4 sub-national regions - 1995-2022. Latest country-level SCI: 41.2 (2022).
The most corrupt region of Congo Brazzaville is Brazzaville (37.7/100), and the least corrupt is South (46.3/100), on a 0-100 scale where 0 is most corrupt and 100 is least. All 4 regions are ranked below.
The Subnational Corruption Index is scored 0–100 on the same orientation as Transparency International's Corruption Perceptions Index (higher = cleaner). The difference: the CPI and the World Bank measure the perceptions of experts and business executives and report one national number, while the SCI is built from what ordinary households perceive and experience — and it breaks Congo Brazzaville into 4 regions.
| Index | Latest | Scale | Based on |
|---|---|---|---|
| Subnational Corruption Index (SCI) | 41.2 | 0–100 (100 = cleanest) | Households — perception & experience |
| Transparency International CPI | 21 | 0–100 (100 = cleanest) | Experts & business surveys |
| World Bank Control of Corruption | -1.4 | ≈ −2.5 to 2.5 | Aggregated expert sources |
Most recent year — SCI 2022, CPI 2022, CCI 2022. The SCD also publishes region-anchored SUB-CPI and SUB-CCI series so the CPI and World Bank measures can be read at the regional level.
