For each nuclear state, the graph shows average yield per warhead. Scale is logarithmic. Five nations have released varying amounts of information regarding their arsenals; these figures are indicated by solid lines. Five declared or suspected nuclear states have not released such information; indicated by dashed lines, these figures are uncertain. Figures for the PRC and Israel in particular are uncertain by perhaps 70%.
