How Greece compares: SCD vs. the CPI and World Bank

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 Greece into 13 regions.

Index	Latest	Scale	Based on
Subnational Corruption Index (SCI)	63.9	0–100 (100 = cleanest)	Households — perception & experience
Transparency International CPI	52	0–100 (100 = cleanest)	Experts & business surveys
World Bank Control of Corruption	0	≈ −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.
