Saint Helena, Ascension and Tristan da Cunha · share of world power, 1991–2026

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.
