📈 Power over timeThe Power Atlas →
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.

👥 Population over time
Our World in Data population (CC BY): UN WPP 2024 from 1950, Gapminder v7 1800-1949, HYDE 3.3 earlier; today's borders. Figures above are as of 2023, the last year that is estimated rather than forecast. The dashed tail to 2026 is a UN WPP medium-variant projection. It is drawn because the line should reach the present, and drawn differently because it has not happened yet: no rank, peak or share on this page uses it. Before 1950 the series is reconstruction rather than contemporaneous statistics, which is worth knowing when a country’s peak sits back there. The current population shown elsewhere on this page comes from the workbook and is unchanged by this. Note that people and share of world can move in opposite directions. A country can grow steadily and still become a smaller part of humanity, which is what happened to almost every rich country after 1960.
👥 To 2100
The UN’s probabilistic projection for Sierra Leone: the median with its 80% and 95% bands, the UN’s own high, low and zero-migration scenarios beside it. Not this site’s model; the site reads it and says what it implies.
Tap or drag across the chart to read any year: the estimate to 2023, then the UN median, its bands and the scenarios.
What drives it
Births, deaths and net migration on the UN medium path, with fertility, life expectancy and median age, every decade from 1950.
