How is "Disability" defined in the context of Social Security?

The definition of "Disability" in the context of Social Security is centered around the inability to engage in substantial gainful activity due to a medically determinable impairment. This means that for an individual to qualify for Social Security Disability Insurance, their condition must not only prevent them from performing their previous work but must also limit their ability to engage in any significant gainful activity.

A medically determinable impairment refers to a condition that can be verified through medically acceptable clinical and laboratory techniques. It emphasizes the need for objective medical evidence. Simply having an impairment is not sufficient; it must be significant enough to inhibit the individual from earning a living.

The focus on substantial activity distinguishes disability from temporary conditions or minor impairments that may not significantly impact a person's ability to work. This aligns with the overall purpose of Social Security Disability Insurance, which is designed to support those who are genuinely unable to participate in the workforce due to long-term health issues.
