What impacts the benefits receivable under social security disability insurance?

The benefits receivable under Social Security Disability Insurance (SSDI) can be influenced by other income sources, which is why this is the correct choice. SSDI is designed to provide financial assistance to individuals who are unable to work due to a qualifying disability, and the amount a beneficiary receives can be affected by various income streams they have. Specifically, if an individual receives income from other sources, such as private disability insurance or other governmental assistance, it may reduce the SSDI benefits they are eligible for, due to the offset rules in place.

While employment history is important for determining eligibility, as it establishes a work record and earnings needed for SSDI qualification, it does not directly impact the monthly benefits amount like other income does. Similarly, age at application matters in terms of eligibility rules but isn't a determining factor for the benefit amount. Gender does not affect the benefits calculation or amount in any significant way in the context of SSDI. Thus, the presence of other income sources stands out as a critical factor that can adjust the benefits paid to an individual under Social Security Disability Insurance.
