This document summarizes Transparency International's 2019 Corruption Perceptions Index (CPI). The CPI scores 180 countries on perceived levels of public sector corruption, with 100 being very clean and 0 being highly corrupt. The average global score is 43 out of 100. Two-thirds of countries score below 50. The top scoring countries are New Zealand, Denmark, Finland, Singapore, and Sweden. The lowest scoring countries are Somalia, South Sudan, and Syria. The report finds that reducing the influence of money in politics and promoting inclusive decision-making are essential to curb corruption. Countries with stronger campaign finance regulations and more open consultation processes tend to have lower corruption.
