Federal Data on Disabilities

CDC estimates that one in 4 U.S. adults – 61 million Americans – have a disability that impacts major life activities, according to a report in CDC’s Morbidity & Mortality Weekly Report 2018;67:882–887. DOI: http://dx.doi.org/10.15585/mmwr.mm6732a3  The most common disability type, mobility, affects 1 in 7 adults. With age, disability becomes more common, affecting about 2 in 5 adults age 65 and older.

What are assistive technologies?

What are assistive technologies and why are they important?

  • screen magnifiers, and other visual reading assistants, which are used by people with visual, perceptual and physical print disabilities to change text font, size, spacing, color, synchronization with speech, etc. in order to improve the visual readability of rendered text and images

  • screen readers, which are used by people who are blind to read textual information through synthesized speech or braille;

  • text-to-speech software, which is used by some people with cognitive, language, and learning disabilities to convert text into synthetic speech

  • speech recognition software, which may be used by people who have some physical disabilities

  • alternative keyboards, which are used by people with certain physical disabilities to simulate the keyboard (including alternate keyboards that use head pointers, single switches, sip/puff and other special input devices)

  • alternative pointing devices, which are used by people with certain physical disabilities to simulate mouse pointing and button activations
