Population structure
I can interpret and analyse population pyramids.
Lesson details
Key learning points
- A population pyramid shows the age and gender balance for a country.
- A wider base on a pyramid means that there is a high birth rate.
- The taller a pyramid is, the greater the life expectancy.
- Bulges in population pyramids show years where there was a baby boom.
Keywords
Population pyramid - a graphical representation of age and gender distribution in a population
Birth rate - the number of live births per 1000 people per year
Life expectancy - the average number of years a person is expected to live
Common misconception
All population pyramids are pyramid-shaped.
Population pyramids can have different shapes depending on demographic factors. Some may be more rectangular or even inverted, reflecting various population structures.
Give students some figures and graph paper to draw their own population pyramids.
