I. Key Issue 1: Where is the World’s Population Distributed?
A. What is a census? What function does it serve?
A census aims to count the entire population of a country, and at the location
where each person usually lives.

Other clusters are the North American cluster.
3. Name and define the 4 Sparsely Populated Regions
The four sparsely populated regions are:
1- Dry Lands: Since the area is dry for farming not many people want to
live there.
2- Cold Lands: Areas that are covered with ice or have permanently
frozen ground.
3- Wet Lands: Lands that receive high levels of precipitation.
4- High Lands: Lands where the elevation is high.
4. Define ecumene
The permanently inhabited portion of the earth as distinguished from the
uninhabited or temporarily inhabited area.

Over time, ecumene has increased slightly. This has been caused by a
number of factors, but the most significant is overpopulation.
