Physical = Black • Decrease in birth rate as religion loses importance in society and contraception
becomes available.

Densely Populated Sparsely Populated • Death rate continues to decline due to improvements in diet, healthcare and physical
fitness.
Pleasant climate Steep slopes • Total population continues to increase as there is natural increase. Example: India. Application: The UK’s Ageing Population
Stage 4: Birth rate remains low and fluctuating as women put careers before having children.
