Geography: Population: 2 of 3

• Sparsely Populated– Places which contain few people per km sq.
• Densely populated– Places which contain many people per km sq.
• Population density – The number of people per km sq.

Stages of the DTM
Stage 1: Limited medical care + poor diet = high infant mortality.

• Strong religious values = high birth rate. Example: Indigenous Tribes in the Amazon
Rainforest.
Stage 2: Increase in access to basic medical care = decreased infant mortality and death rate.

• Diets also improved. Birth rate remains high as children are needed to work on farms.
• Birth rate also remains high as religion plays a significant role in society. Example:
Afghanistan.
Factors affecting Population Density Stage 3: Decrease in birth rate as women are able to access education.
Human = Red
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.
Stage 4: Birth rate remains low and fluctuating as women put careers before having children.
Fertile soil Poor soils
• Death rate remains low due to improvements in healthcare, diet and physical fitness.
Access to infrastructure and Lack of access to infrastructure
services • Total population reaches its peak and begins to fall. Example: The UK.
Access to high paying jobs Low paying, low skill jobs Stage 5: Death rate is greater than birth rate = natural decrease.

• Ageing population due to improvements in healthcare, diet and physical fitness.

• Children are expensive so birth rates continue to fall.
