population pyramid
Demographic age diagram
A population pyramid is a bar graph showing the age and sex distribution of a population, with age groups stacked vertically and males on one side, females on the other.
The shape reveals demographic patterns: a wide base indicates high birth rates, a narrow top shows few elderly.
The population pyramid for Japan shows an aging society with a shrinking base.
