inaccessibility

Inaccessibility is the state in which people cannot reach, perceive, understand, or use a place, service, information, or opportunity due to barriers. It can be physical, digital, sensory, cognitive, or social in nature and may be temporary or permanent.

Common domains of inaccessibility include the built environment (stairs without ramps, narrow doorways), transportation (services that do not accommodate mobility aids), digital spaces (websites or apps without keyboard navigation, screen-reader compatibility, or captions), and information or services presented in complex language or lacking reasonable accommodations. Inaccessibility can also arise from economic, linguistic, or cultural barriers that prevent full participation in society.

Causes of inaccessibility include design choices that exclude certain users, insufficient or poorly enforced policies, budget constraints, lack of awareness or involvement of affected groups, and discriminatory practices. The consequences range from limited access to education, employment, and healthcare to reduced civic participation and safety risks. Inaccessible environments can also impose higher costs on individuals and communities over time.

Measurement and remedies focus on identifying barriers and implementing solutions. Methods include accessibility audits, user testing with diverse groups, and compliance with standards such as digital accessibility guidelines, architectural codes, and anti-discrimination laws. Approaches like universal design, accessible procurement, accommodations, and ongoing maintenance are common strategies. International and national frameworks emphasize equal access as a fundamental aspect of rights and inclusion, guiding efforts to reduce inaccessibility across domains.
