The powerline is the headline share of world power, running from the state’s first ranked year (benchmark estimates with wide error bars before 1816). Latent power is material mass a state could mobilise (population, manpower, heavy industry). Recognised power is what the system actually treats it as (military spending, productive economy, reach, and status such as a Security Council seat or nuclear arsenal). When latent runs above recognised, a power is rising or under-rated; when recognised runs higher, it is punching above its weight or coasting on prestige. Material sub-indices run 1816 through 2016.
