Source: Alexander and Welzel (2011); Alexander, Inglehart and Welzel (2012). Categorization is available in annual measures for most countries of the world from 1996 to 2006.
Scaling: The factor scores are standardized into a range from minimum 0 (for the lowest ever observed corruption control) to maximum 1.0 (for the highest ever observed corruption control), with fractions for intermediate positions. Note: In the original data there exists two different observations for Dominica, the value has been recoded to missing for this country.
