Demographic profile

Each day brings roughly 31 births and 15 deaths, adding about 5,843 people over a year. At the current natural-increase rate of 0.7% annually, the population would double in roughly 100 years if the rate held. 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 Mahaica-Berbice, holding an estimated 29.5% of the national population. The full breakdown of all 10 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 94.0% and adult smoking prevalence around 12.0%, with life expectancy at about 64.0 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.
