1. Chapter 2: Population: Key Issue 2
Where Has the World’s Population Increased?
1. Define each of the following:
a. Crude birth rate (CBR):
b. Crude death rate (CDR):
c. Natural increase rate (NIR):
2. What is the NIR today?
3. When did the global NIR peak, and what was it?
4. About how many people are being added to the world’s population each year?
5. Define doubling time:
6. In what world regions is most growth occurring?
7. What is the global “average” TFR?

2. 8. Note the rates and locations of the global “highs and lows” in TFR.
9. Define the following:
a. infant mortality rate:
b. life expectancy:
10. How are these mortality rates distributed globally in terms of the developed and developing worlds?
11. Please use the map on page 56 of your textbook to color the map “Life Expectancy At Birth” below. Create a
58
map key, and then choose one country from each of the bands of life expectancy to speculate (have an
educated guess) as to why that country has the life expectancy that it does.
LIFE EXPECTANCY AT BIRTH
80 and above – country
reason for life expectancy

3. 75-79 – country
reason for life expectancy
70-74 – country
reason for life expectancy
60-69 – country
reason for life expectancy
below 60 – country
reason for life expectancy
