Demographic profile
Indonesia is the 4th most populous of the 238 countries and territories tracked on this site, home to about 3.46% of everyone alive. Within Southeast Asia, it ranks 1 of 11.
Each day brings roughly 12,166 births and 5,451 deaths, adding about 2,452,603 people over a year. At the current natural-increase rate of 0.85% annually, the population would double in roughly 82 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 Maluku Utara, holding an estimated 17.7% of the national population. The full breakdown of all 43 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 96.4% and adult smoking prevalence around 37.6%, with life expectancy at about 70.1 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.
