[OC] Median Age Extremes: Japan and the Central African Republic Have the Oldest and Youngest Populations — But They Shared the Same Median Age in 1950

Data source: Median Age – Our World in Data

Tools used: Matplotlib

Explanations:

• Japan has one of the world’s oldest populations due to decades of low birth rates and long life expectancy, but they also lost a large part of their adult population during World War II
• The Central African Republic have a young population, driven by high birth rates and lower life expectancy. Armed conflict and instability reduced the median age significantly since 2010.

I removed countries with a population below 100,000 since they often have strange demographics that don’t follow a natural trend, such as Vatican City and Monaco who both have abnormally high median ages.
