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 The Vatican, while those with the largest total populations are China, India, and the United States. High population densities are influenced by positive physical and human factors like good climate, resources, and economy, while low densities result from challenges such as harsh weather, lack of resources, and economic or political problems.

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
