A population pyramid is a graph. It has two back-to-back bars. These bars show the population in groups of ages, with woman in one side and man in the other side.

The pyramids usually show the development of a country. When you look a pyramid you can see the life conditions of the country.

There are three types of population pyramids:

  • Stationary pyramid
  • Expansive pyramid
  • Constrictive pyramid

In this type of graph, a wide base means a very high birth rate and a narrow base means a high death rate.
