What is a population pyramid? (Structure population)
A graph that shows the number of males and females in each age group in a country at a particular time
What would a population pyramid look like for a country in stage 2 DTM? (Structure population)
- Wide base, high BR
- Not tall, low life expectancy
- Small in size, small total population
- Curved sides, not many make it to the name age category
What would a population pyramid look like for a country in stage 4 DTM? (Structure population)
- Narrowing base, fall in BR
- Tall, long life expectancy
- Large in size, big total population
- Large bulging sides, almost every lives to the next age category
Where will males and females be located on the graph? (Structure population)
Males = left hand side Females = right hand side
