What is shown in a population pyramid?
The population pyramid represents the breakdown of the population by gender and age at a given point in time. It consists of two histograms, one for each gender (by convention, men on the left and women on the right) where the numbers are shown horizontally and the ages vertically.
What factors affect the population pyramid?
Economic variations (such as a depression or job growth), political changes (such as a new policy on family planning or a new tax break on dependents), conflicts (such as wars), public health trends and natural events (such as long-term droughts or an earthquake) can impact birth and/or death rates.
What are the stages of population pyramid?
The five stages of population pyramids are high fluctuating, early expanding, late expanding, low fluctuating, and natural decrease.
What does a Stage 2 population pyramid look like?

What are the two most important composition of a population?
