Dear student
Please find your answer below to the asked query

Expanding age pyramid
Stable age pyramid

This type of graph has a triangular shape, with a very wide
base and pointed apex
This type of population distribution shows a rectangular or
squarish shape, with almost the same number of people in all
age

Each age group shows a bar less wider than that of the age
group before it, indicating that more people die at each higher
group
There is a slight taper at the top, which is perfectly natural,
due to more deaths occurring among the elderly

Example - many third world countries like India, China
Example - Austria follow this pattern
