For all persons, INCSSI reports the total income they received from Supplemental Security Income (SSI). Using the reported income information, annual income amounts were then edited and imputed for every record on the full-year file. Please refer to the IPUMS user note on Income Data in MEPS for more information on the collection, editing (including top- and bottom-coding), and imputation of income variables in MEPS, as well as changes to the target population for income data collection over time. Users may also be interested in the data quality flag, QINCSSI, which reports the editing methods used for INCSSI.
If respondents needed more information about what kinds of income to report as SSI income, they were provided with the additional definition: "This federal program provides monthly cash payments in accordance with uniform, nationwide eligibility requirements to persons of all ages who are blind, disabled, or both needy and 65 years or older."
Users may wish to note that IPUMS defines the universe for this variable as all persons because of the family-style question associated with this income source. Family-style questions ask the family respondent if anyone in the family received income from this source. In addition to the opportunity to report SSI income via the family-style question, all persons in the household were eligible to list additional income from "other" sources, which includes income from sources previously asked about in the survey.
INCSSI is an 8-digit numeric variable with 2 implied decimals. That is, values of 01234567 should be interpreted as 12345.67. The command files delivered with IPUMS extracts automatically divide INCSSI by 100, so no further adjustment is needed.

For more information on how income data were collected by MEPS and changes to the imputation methods for these questions over time, please see the IPUMS user note on Income Data in MEPS.
Beginning to 1999, persons could only report income in full dollar amounts. Prior to 1999, persons could report income in dollars and cents.
