Real trajectories bend as fertility, mortality and migration shift, which is why the chart below shows both history and projection.
Among its first-level divisions, the largest by our modelled allocation is Žilina, holding an estimated 32.4% of the national population. The full breakdown of all 8 states and regions is in the table below — regional figures outside Sudan are modelled estimates built on real region names, and are flagged as such.
Literacy stands near 99.0% and adult smoking prevalence around 26.0%, with life expectancy at about 73.7 years. Baselines come from UN World Population Prospects, the World Bank, WHO surveys, WorldPop and HDX; the counters project them forward in real time — the method, and every caveat, is documented on our data sources page.
