Control of Corruption CC.EST
Tanzania's control of corruption was -0.28 in 2025, ranked 111th globally. This represents a 13.0% increase from 2024. Data from World Bank WGI, covering 1996–2025.
Overview
Tanzania's control of corruption stood at -0.28 in 2025, a rise of +0.04 from 2023. Based on recent trends, this figure is projected to reach -0.28 by 2025. Tanzania ranked 111th globally.
Tanzania’s score on the World Bank’s Control of Corruption index improved markedly from its 1996 baseline of –0.70 to a peak of –0.23 in 2006, before slipping to an all‑time trough of –0.84 in 2002 and then recovering to –0.28 in 2025, placing the country 111th globally out of the surveyed economies. The 2025 figure matches Belize’s –0.28 and lies close to Vietnam’s –0.25, suggesting Tanzania now performs comparably with other lower‑middle‑income states that have modest but persistent governance challenges. Over the 26‑year coverage period, the trajectory reflects a gradual reduction in perceived corruption since the early 2000s, yet the index remains well below the midpoint of the scale, indicating that substantial institutional reforms are still required. Continued strengthening of anti‑corruption agencies, greater transparency in public procurement, and enhanced civil‑society oversight could accelerate progress and shift Tanzania’s standing upward in future assessments.
