The document discusses population density and factors that influence it. It provides data on the population and population densities of various countries. Belgium has a high population density of 360 people/km2 while Russia has a much lower density of 8 people/km2 due to its larger size. Countries with the highest population densities include Monaco, Singapore, and Malta, while China and India have the largest total populations. Areas tend to have higher densities due to positive physical and human factors like good climate, resources, and economy, while low densities are seen in areas with extreme weather, few resources, and economic/political challenges.

1. POPULATION
HOW IS POPULATION STUDIED?
We can count the total
number of inhabitants of a
place or a country
ABSOLUTE POPULATION
We can measure the ratio
between the number of
inhabitants and the size of
the area they occupy
POPULATION DENSITY
Number of inhabitants divided by
the surface area of the place

high technology High level of life
Goverments invest in
services, towns, banks…

5. NEGATIVE FACTORS GIVING AREAS WITH LOW
POPULATION DENSITIES
