Accessibility impacts huge numbers of people worldwide and shows up across everyday digital services. On this page, we’ll connect the statistics on disability prevalence with the barriers users face—like keyboard access, screen reader support, low contrast, and missing alt text. You’ll also see what those failures mean for real outcomes such as slower task performance, conversion lift, and compliance risk for organizations.
