Areas of high population concentration are said to ecumenical. These are areas of attraction, whether due to a physical (heat, rich soil) or economic (industrialized urban area with developed tertiary sector).
The areas considered anecumenae they are those little occupied, difficult to survive, where the physical factor predominates (too cold, desert regions, forests, mountains, among others). They are also known as demographic gaps.
New York - Example of Ecumenical Area
Sahara Desert - Example of Anecumenous Area
Planet earth is not well distributed in terms of population. The countries' coastlines are regions of high population concentration, with some exception. The most populous region in the world is Southeast Asia, with over one third of the total population on the planet.
Chinese beach - evidence of overpopulation
However, it is in Western Europe that the great demographic densities lie.

78% of the world's population lives in underdeveloped countries; 22% of the world's population lives in rich countries.

In Brazil
The Brazilian population is unevenly distributed throughout the territory. Brazil is a populous, sparsely populated country whose population is concentrated in a range that runs from the coast (east) to 700 km in a westerly (inland) direction. This is due to historical issues of European colonization.

Population growth
A country's population can grow in two ways: through vegetative growth and through migratory flow.
- Vegetative or natural growth is the difference between birth rate and mortality rate.
Example vegetative growth in Brazil
- Migration flow is a generic reference to the movement of entry (immigration) and exit of people (emigration).

I confirm. I agree with all of the above-said.
Remarkable, very useful thought
Another variant is possible
Exactly! I think that is the excellent idea.
I'm sorry, but in my opinion, you are wrong. Write to me in PM, it talks to you.
In it something is. Thanks for an explanation, I too consider, that the easier the better...
