Watch the population race, 1950 to 2100
For most of modern history the ranking of the world’s biggest countries felt fixed: China on top, India close behind, a familiar cast trailing them. This animation lets you watch that order actually change, year by year, as each country’s population grows, peaks and, for many, begins to fall.
Press play and the bars race. India overtakes China around 2023. Europe and East Asia slip down the board as they stop growing, while one country after another from sub-Saharan Africa, led by Nigeria, climbs into the top ranks. By 2100 the chart looks nothing like 1950. All figures use the UN’s medium-variant projection.
What you are seeing
Each bar is a country, sized by its population on January 1 of the displayed year and ranked from largest at the top. Only the top 12 are shown at any moment, so countries enter from below as they grow and drop off the bottom as others overtake them. Values are interpolated smoothly between years, and bars slide up or down whenever the ranking changes. The figures come from UN World Population Prospects 2024, covering 1950 to 2100. Projections are scenarios, not predictions.
