Imagine a world map highlighting countries where the majority of the population has been born since the year 2000. This visualization sheds light on nations with predominantly young populations, offering insights into global demographic trends.

In several African countries, the median age is remarkably low, indicating that more than half of their populations are under 20 years old. For instance, Niger stands out with a median age of just 15.2 years, making it one of the youngest nations globally. Similarly, Uganda and Chad have median ages of 15.7 and 16.6 years, respectively.
These youthful demographics are primarily due to high birth rates and improving healthcare systems, which have led to lower infant mortality rates. However, as education and economic opportunities expand, fertility rates in some of these countries are beginning to decline. For example, Kenya’s fertility rate has decreased from nearly eight children per woman in the 1970s to just over three today.
Conversely, many developed nations are experiencing aging populations. Japan, for example, has seen its median age rise from 22 years in 1950 to 48 years in 2020, influenced by a low fertility rate of 1.4 births per woman.
Similarly, European countries like Italy and Germany are facing demographic shifts due to low birth rates and higher life expectancy. Without immigration, Europe’s population is projected to decline significantly, with countries like Italy potentially experiencing drastic population decreases.
Understanding these demographic trends is crucial for global planning and development. Countries with younger populations may experience rapid labor force growth, while nations with aging populations could face challenges related to workforce shortages and increased healthcare demands.
