Corruption in South Africa includes the improper use of public resources for private ends, including bribery and improper favouritism. The 2017 Transparency International Corruption Perceptions Index assigned South Africa a score of 43 out of 100, ranking South Africa 71 out of 180 countries; a high score and a low ranking signals that the country's public sector is perceived to be honest. There was a marginal improvement by 2021, when South Africa received a score of 44, ranking it 70 out of 180 countries. Nonetheless, this remains below its score of 45 in 2016. Countries with scores below 50 are believed to have serious corruption problems.
