Corruption is still a big problem globally. But a new study says the issue might be improving overall.
Transparency International released its annual Corruptions Perceptions Index Wednesday, and it says more countries achieved better scores in 2015 than the previous year. Countries that got lower scores indicate more corruption.
For least corrupt, Denmark took the top spot, followed by Finland and Sweden.
The U.S. dropped one spot to 16th, tying with Austria.
The most dramatic fall in the rankings was Brazil, dropping seven spots. This is due in part to a bribery scandal within a governmental oil company.
Transparency International's annual report looks at factors like law enforcement and conflict, and experts offer their opinions on corruption levels in a country. This is why countries actively fighting corruption can still fare decently in the rankings.
