Based on expert opinion, the Corruption Perceptions Index measures the perceived levels of public sector corruption worldwide.

Dark red indicates a highly corrupt public sector. Lighter red and orange countries fare a bit better, but corruption among public institutions and employees is still common. Yellow countries are perceived as cleaner, but not perfect.

The scale of the issue is huge. Sixty-eight per cent of countries worldwide have a serious corruption problem. Half of the G20 are among them.

Move around the map and check out how your country ransk. You can move left or right and zoom in and out. Feeling down, just remember we all have more work to do as not one single country, anywhere in the world, is corruption-free.
