Control of corruption during each office-holder's tenure, worldwide

42 offices, from presidents to mayors, in 40 countries, ranked against one another by how the control of corruption changed from each office-holder's first day in office, each on its own country's figures. Politare shows what happened during a tenure; it does not claim the office-holder caused it.

Showing 10 of 155 tenures.

Sorted by total, highest first. Rows measure the World Bank's Worldwide Governance Indicators score from 0 to 100, one method for every country; yearly; each place is read from its own statistics office's series (the row's chart names it), so a change is set against the place's own first day, never against another country's level. Every row is indexed to the last month, quarter or count complete before the first day in office ("from" marks a start that had to move because that period had no data, or because the period cut it). Changes are differences in points; "per year" divides them by the years in office. Tenures with under 12 months, or under three observations, are left out. Data as of Sep 2026.
