Supplemental Security Income (SSI) benefits

The federal Supplemental Security Income (SSI) program provides monthly payments to people who are blind, disabled, or age 65 or older with limited income and resources who meet eligibility criteria; blind or disabled children may also qualify. Federal benefits can be supplemented with state contributions; benefits vary by state and by recipient. Federal benefit maximums change yearly. In 2018 federal monthly maximums were $750 for an individual and $1,125 for a couple (SSA-SSI), with average benefits of $662 for children, $577 for adults, and $447 for elderly beneficiaries (SSA-Snapshot 2018). SSI incentivizes work by disregarding $1 out of every $2 earned over $65 for benefit calculation. Personal assets help determine eligibility; individuals cannot have countable resources above $2,000, and couples are limited to $3,000. Child recipients are assessed at age 18 to determine eligibility under adult standards (SSA-SSI). In most states, individuals eligible for SSI are eligible for Medicaid, and in 32 states and Washington DC Medicaid is automatically conferred (SSA-Medicaid).

Evidence of Effectiveness

Increasing Supplemental Security Income (SSI) benefit levels is a suggested strategy to reduce poverty among senior citizens aged 65 and older, and adults and children who are blind or have severe disabilities (CBPP-SSI 2014). Available analysis indicates SSI brings some recipients and their families above the poverty line (SSA-Stegman Bailey 2015). Benefits raise half of child beneficiaries out of poverty, and bring some of the poorest recipients above 50% of the poverty line (CBPP-Romig 2017). However, at current benefit levels, SSI may not alleviate material hardship (Ghosh 2015) or food insecurity for families with children with disabilities ().

Loss of SSI benefits has been shown to increase the likelihood of unmet medical needs () and hardships such as hunger and homelessness (). A study of child SSI recipients who underwent redetermination in 1998-2006 as they aged out of the program suggests that recipients who lose benefits at age 18 have higher rates of employment at age 24 than those who continue to receive SSI; on average, employment rates are close to those of peers with disabilities but substantially lower than those without disabilities (). However, health outcomes and ability to live independently have not been assessed (Mathematica-Levere 2017). While some youth secure full-time, full-year employment, overall earnings among former recipients average $4,400 annually and income volatility is substantial (Deshpande 2016). 

Higher SSI benefit rates may decrease disability among the elderly (Herd 2008). Experts suggest many children with mental disorders who may meet eligibility criteria for SSI are not receiving benefits (). Additional evidence is needed to confirm optimal program targeting and benefit amounts for children and adults.

Implementation Examples

As of December 2017, over 8 million individuals received Supplemental Security Income (SSI). SSI provides support for 1.1 million US children (SSA-SSI 2018), about half of them eligible because of disability due to a mental disorder (). State policies regarding enrollment of children with mental disabilities (), and practices regarding cessation and continuation for children older than 18 vary widely ().

Approximately 4 in 9 SSI recipients receive a state supplement to their federal benefits. Four states do not offer SSI supplements for adults: Arizona, Mississippi, North Dakota, and West Virginia. Eighteen states do not provide a state supplement for children. The federal Social Security Administration implements SSI supplements for eleven states and Washington DC; other states implement their own programs (SSA-SSI).
