Sources and data coverage
World: what is connected, from where and for which period; what is not connected and why. Every published indicator keeps its source, period, territory, unit and transformation version. Dataset version: world-2026-10-19.

What limits the data
- The observation year differs between countries; outdated values are flagged under the indicator's policy and not hidden.
- WGI indexes are aggregate perception scores, not measurements. Form of government, regime type, legal guarantees and survey indicators are separate indicators and are not connected yet.
- Countries with no value for an indicator are unknown for it: that is not zero.
