Population Density and Distribution

A Dot Distribution map is able to show the population density of very

small areas. They don't show the country as a whole, but show the

little regions where people are concentrated. So it is very hard to

compare countries to each other. In the other hand, the Population

Density maps are maps with countries that are shaded according to

their population density as a whole. So, we can compare countries, but

can't see the small regions in the country, that have a denser

population than the other regions.

Bangladesh, India, Japan, France, Holland and Belgium are densely

populated.

Canada, Australia, Russia, Mongolia, Saudi Arabia and Bolivia are

sparsely populated.

People want to live in the best conditions possible, even though they

can't always manage to live in these conditions. These conditions are:

Climate, which allows people to make agriculture. The best climate for

agriculture is temperate climate, with no extremes of temperature or

precipitation. If there are extremes, no crops can be grown and people

won't be able to continue their lives. So areas with temperate

climates have a denser population than extreme climates. A second

effect of climate on people is that people are not able to live in

extreme climates, especially cold temperatures.

Topography, which divides into three parts; altitude, slope and

aspect. Altitude is the height above sea level. This effects both the

temperature and the amount of oxygen in the air. Temperature drops by

6ºC at every 1000 meters up; as well as the amount of oxygen. So

usually, the higher the altitude, the more sparse the population, with

few exceptions. Slope is the incline of the land. It effects

agriculture and transportation. If the land is horizontal, all kinds

of agriculture may be done and transportation is easy. But as the

slope gets steeper, limited agriculture may be done and transportation

is harder. If it is very steep, neither agriculture nor transportation

is available. So, the steeper the slope, the more sparse the

population.
