on track to reach 7 billion in 2011,

number of people by area.

This map is a choropleth (shading) map and illustrates population density.
The darker the colour the greater the population density.
The map shows that world population distribution is uneven. Some areas
have a high population density while others have a low population
density.
Areas of high population density tend to be located between 20° and
60°N. This area contains a large land area and a relatively temperate
climate.

17. "Population density" is the term that describes the number of individuals
occupying an area in relation to the size of that area.
The population density is derived by dividing the number of people by the area they occupy.
