Levels are per cent changes, rates are differences in points; "per year" compounds levels and divides rates. Tenures with under 12 months, or under three observations, are left out. points, 0 to 100, higher is better · World Bank, Worldwide Governance Indicators (GOV_WGI_RQ.SC): perceptions of the government's ability to make and carry out sound rules that let private business form and compete, a score from 0 to 100 with its 90 % interval; the European Union line is Politare's unweighted mean of the 27 members' scores · country data · as of Sep 2026.
