GEOGRAPHY & CARTOGRAPHY CALCULATOR
Indexcorruption Rank
A precise tool.
What is the Indexcorruption Rank & How does it work?
The Corruption Perception Index (CPI) is a composite indicator that aggregates expert assessments and opinion surveys to gauge perceived levels of public sector corruption in countries worldwide.
Geographers and cartographers often map CPI scores to visualize spatial patterns of governance, revealing regional clusters of high or low perceived corruption.
To translate a raw CPI score into a comparative rank, the following linear scaling formula is applied, normalizing the score within the dataset’s range and assigning a rank among N countries.
R = \frac{S_{\max} – S}{S_{\max} – S_{\min}} \times (N – 1) + 1
R = rank, S = country CPI score, S_{\max} = highest CPI score in dataset, S_{\min} = lowest CPI score, N = total number of countries

Who uses the Corruption Perception Index?
Geographers, cartographers, and policymakers use the CPI to visualize spatial patterns of governance and identify regional clusters of corruption.
What does a high CPI score indicate?
A high CPI score indicates lower perceived levels of public sector corruption in a country.
How often is the Corruption Perception Index updated?
The CPI is typically updated annually by Transparency International.
Can I use this calculator for any country?
Yes, you can use this calculator for any country as long as you have its corresponding CPI score.
What does the rank represent in terms of corruption levels?
The rank represents how a country’s perceived corruption level compares to others globally, with lower ranks indicating less corruption.
