The spread
182 countries, one dot each, on one scale — further right is a higher value. Half the countries are above 39; a quarter are above 56, and a quarter below 28. The bar in each row marks that continent’s middle country.
04All 182 ever measured
Every country
In order, highest value first. “=” marks a rank shared with another country. These are perceptions, not counts. A country is only scored in a year at least three source surveys covered it, which is why the field moves between 168 and 182 countries.

Each point is one annual edition, named for the year it measures and published the following February. The 0–100 scale has been comparable year to year since 2012, so this line can be read as a real trend.

About Corruption Perceptions Index
Transparency International’s Corruption Perceptions Index scores how corrupt a country’s public sector is believed to be, from 0 (highly corrupt) to 100 (very clean). It is built from 13 expert and business surveys rather than counted cases — the best available read on something nobody can measure directly.
What the number is: CPI score (0–100, where 100 is very clean).
What it does not measure
It measures how corrupt experts and business people believe a public sector is, not proven cases, and it does not cover private-sector corruption or money laundered through other countries.

12Questions
Corruption Perceptions Index: questions and answers
Which country has the highest Corruption Perceptions Index?
Denmark, at 89, among the 182 countries compared in 2025.

2 countries share the lowest reading, 9, among the 182 compared in 2025, so no single country is named.
How many countries does the Corruption Perceptions Index cover?
182 in 2025. The number measured varies from 168 to 182 between editions.
What is the world average Corruption Perceptions Index?
This site does not calculate a world average, which would depend on how countries are weighted. In the middle country of the 182 compared in 2025, the figure was 39.
Is this Transparency International’s own ranking?
Yes. The rank shown is the one Transparency International publishes.
How often is the Corruption Perceptions Index published?
This site holds 14 editions, describing 2012 to 2025.
Where does the data come from, and can I download it?
From Transparency International, under CC BY 4.0 (the data), CC BY-ND 4.0 (the website and report). Imported from Transparency International’s own results spreadsheet. The series starts at 2012 on TI’s instruction: earlier scores used a different scale and were only ever comparable within a single year. Every edition is available on this site’s Datasets pages as a full table, unrounded.

How this page reads the numbers
- The rank is Transparency International’s own, as published.
- Which end is better follows the publisher’s own reading of the measure.
- A country is named at an end only when it holds that value alone. Where several share it, the page says how many and names none first.
- Values are stored exactly as published and trimmed only for display. “The middle country” is the median of the countries measured, not a world average.
The full note on this data
14 editions, 2012 to 2025, imported from Transparency International's own results spreadsheet — one file carrying every edition. Each edition is named for the year it measures and is published the following February. ⚠ The series starts at 2012 on the publisher's own instruction: TI has run a CPI since 1995, but rebuilt it in 2012 onto a 0–100 scale that is comparable year to year, and states that earlier scores were only ever comparable within a single year. TI publishes a rank column for 2017 onward only; the ranks for 2012–2016 are derived by ordering the score, a derivation verified to reproduce all 1,622 of TI's own published ranks exactly. The score is a perceptions measure built from 13 expert and business surveys, not a count of corruption — a country is only scored in a year at least three of those sources cover it, which is why the field ranges from 168 to 182 countries.
