Which countries are growing the fastest?
Between 2019 and 2020, the world’s population grew by 1.1 percent. That may sound like a small number but it is more than 80 million people. While the world’s population is expected to increase over the next few decades, the speed at which it grows is slowing down.
The population of India is expected to overtake China by 2024, based on projections made by the UN’s Population Division. India would then become the world’s most populous country comprising one out of every six people on the Earth.
The animation below shows the top 10 fastest-growing countries per decade since the 1950s.
The fastest-growing continent over the past five years was Africa (2.51 percent) and the slowest growing was Europe (0.12 percent). In countries in the Middle East, an influx of foreign workers combined with a higher standard of living led to the sharpest population increases over the decades.
If you are curious, the countries with the maximum decreases in population size over the past five years were: Lithuania (-1.48 percent), Latvia (-1.15 percent), Venezuela (-1.13 percent), Bosnia and Herzegovina (-0.89 percent) and Bulgaria (-0.71 percent).
