Which legislation authorizes Social Security Disability Insurance (SSDI)?

The legislation that authorizes Social Security Disability Insurance (SSDI) is Title 2 of the Social Security Act. This title specifically establishes the framework for the Social Security program, including provisions for disability insurance. It outlines eligibility criteria, the benefits provided, and how the program is administered. Title 2 is integral to the Social Security Administration's ability to provide financial assistance to individuals who are unable to work due to a disability, ensuring that those who have paid into the system through Social Security taxes can receive benefits when they qualify.

The other options refer to different sections of various acts that do not directly relate to SSDI. For instance, Section 202 pertains to different facets of the Social Security program but does not exclusively authorize SSDI. Title 3 of the Disability Act and Section 201 of the Labor Act are not components of the Social Security framework concerning disability insurance, thus reinforcing that Title 2 is the correct legislative authority for SSDI.
