The International Data Sovereignty Index — Edition 0 (2026)

How the world stands on data sovereignty in 2026.

194 States surveyed against thirty-one sub-indicators across five pillars derived from the Charter. A non-ranking instrument, by design — and the most comprehensive picture of the data-sovereignty landscape published to date.

Headline coverage

Edition 0 surveys all 194 States.

Edition 0 is issued from open-source data alone, prior to the first Charter signing cycle. It is presented as a recruitment instrument rather than a report card. Per-State entries are published for Tiers A, B, and C, with composite scores for Tiers A and B and pillar scores for Tier C.

Tier A54Full preliminary score possible — 24 or more sub-indicators scorable from open sources.
Tier B74Defensible preliminary score possible — 18 to 23 sub-indicators scorable.
Tier C27Partial coverage — 10 to 17 sub-indicators. Pillar scores reported, no composite.
Tier D37Insufficient open-source coverage in this Edition. State is listed and invited to engage.

Tiers A and B together — the 128 States carrying a composite score in Edition 0 — match the Custodian's pre-edition estimate of approximately 125 States set out in the Preliminary Coverage Assessment (May 2026), reproduced at Annex C of Edition 0.

Methodology in brief

Five pillars, thirty-one sub-indicators, one composite.

Pillars are weighted equally at twenty percent each. Each sub-indicator is scored on a 0–10 rubric. The pillar score is the unweighted mean of its sub-indicators; the composite is the weighted mean of the five pillar scores expressed on a 0–100 scale.

Global pillar averages (0–10 scale, all 194 States)

Pillar V — Ecosystem & Education5.51
Pillar II — Technical Safeguards5.17
Pillar I — Legal Foundation5.00
Pillar III — Universal Identifier4.14
Pillar IV — Sovereign Haven3.38

Pillar IV — Sovereign Haven Infrastructure — sits notably below the other four. Pillar V — Ecosystem, Education, and Implementation — leads.

The reports

Four publications. One coherent picture.

Edition 0 is the foundational survey. Supplement A tests the relationship between physical investment and legal-constitutional infrastructure across the world's top 100 data-center markets. Supplement B publishes explicit ranking tables — by composite, by pillar, and by region. Supplement C re-runs the Supplement A analysis with the United States excluded, to test outlier sensitivity and surface what the global picture looks like in the community ex-US.
