The Freedom from Corruption index for Tonga from the Heritage Foundation uses mostly the data from Transparency International, an NGO that tracks corruption perceptions around the world.

Definition: The score for the Freedom of corruption index is derived primarily from Transparency International’s Corruption Perceptions Index. For countries that are not covered in the CPI the freedom from corruption score is determined by using information from internationally recognized and reliable sources. Higher index values denote lower level of corruption.
