Control of corruption
estimate, roughly −2.5 to +2.5
- Published value. Native scale: standard-normal units, roughly −2.5 (worst) to +2.5 (best), world mean 0.
- Transform: value (no transform).
- Goalposts (fixed for all years; 2.5th and 97.5th percentiles of all observed country-years): worst = -1.54 scores 0, best = 2.11 scores 100.
- Direction: higher is better, no flip.
- Clip and scale: anything below the worst goalpost scores 0 and anything above the best scores 100; multiply by 100.
Where the numbers come from
- Worldwide Governance Indicators (World Bank), 2025 revision produces the series — Aggregates about 30 underlying data sources (household and firm surveys, NGO assessments, commercial risk raters, public-sector bodies) into one estimate per country-year with an unobserved-components model; the site shows which sources enter each country's estimate.

Control of Corruption (CC) captures perceptions of the extent to which public power is used for private gain, including both petty and grand corruption, as well as capture of the state by elites and private interests. Governance estimate from the aggregation model, in units of a standard normal distribution, i.e. ranging from approximately -2.5 to 2.5. Larger values correspond to better governance. The (country-series-time) metadata include the (a) number of sources, and (b) standard error. The number of sources indicates the number of underlying data sources on which the governance estimate is based. The standard error indicates the precision of the governance estimate. Larger values indicate less precise estimates. A 90% confidence interval for the governance estimate is given by the estimate +/- 1.64 times the standard error.
Every country row below has a “verify” link to this series filtered to that country, so each value can be checked against the source.
