People with a disability, ages 16-64 years, are more likely to receive means-tested income (primarily from SSI) and less likely to receive earned income or asset income (e.g. from investments), compared to people with no disability. Among working-age people with a disability, 16.5% receive Social Security disability or retirement income, and this number rises to 30.3% for people with a severe disability. In the category of means-tested income, 10.6% of people with a disability and 22.3% of people with a severe disability receive SSI.
Given the lower employment rates of people with disabilities, it is not surprising that people with a disability are less likely to receive wage or salary income. Only 42.9% of people with a disability had any income from a first or primary job, compared to 66.4% of people with no disability. In terms of average monthly income from a primary job, people with a disability earned nearly 57% less ($779 per month for people with a disability, compared to $1368 for people with no disability).
