The problem of physical disability is growing as modern technology rises due to a combination of increased injury rates and improved medical techniques, resulting in a rapidly growing number of surviving disabled persons. Despite the increasing incidence of disability, unnecessary physical barriers which exist throughout our society prevent four-fifths of all employable disabled adults from earning a living. This report covers the four areas where environmental barriers are most serious: housing, public facilities, transportation, and recreation. Federal, state, and local programs to eliminate barriers, and future areas of emphasis in reducing barriers to mobility are considered.
