The spread
176 countries, one dot each, on one scale — further right is a higher value. Half the countries are above 0.518; a quarter are above 0.759, and a quarter below 0.206. The bar in each row marks that continent’s middle country.
04All 176 ever measured
Every country
In order, highest value first — position 1 is the highest value, the way V-Dem Institute, University of Gothenburg’s own tables read. “=” marks a position shared with another country. V-Dem Institute, University of Gothenburg ranks nobody on this measure; the position is derived here by ordering the published values. ⚠ Higher is worse, the reverse of every other V-Dem measure on this site, so the derived position puts the most corrupt country first. It is expert-coded by V-Dem, a different method from the Corruption Perceptions Index on this site, so the two can disagree about a country.

About political corruption
V-Dem's Political Corruption Index asks how pervasive corruption is across the state — bribery and embezzlement in the executive and the wider public sector, and corruption in the legislature and the courts. It runs from 0 to 1, and unlike V-Dem's other indices a higher figure is worse: more corrupt.
What the number is: Political corruption index (0–1; higher = more corrupt).
What it does not measure
It is an expert assessment of corruption in the state; it does not count prosecutions or measure corruption in private business.

From V-Dem Institute, University of Gothenburg, under CC BY-SA 4.0. From the V-Dem Institute's Country-Year Core dataset (v16), University of Gothenburg, published under CC BY-SA 4.0. V-Dem's data runs back to 1789; the series here starts in 1990 so that every row belongs to a present-day country.

How this page reads the numbers
- V-Dem Institute, University of Gothenburg ranks nobody on this measure. The position is derived by Nations Inquiry by ordering the published values; equal values share a position.
- 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 file itself, column by column — where it came from, what each column holds, and every edition as a CSV — is on its dataset page.
