3. Global population density and the world’s largest cities

4. The world’s population is distributed unevenly across the globe.
Although there is an average of 47 persons per square kilometre, the population density varies considerably.
Some places have below 10 persons per square kilometre e.g. inland central Asia and Australia.
Regions of highest density are clustered in Europe, East and South-East Asia and in the eastern half of the United States of America e.g. Germany has 232 persons per square kilometre and Japan has 349 persons per square kilometre.
Dhaka, the capital city of Bangladesh (see image), is considered to be the most densely populated place in the world, with an estimated  persons per square kilometre.
population density - the number of people within a given area, usually per square kilometre.

5. Why does population distribution vary so much?
Physical factors play a large part e.g. availability of:
Fresh water
Fertile soil
Moderate climate
Human factors also influence e.g. Urban places attract people for employment e.g. manufacturing in Mumbai.
Government policies may also affect population distribution e.g. service centres based around resource development, as in the Pilbara in Western Australia.

6. Life Expectancy – a well being indicator
Life expectancy around the world started to increase in the mid 1700s due to improvements in farming techniques, working conditions, nutrition, medicine and hygiene.
There is a clear interconnection between wealth and life expectancy: wealthier people in all countries can expect to live longer than poorer people.
In general, women outlive men.
A higher income enables people to have better access to education, food, clean water and health care.
Life expectancy is decreasing rather than increasing is sub- Saharan Africa, where many countries have been affected by HIV and AIDS.

8. Child Mortality
Life expectancy is closely interconnected to child mortality i.e. countries with high death rates for children under five years of age have low life expectancy.
This is well above the United Nations Sustainable Development Goal 3 target of 25 deaths per 1000.
Young children are particularly vulnerable to infectious diseases due to their lower levels of immunity.
Major causes of death include pneumonia, diarrhoea, measles and malnutrition.
In wealthier households, child deaths are lower as these children are more likely to have better nutrition and to be immunised, and parents are more likely to be educated and aware of how to prevent disease.
