1983: the year Social Security checks did not rise
Every other year from 1975 to 2026 has a cost-of-living adjustment page on this site. 1983 does not, because no COLA was payable during it — and that is a fact about the statute, not a gap in the data.
Cost-of-living adjustment payable during 1983
None
The 1983 Amendments moved the adjustment from June to December, and the June 1983 increase was the one that got moved.
What happened
Through 1982, a cost-of-living adjustment took effect with benefits payable for June, so a beneficiary saw it in the July check of the same year. The Social Security Amendments of 1983 — Public Law 98-21 — shifted the adjustment to December, first paid the following January. The change was made in the year the adjustment would otherwise have landed in June.
The consequence is arithmetic rather than interpretation. The increase determined in 1983 became effective with December 1983 benefits, which are paid in January 1984. No increase reached a check between the July 1982 payment and the January 1984 payment. A full calendar year passed at the same rate.
Why this page exists at all
SSA’s published table indexes each adjustment by the year it was determined. The public, the press and SSA’s own fact sheets name each one by the year it reaches a check. Those two conventions agree for 1975 through 1982 and disagree by one year from 1984 onward — and 1983 is the seam where the mapping changes. A naive “add one year” rule produces a 1983 page that never existed. The full year-label problem is set out here.
What SSI recipients received instead
The same law that delayed the adjustment granted a flat statutory increase to the SSI federal benefit rate from July 1983: $20.00 a month for an individual and $30.00 a month for a couple. SSA’s SSI table labels the change 7.0%, which reads like a cost-of-living adjustment and is not one — it is a dollar amount written into P.L. 98-21 (Social Security Amendments of 1983), and the arithmetic confirms it exactly.
| SSI federal benefit rate | Before | Statutory increase | From July 1983 |
|---|---|---|---|
| Individual | $284.30 | $20.00 | $304.30 |
| Couple | $426.40 | $30.00 | $456.40 |
A percentage adjustment applied to $284.30 would have to land on exactly $20.00 and on exactly $30.00 at the couple rate for the same percentage to be doing the work. It cannot: the two increases are different fractions of their bases. A flat dollar amount is the only rule that produces both numbers.
The two years either side
- The 1982 COLA
The last adjustment of the June era — paid with benefits for June 1982.
- The 1984 COLA
The first adjustment of the December era — determined in 1983, first reaching a check in January 1984.

The Social Security Amendments of 1983 (P.L. 98-21) delayed the June 1983 COLA to December 1983. Checks never rose during calendar 1983, and the 3.5% at SSA table row 1983 is the "1984 COLA".
