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)

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.

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.
