About This Dataset
Nuclear Weapon Tests Conducted by CountryTesting was overwhelmingly a two-superpower affair: the United States (1,030 tests) and the Soviet Union / Russia (715) together account for roughly 83% of all nuclear tests ever conducted.

The sharp fall-off after the top three reflects both the maturity of the US and Soviet arsenals and the 1996 Comprehensive Nuclear-Test-Ban Treaty, after which only North Korea has continued testing. The data captures how a technology pioneered by two rivals slowly spread to a small club of states.
