How much does the world spend on healthcare per person?

Healthcare expenditure per capita · $/person/yr · measured 2000–2023 · fitted live from 24 observations by the Many Minded cost-curve engine.

The last measured value is $1891 (2023, OWID / WHO). Over the fitted window the series rises 5.0% a year (80% interval +4.2% to +5.9%) — a doubling every 14.1 years (80%: 12.1–16.9). Carried forward on that fit, 2028: $2418 (80%: $2253–$2594).

Last measured 2023. The source has not published a newer figure we have verified, so the 3 years since are projections too, not observations.

Vertical axis: $/person/yr, log scale. Solid: measured observations. Dashed: the fitted central projection. Shaded: the 80% interval, which widens with horizon because shocks accumulate.

what this series measures

world per-capita healthcare expenditure — the care COUNTER-curve: the one great cost still rising; the care gate stays editorial until this line bends.

Not shown for this curve, because the machinery returns nothing: Wright's law (no cumulative-deployment series for this technology); a regime break (none clears the sup-F threshold).

the projection, with its interval

Log cost as a random walk with drift: the forecast variance grows with horizon (τ + τ²/m), which is why these bands widen instead of staying parallel. The middle column is the least useful number on this page; the interval is the claim.

questions this page answers

How much does the world spend on healthcare per person?

$1891 as of 2023, the latest measured value in the series (OWID / WHO). The fitted trend has it rising 5.0% a year, with an 80% interval of +4.2% to +5.9%.

How fast is healthcare spending per person rising?

+5.0% a year over the fitted window, an 80% interval of +4.2% to +5.9% — a doubling every 14.1 years (80%: 12.1 to 16.9 years). Fitted from 11 observations spanning 10 years.

What will healthcare spending per person be in 2028?

The central fit says $2418, inside an 80% interval of $2253 to $2594. The interval is the forecast; the middle number is only its midpoint. Bands widen with horizon because shocks accumulate — a constant-width band would be overconfident.

Is the rise in healthcare spending per person accelerating or slowing?

Splitting the record in half, the fitted rate went from 6% to 5% a year — steady. Regime breaks, not window choice, are what dominate this method's errors — which is why every projection here carries an interval.

Where does this data come from?

OWID / WHO. 24 observations spanning 2000–2023. Curated benchmark history, extended by a weekly authoritative fetch and by news figures fact-checked against their source before they may touch a fit. Both the observation ledger and the fitting code are public, and the engine publishes its own calibration score and its misses.
