Methods: This paper has two aims. First, I estimate SSI take-up rates by age and test whether discontinuities in SSI take-up exist when SSA disability determination rules are relaxed (at ages 45, 50, 55, and 60) and eliminated (at age 65). Second, I identify patterns of employment, homelessness, and public assistance use among SSI recipients in the five years prior to SSI take-up and examine how these patterns vary by age. I conduct these analyses with administrative microdata from multiple agencies in Washington state spanning from 2010 through 2017.
Results: This research yields three key findings: First, I find significant and discontinuous increases in SSI take-up at age 55 and age 65. Second, I find that people who first received SSI between the ages of 40 and 59 were more likely to have experienced homelessness in the five years prior to SSI take-up than to have been employed. This gap is concentrated among people who first received SSI before age 60: nearly half of this group had experienced at least one quarter of homelessness, but only about one-third were employed for at least one quarter. Third, I find that most eventual SSI recipients participated in public assistance programs in the five years prior to receiving SSI, regardless of their age at SSI take-up.
Conclusions and Implications: The significant discontinuous increase in SSI take-up at age 55 following the relaxation of disability rules in the medical-vocational grid suggests that the age threshold may be arbitrarily delaying otherwise-eligible people from receiving SSI benefits. The low employment rate among eventual SSI recipients is contrary to the assumptions built into the SSA disability determination process, but consistent with expectations for the SSI population who by definition have little work history. The low employment and high homelessness rates raise questions about how people make ends meet in the five years before they start receiving SSI.
