Tonga: Control of Corruption - Governance score

39.63ordinal scale (0-100) · 2025+9.5% since 2015

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 score is a linear transformation of the governance estimate using hypothetical worst-case and base-case countries. It is an absolute score ranging from 0-100. Larger values correspond to better governance. The (country-series-time) metadata include the (a) number of sources, and (b) confidence intervals (lower and upper bound). The number of sources indicates the number of underlying data sources on which the governance score (respectively the underlying governance estimate) is based. The confidence intervals include the lower and upper bound of the 90% confidence interval for the governance score. Confidence intervals are a statistical range of values that likely contain the true value (of what is being estimated). Annual figures for Tonga from 2004 to 2025.
