use the legacy WCAG 2.0 AA Standard, as it was developed ~2 decades ago.
- WCAG 2.1 (2018): 17 new criteria for mobile, low vision, and cognitive accessibility
- WCAG 2.2 (2023): 9 more criteria for authentication and cognitive tasks, removing the outdated "Parsing" criterion
- W3C now recommends WCAG 2.2 as the current normative standard for new and updated content
The scores and findings in this report are based on automated checks aligned with WCAG 2.x rules surfaced by axe-core. Passing automated checks is necessary but not sufficient: manual testing with assistive technologies is required to verify true conformance and to catch barriers that automation cannot detect.
Take Action
Today's scan identified 209 accessibility barriers across the most-visited U.S. government websites, affecting an estimated ~4,000,000 Americans with disabilities. Here is how you can help.
- Read the federal accessibility report. The 2025 Governmentwide Section 508 Assessment from the GSA Administrator details the state of federal accessibility compliance and the steps agencies are taking to improve.
- Submit URLs you care about. Want specific government pages included in future scans? Submit them to the Open Scans project to help broaden coverage.
- Test with free tools. Do your own automated and manual accessibility testing with Accessibility Insights and Google Lighthouse. Automated tools catch a significant portion of WCAG failures quickly; manual review with assistive technologies catches the rest.
- Adopt and update the U.S. Web Design System (USWDS). The USWDS is already a strong foundation for accessible, consistent federal websites, but many agencies have not adopted it or are running outdated versions. Encourage your agency to adopt or upgrade so every American benefits from its accessibility work.
- Hire people with disabilities. People with disabilities are the ultimate experts on digital barriers. Bringing them into design, engineering, and testing teams — not just as consultants but as full-time employees — leads to more accessible products and services for everyone.
