Solomon Islands: Control of Corruption - Governance estimate (approx. -2.5 to +2.5)

Key figures

What the numbers say

In 2025, Solomon Islands' control of Corruption - Governance estimate (approx. -2.5 to +2.5) fell 0.02 on 2024 (from -0.14 to -0.16).

Across the 22 yearly changes before that (2003 to 2024), the average change was −0.00321 and a typical year strayed about 0.11 from that (the standard deviation). This year's change was 0.1 standard deviations below that average, so it was an ordinary year: it sits within the range of normal year-to-year movement.

On record, the biggest yearly rise was 0.26 in 2017 and the biggest yearly fall was 0.24 in 2006. The numbers show how large and when, not why; for the cause, look at what happened in that country in those years.

From 2016 to 2025 there is no clear straight-line trend: a straight line explains 7% of the movement over 10 observed years, so the value is moving around more than it is heading anywhere.

What this measures

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.

Limitations: The WGI are perception-based measures which draw on 35 distinct underlying data sources, namely expert assessments and household/firm surveys. Data sources based on expert assessments have both strengths and limitations relative to surveys. A key strength is that they are well suited to cross-country comparison, since their methodologies are explicitly designed for this purpose. Expert assessments can also provide more detailed technical judgments on specific public institutions or governance functions that typical household or firm survey respondents may not be well placed to assess.

Regional and income-group figures are computed by the World Bank as a indicators, from the underlying data sources, are aggregated using the unobserved components model (ucm). the ucm is essentially a weighted average, resulting in a governance estimate at the country level. the following provides a detailed description of the aggregation methodology: https://www.worldbank.org/content/dam/sites/govindicators/doc/the%20worldwide%20governance%20indicators%202025%.
