Violent crime during each national leader's tenure, worldwide

The leaders of 3 countries since 1991, ranked against one another by how the violent crime changed from their 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.

#	Office-holder	Place	In office	Total	Per year	Chart

Sorted by total, highest first. Rows measure violent offences or their victims per 100,000 residents; what counts as violent differs between countries; 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 per 100k; "per year" divides them by the years in office. Tenures with under 12 months, or under three observations, are left out. Data as of Oct 2026.
