Indonesia's 2017 Corruption Perception Index (CPI) was categorized as low, ranking 98th out of 180 surveyed countries. This is reflected in Transparency.org's data, where Indonesia's CPI scored 37 on a scale of 0-100. An index closer to 0 indicates higher corruption, while a score closer to 100 indicates a cleaner environment. The high number of corruption cases in the political and law enforcement sectors keeps Indonesia's CPI low.
Compared to New Zealand, which received the highest score (89), Indonesia's CPI lagged by 52 points. Compared to Somalia, which had the lowest score (9), the difference was only 28 points. Nevertheless, Indonesia's CPI improved to 37 in 2017 from 32 in 2012. At the ASEAN level, Indonesia's corruption perception is lower than that of Singapore, Malaysia, and Brunei Darussalam, but better than Thailand and Vietnam.
