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.

  1. Imagine being 14 and half of your country being younger than you.

  2. Really cool to look at

    Who was “highest” and “lowest” in 1950? and where did they end up?

  3. I’d like to see this with the country lines color coded by continent.

  5. Is the Central African Republic getting lower because a lot of people are dying before becoming older or is it that they just have a crazy high birth rate?

  6. Another thing that’d be neat to add if you have the data for it, is a line for the median age of the *world*.

  7. It’s kinda sad we’re watching multiple populations crash and cultures dying in real-time but such is life.

  8. In 1950, the world population was 2.5 billion. Now it is over 8 billion. The demographic crisis is unfortunate because our leading economic systems require impossible, endless growth and ignore factors like the Holocene Extinction and Climate Change. Our environment’s carrying capacity doesn’t care about our flawed economic systems, though.

  9. I’m older than over half of Africa. I’m 21.
