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 in the upper right. That will let you know which index measures that quality.
