Real trajectories bend as fertility, mortality and migration shift, which is why the chart below shows both history and projection.
Literacy stands near 85.0% and adult smoking prevalence around 17.0%, with life expectancy at about 73.6 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.
