SSI awardees who first received SSI payments prior to their 18th birthdays are not included in the sample cohort.

NOTE: Sample comprises SSI awardees who were aged 18–64 at award in 2000. Sample is limited to first-time awardees who were not DI beneficiaries before or within 72 months after SSI award; for a given cross-section, the sample is further limited to survivors aged younger than 65. SSI awardees who were first entitled to SSI payments prior to their 18th birthdays are not included in the sample cohort.

A value of zero Medicaid expenditures is imputed for individuals who did not have Medicaid coverage in all 12 months of a given year.
Because Medicaid expenditures are heavily skewed toward the upper tail, expenditures in the 1st decile are equal or close to zero.
Rounded components of percentage distributions do not necessarily sum to 100.
