Research Archive on Disability in the U.S. (RADIUS)

The RADIUS archive is a collection of 19 studies comprised of over 25,000 variables and over 1.5 million (unweighted) cases that address the topic of disability. These data sets permit analyses on topics such as:

• the incidence and prevalence of specific diseases, disorders, and impairments, including deficits of cognition, emotion, physiology, and anatomical structure;
• functional limitations across a variety of specific organ systems;
• disabilities in relation to major life roles and activities, such as work, parenting, education, and recreation;
• societal limitations including physical, attitudinal, and economical barriers that restrict full participation in society;
• psychosocial and interpersonal factors such as coping with stress, sexuality, feelings of control and productivity, quality of life, and family relations and support;
• health care and rehabilitation issues such as medical costs, coverage, service utilization, use of orthotic, prosthetic, assistive devices, effectiveness of rehabilitation.

The purpose of the project is to facilitate access to the best data sets on the prevalence, incidence, correlates, and consequences of disability in the U.S.
