Data

What sits behind the headline figures.

MilitarySpend combines public military expenditure datasets with explicit approximation logic so readers can see both the number and the boundary around it.

Primary baseline

The flagship global tracker uses SIPRI military expenditure data as the baseline source. SIPRI remains the most widely used public reference for cross-country military spending comparisons, which makes it the cleanest starting point for the publication's general-purpose tracker.

  • Baseline year: 2025
  • Display year: 2026
  • Scope: 30+ countries in the public database
  • Homepage counter: the top six military spenders in the live visualization

Calculation model

The live counter converts annual spending into a per-second approximation and accumulates that value from January 1 of the current year. It is a scale visualization, not a literal ledger of disbursements.

Per-second spending = annual budget ÷ 31,536,000

Counter total = elapsed seconds × combined per-second rate

Baseline datasets

The core tracker uses SIPRI military expenditure data as the baseline for cross-country comparison. That gives the site a stable reference point before any modeling or presentation layers are added.

Document-level checks

When a story requires more than a baseline table, we check official budgets, budget amendments, parliamentary material, annual reports, and other primary records that can tighten the estimate or explain the change.

Fast-turn estimates

For topical conflict analysis and briefings, public estimates and named institutional analyses may be used when the underlying accounting is still moving. Those figures are treated as provisional unless better records are available.

Revision trail

If a source is superseded, clarified, or corrected, the publication updates the relevant page and keeps the methodological note aligned with the newer public record.

How to read the figures

Annual values are normalized for readability. They are not presented as a claim that military spending clears the treasury on a literal second-by-second basis.

Exchange-rate movement, inflation treatment, and off-budget activity can all change the meaning of a headline number. We flag those differences instead of flattening them away.

The homepage counter is a visualization of scale. The data page is the place to understand what is being measured, projected, and held constant.
