Governance scores
The World Bank's Worldwide Governance Indicators combine surveys of households and firms with assessments by public, private and non-governmental bodies. Each score runs from 0 to 100; higher means the sources rate governance better. They measure perceptions, and each has a margin of error.
- Voice and accountability
- Measures how far citizens can choose their government, and freedom of expression, association and the media.
- Political stability and absence of violence
- Measures the likelihood of political instability or politically motivated violence, including terrorism.
- Government effectiveness
- Measures the quality of public services and the civil service, and how independent they are from political pressure.
- Regulatory quality
- Measures the government's ability to make and carry out policies that let the private sector develop.
- Rule of law
- Measures confidence in and respect for the rules of society, including contract enforcement, property rights, the police and the courts.
- Control of corruption
- Measures how far public power is used for private gain, including petty and grand corruption and "capture" of the state by elites.
