Population & Health Rankings
How many people, how long they live, and how fast populations are changing. These rankings cover the human story behind the numbers. Compare life expectancy, population density, median age, and more.
Countries by median age
Did you know the median age in some African nations is under 20, while in parts of Europe it tops 45? That 25-year gap will define economic competition and geopolitical power for decades to come.
Countries by population density
Did you know Bangladesh is more densely packed than almost any country on Earth, despite having no megacity that dominates its population? Density shapes housing, infrastructure, and quality of life in ways most people don't consider.
Countries by population growth rate
South Sudan’s population is growing at 5.86% per year—while Saint Martin is shrinking at -5.40%. That’s a staggering 11.26 percentage-point swing, meaning one country could double its population in just over a decade while another rapidly empties out. Few metrics capture global divergence as sharply as population growth.
Countries by population
Did you know India recently overtook China as the world's most populous nation, ending a six-decade streak? The demographic balance of power is changing — and the ripple effects will be enormous.
