Estimated nuclear warhead stockpile; not applicable to non-nuclear states.· Every series comes from ONE dataset: the countries Citoyen covers and the world total are read together, from the same source and the same release. « Rest of the world » is the world total minus the 19 countries covered (the European Union is left out, it contains France, Germany and Italy and would be counted twice). The six largest countries on the indicator are drawn on their own, the other covered countries are grouped. A year is drawn only when every country and the world are published: a missing country would otherwise land in « rest of the world » as a fake jump.· Nuclear warheads in the military stockpiles of the nine nuclear powers, estimated by the Federation of American Scientists (read through Our World in Data). Retired warheads awaiting dismantlement are not counted. The world total is the sum of the nine; the rest of the world is Pakistan, Israel and North Korea. Russia includes the Soviet Union before 1992. Covered countries without nuclear weapons count 0 (South Africa dismantled its six warheads around 1990). The exact numbers are secret: these are estimates.· Licence : Estimates of the Federation of American Scientists, reused with the source cited· Published May 13, 2026
