Accessibility for All

The US Census Bureau states that, in 2010, approximately 56.7 million people (18.7%) of the US population had a disability of some kind, and about 38.3 million (12.6%) had a severe disability. The United Nations’ World Report on Disability states that, worldwide, more than one billion people live with some form of disability, of whom nearly 200 million experience considerable difficulties in functioning on a daily basis.


Web accessibility to all people, regardless of disability type or severity of impairment. The term "accessibility" is most often used in reference to specialized hardware or software, or a combination of both, designed to enable use of a computer by a person with a disability or impairment.
