Meseguer 2021 — DI Beneficiary Mortality vs. General Population

Summary

A synthesis of nine Social Security Administration (SSA) actuarial studies covering disability insurance (DI) disabled-worker mortality from the 1970s through 2015. Compares DI beneficiary period mortality and life expectancy against the general population across age, sex, and duration on the rolls. Embeds the mortality data in a detailed chronology of legislative, epidemiological, and administrative events that shaped the DI beneficiary pool over time.

Key Claims

• DI beneficiaries in their first year on the rolls (ages 25+) had higher mortality than the general public during the 1918 influenza pandemic, in every study period through 2015.
• At age 50 in 2011–2015, DI beneficiary mortality was 8.5× (men) and 9.9× (women) higher than the general population; life expectancy was ~10 years shorter.
• Mortality is highest in year 0 of entitlement and declines with each subsequent year survived; after 10+ years on the rolls, mortality still exceeds the general population by 4–5×.
• DI beneficiary mortality improved faster than the general population's from 1977–2015, particularly at zero duration and for younger ages.
• The gender-age paradox: female beneficiaries have lower absolute mortality than males but higher relative mortality vs. their general-population peers; young beneficiaries (25–35) face the highest relative mortality ratios (up to 70×).
• The vocational grid (SSA age thresholds at 50 and 55) produces visible dips in the DI mortality curve that have grown more pronounced over time.
• A $1,000/year increase in DI benefits reduces annual mortality by ~0.26 percentage points (Gelber, Moore, Strand 2018 cited).

Quotes

"DI beneficiaries aged 25 and older in their first year on the rolls have faced mortality rates far exceeding those associated with the 1918 influenza pandemic for the general public at those ages."

"After surviving on the DI rolls for a decade or more, mortality at age 50 in 2011–2015 was 3.9 times higher for men and 4.5 times higher for women than for their counterparts in the general population."

My Take

The paper's main contribution is the chronological framing: mortality statistics alone are uninterpretable without understanding who was entering the rolls and why in each era. The 1991–1995 AIDS spike and the 1997 highly active antiretroviral therapy (HAART) inflection are the clearest natural experiments. The vocational grid mortality dips are a striking and underappreciated finding — administrative policy leaves a legible signature in mortality curves.
