Did you know that the population of Nigeria in the year 2000 was 122 million? That's a lot of people. But fast forward to 2022, and the population has skyrocketed to 218.5 million. That's a massive increase. On the other hand, Japan had a population of 126 million in 2000, but it has actually decreased to 123.9 million in 2022. It's fascinating how populations can change over time. Nigeria is booming, while Japan is experiencing a decline. It just goes to show how different countries can have unique population dynamics.
