Description
The Worldwide Governance Indicators (WGI) reports aggregate and individual governance indicators for over 200 countries for six dimensions of governance: Voice and Accountability, Political Stability and Absence of Violence, Government Effectiveness, Regulatory Quality, Rule of Law, Control of Corruption

Index Calculation Mechanism
These aggregate indicators combine the views of a large number of enterprise, citizen and expert survey respondents in industrial and developing countries. They are based on over 30 individual data sources produced by a variety of survey institutes, think tanks, non-governmental organizations, international organizations, and private sector firms.

The indicators are calculated by giving a value ranges from (-2.5 very low performance) to (2.5 as a very high performance), and a percentage ordered be between (0) least to (100) the highest.

For example, the government effectiveness indicator of Bahrain in 2016 was 65, meaning that Bahrain government effectiveness is better than 65% of the countries included in the report.
