Be careful when using these indexes. They measure qualities that are difficult to quantify. Moreover, methodologies often change year to year; therefore, multiyear comparisons are often invalid. For these reasons, it is important to know the methodologies used to derive these cross country comparisons before using them. Most of the indexes included provide their methodology.
Search tip: If you are looking for an indicator, e.g. stability, do a search in the search box for the database that you select. That will let you know which index measures that quality.

- Global Integrity Report (2004, 2006- ) from Global Integrity
Evaluates both anti-corruption legal frameworks and the practical implementation and enforcement of those frameworks. Each country assessment comprises two core elements: a qualitative Reporter's Notebook and a quantitative Integrity Indicators scorecard.
An Integrity Indicators scorecard assesses the existence, effectiveness, and citizen access to key governance and anti-corruption mechanisms through more than 300 actionable indicators. It examines issues such as transparency of the public procurement process, media freedom, asset disclosure requirements, and conflicts of interest regulations. Scorecards take into account both existing legal measures on the books and de facto realities of practical implementation in each country. They are scored by a lead in-country researcher and blindly reviewed by a panel of peer reviewers, a mix of other in-country experts as well as outside experts. Reporter's Notebooks are reported and written by in-country journalists and blindly reviewed by the same peer review panel.
