Demographic profile

Guinea is the 76th most populous of the 238 countries and territories tracked on this site, home to about 0.19% of everyone alive. Within Western Africa, it ranks 8 of 16.

Each day brings roughly 1,521 births and 380 deaths, adding about 416,741 people over a year. At the current natural-increase rate of 2.7% annually, the population would double in roughly 26 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 Yomou, holding an estimated 19.1% of the national population. The full breakdown of all 34 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 55.0% and adult smoking prevalence around 8.0%, with life expectancy at about 45.6 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.
