Accessibility Atlas

42 datasets covering disability demographics, employment gaps, web accessibility compliance, assistive technology patents, special education, healthcare, housing discrimination, transportation, government benefits, and more -- across 15 categories.

Built for researchers, journalists, policy analysts, and anyone building tools for disabled communities.

What's Inside

US Disability Demographics (Census Bureau)

8 datasets from the American Community Survey covering county, state, and national disability rates.

• County-level: 3,100+ counties (ACS 5-Year 2022)
• State-level: 50 states + DC (ACS 5-Year 2021)
• National trends: 13-year trend (11.9% to 13.6%)
• Demographics: by race, age, sex, and 6 disability types

Disability Employment

4 datasets on the employment gap, discrimination charges, and workplace accommodations.

• BLS employment/unemployment by disability status
• FRED 16-year time series (gap narrowing from 40pp to 37pp)
• 679,637 ADA discrimination charges (1992-2024)
• JAN accommodation cost data (58.7% cost $0)

Special Education (IDEA)

6 datasets from the National Center for Education Statistics on 7.5M students served under IDEA Part B.

• 13 disability categories
• 51 states
• 1976-2023 historical data
• Demographics, environments, state-level breakdowns

Web Accessibility

5 datasets on WCAG compliance, lawsuits, screen reader usage, and Section 508.

• WebAIM Million: 94.8% of top 1M pages fail WCAG
• Screen reader survey: 1,539 respondents
• ADA digital lawsuits: 814 (2017) to ~4,000 (2024)
• Section 508: 245 federal entities, only 23% conform
• HTTP Archive a11y trends 2019-2024

International Disability

8 datasets covering 194+ countries.

• WHO: disability prevalence, DALYs/YLDs, healthy life expectancy
• OECD: 34 countries, prevalence/employment/spending
• Eurostat: 36 EU countries
• World Bank: 10 socioeconomic indicators
• UN CRPD: 199 countries ratification status

Government Benefits

• SSA: SSDI/SSI annual data (7.3M + 4.9M beneficiaries)
• VA: disability compensation by state (5.7M+ veterans)

Healthcare & Mental Health

• CMS: Medicaid disability enrollment (10.2M enrollees)
• SAMHSA: mental health prevalence 2008-2023

Housing, Transportation, Education

• HUD: fair housing complaints (disability is #1 basis, ~55%)
• NTD: paratransit ridership/costs ($40-50/trip)
• CRDC: Section 504, restraint/seclusion, discipline

Assistive Technology Patents

• WIPO: patent data 1985-2026 (10 → 519 patents)

Visual Accessibility

• VizWiz: 4,319 VQA pairs from blind users (CC BY 4.0)

Key Findings

44.1 million Americans (13.4%) have a disability (Census 2022). Rate rose from 11.9% (2010) to 13.6% (2023). Ambulatory (6.7%) and cognitive (5.7%) are most common.

The employment gap is massive. 24.5% labor force participation (disabled) vs ~67% (non-disabled). OECD average gap: 34 percentage points.

Workplace accommodations are cheap. 58.7% cost nothing. Median: $300. Yet 679,637 ADA charges filed since 1992.

The web is still broken. 94.8% of top 1M websites fail WCAG. Average: 51 errors/page.

Disability is #1 basis for fair housing complaints (~55% of all HUD complaints).

Special education is growing. 15.2% of public school students now served under IDEA. Autism grew 8.5x since 2000.

Globally, 1.3 billion people (16%) live with significant disability (WHO). 190 countries signed UN CRPD.

Notebooks

10 Jupyter notebooks in notebooks/ that load the data, run analysis, and produce charts:

• census_disability_demographics.ipynb: Maps, trends, demographic breakdowns
• disability_employment.ipynb: Employment gap over time, discrimination charges
• web_accessibility.ipynb: WCAG failure trends, screen reader market share
• international_disability.ipynb: Cross-country comparisons
• special_education_idea.ipynb: Enrollment trends, discipline disparities
• government_benefits.ipynb: Benefit trends, state-level processing
• healthcare_mental_health.ipynb: Enrollment, treatment gaps
• housing_transportation_education.ipynb: Fair housing, transit costs
• assistive_technology.ipynb: Patent growth by category
• sign_language_vision_aac.ipynb: Visual question answering

Plus accessibility_atlas_demo.ipynb in root as a quick-start sampler.

About

Part of the Data Trove collection. I built this because disability data is scattered across dozens of federal agencies, international organizations, and advocacy groups. Having it all in one place -- with consistent formatting and analysis notebooks -- makes it actually usable.
