Children's Supplemental Security Income (SSI) is for children under 18 who are disabled. SSI is a public assistance program, and there are strict income and resource requirements that can reduce or eliminate an individual's eligibility.
Disabled Adult Child's Benefits (often referred to as CDB or Childhood Disability Benefits) are available to unmarried individuals who became disabled before age 22, and who have at least one parent who is receiving SSD; who is receiving Social Security Retirement (SSR) benefits; or who is deceased and had been eligible to receive SSD or SSR benefits. Payments are based on the earnings record of the parent.
