- 13. LEDW This country has a high BR – the pyramid has a wide base But it also has a high DR – shown by the steeply sloping pyramid
- 14. Falling BR In some LEDCs, the Government is encouraging families to have fewer children so the BR is falling – the base is becoming narrower.
- 15. MEDW Low DR – pyramid is wider at the top The largest group of people was born around 40 years ago – ‘baby boomers’. There are roughly the same amount of people in each age category – BR is stable. Male Female Population in millions
- 16. Declining population BR is falling – the number of people in each category is getting smaller In the future the elderly population will make up the largest section of the population – an ageing population
- 17. MEDW vs LEDW Male Female Population in millions
