Spendable-dollar variant

The headline counts healthcare at total cost — including the employer-paid share of the insurance premium (national-accounts-consistent). Counting only what a household pays from its own pocket, the Income — Fourth Quintile annual rate is 3.10%/yr vs 3.48%/yr standard. Same price series, healthcare re-weighted — see the methodology, or query ?basket=spendable on the API.

Per-stratum decomposition

Each contribution is the stratum's weight × its long-run rate over its coverage window. They reconcile to the headline annual rate via a chain-link & coverage residual (the index is chain-linked at composition boundaries and some strata cover only part of the window) — shown in the table footer.
