Definition
Disability refers to any restriction or lack of ability (resulting from an impairment) to perform an activity in the manner or within the range considered normal for a human being. Impairments associated with disabilities may be physical, mental, or sensory motor impairment such as partial or total blindness and deafness, muteness, speech defect, orthopedic handicaps, and mental retardation. Data on disability will enable planners to prepare plans for rehabilitation, education development and preventive programs.
