How the Social Security Administration Defines Disability

For all individuals applying for disability benefits under Title II, and for adults applying under title XVI, the definition of disability is the same. The law defines disability as:

The inability to engage in any substantial gainful activity (SGA) by reason of any medically determinable physical or mental impairment(s) which can be expected to result in death or which has lasted or can be expected to last for a continuous period of not less than 12 months.
