Pgs. 44 – 53
Population Concentrations
1. The world’s population is highly clustered, or concentrated in certain regions.
FOUR major population concentrations are identified in the text. Shade and label
the areas of these concentrations on the map in red. TWO smaller concentrations,
or emerging clusters, are also identified. Shade and label these areas on the map in
blue.

Sparsely Populated Regions
3. Define ecumene:
The portion of the Earth’s surface occupied by permanent human settlement
4. What would non-ecumene mean?
The portion of the Earth’s surface unoccupied by permanent settlement
5. List the four “lands” which are sparsely populated in Earth in the table below. For
each region, briefly explain the reason that makes it inhospitable for human
habitation.
Sparsely Populated Land
Reason for Inhospitality
Dry Lands
Unable to grow crops; no intensive agriculture
Wet Lands
50-90 inches of rain per year; rain & heat deplete soil
nutrients hindering agriculture
Cold Lands
High Lands
Ground permanently frozen (permafrost); unsuitable for
planting; few animals survive
Snow covered mountains; steep land; sparsely settled
6. Use the maps on page 49 to prepare a sketch map that shows non-ecumene and
very sparsely inhabited lands.
Population Density
7.
Define arithmetic
density:
The total number of people divided by total land area
8.
Define physiological
density:
The number of people supported by a unit area of arable land (suited for
agriculture)
9.
What occurs the
higher the rate of physiological density?
Greater pressure people place on the land to produce enough food to feed its
people
10.
Define agricultural
density:
The ratio of farmers to the amount of arable land

Key Issue 2 – Where Has the World’s Population Increased?
Pgs. 53 – 56
1. Define crude birth rate (CBR):
Total number of live births in 1 year for every 1,000 people
2. Define crude death rate (CDR):
Total number of deaths in 1 year for every 1,000 people alive
3. Define natural increase rate (NIR):
Percentage a population grows in 1 year (subtract CDR from CBR)
Natural Increase
4. What is the NIR today?
1.2%
5. When did the global NIR peak, and what was it?
1963 at 2.2%
6. About how many people are being added to the world’s population each year?
80 million
7. Define doubling time:
The number of years needed to double a population assuming a constant rate
of natural increase
8. In what world regions is most growth occurring?
LDCs – S. Asia, Sub-Saharan Africa, E. Asia, S.E. Asia, Latin America, Middle East
Fertility
9. Define total fertility rate (TFR):
The average number of children a woman will have throughout childbearing
years
10. What is the global “average” TFR?
2.6
11. Note the rates and locations of the global “highs and lows” in TFR.
6.0 in Sub-Saharan Africa & 1.9 in Europe
Mortality
12.
Define infant
mortality rate:
The annual number of deaths of infants under 1 year of age compared to total
live births
13.
Define life
expectancy:
The average number of years a newborn can expect to live at the current
mortality levels
14.
How are these
mortality rates distributed globally, in terms of the developed and developing
worlds?
The infant mortality rate in higher in LDCs & life expectancy is lower. The
infant mortality rate is lower in MDCs & the life expectancy is higher

The Demographic Transition
1. The demographic transition is a ____process______ with several ___stages___ and
every _____country______ is in one of the stages.
2. Fill in the chart below with characteristics describing each stage in the
demographic transition model (CBR, CDR, NIR, etc.). Characterize the amount of
growth of each stage (low, moderate, high, etc.).
Stage 1
Low Growth
- Agricultural Rev.
- High CBR & CDR
- NIR was zero
- Population was
unchanged
Demographic Transition Model
Stage 2
Stage 3
High Growth
Moderate Growth
- CBR drops sharply
- Industrial Rev. in
N. America &
- CDR drops slowly
Europe
- NIR modest
- Medical Rev. in
- Gap between CBR
Africa, Asia, Latin
& CDR narrows
America
- CBR grows
- CDR plummets
- NIR high &
population grows
rapidly
Stage 4
Low Growth
- CBR declines to
equal CDR (both
very low)
- NIR is zero
- TFR of 2.1
produces ZPG

England passed through the various stages of the model on page 59 with Figure 217. Describe a historical event for stages 1 and 2 and a cultural attitude for stage 4.

Population Pyramids
4.
The shape of a
pyramid is primarily determined by what demographic rate?
Crude birth rate in a community
5.
What is the
dependency ratio?
Number of people too old or young to work compared to people of working
age
6.
What age groups are
categorized as “dependent”?
0 to 14 & 65+
What does the
7.
“graying” of a population refer to?
The growing population of older people that places a burden on gov'ts to meet
the needs of adequate income & medical care
8.
What is the sex ratio?
The number of males per 100 females
9.
What types of
countries/regions are likely to have more males than females? Why? LDCs due to
the mortality rate of women during childbirth
Countries in Different Stages of Demographic Transition

which represents the four stages of demographic transition, identify the country and
where it is located which is in that stage and briefly describe how it got to that stage.

Demographic Transition and World Population Growth
11.
How many countries
are in Stage 1 of the demographic transition?
Zero
12.
What portion are in
Stages 2 and 3?
Majority of countries
13.
And in Stage 4?
Very few countries
14.
Identify the two “big
breaks” in the demographic transition and their causes.
1st Break – Drop in death rate due to technological innovation has been
accomplished everywhere. 2nd Break – Drop in birth rate due to changing
social customs has yet to be achieved in many countries
15.
Complete the
following statement: The first break came to Europe and North America as a result
of…the industrial revolution which produced medical advances.
16.
Complete the
following statement: The first break came to Africa, Asia and Latin America as a
result of…injections of medical technologies from Europe & N. America instead
of arising within those countries.

Malthus on Overpopulation
1. Complete the chart below to describe the views and theories of various population
theorists.

Critics of Malthus

- In LDCs there is a wider

Declining Birth Rates
2.
right?
With regard to food production
3.
Where was Malthus
In what way was
Malthus mistaken?
Population growth increased more slowly than food supply
4.
What two strategies
have proven successful to lower birth rates?
Reliance on economic development & distribution of contraceptives
5.
Take notes on
important facts regarding the distribution of contraceptives.
In LDCs demand is greater than supply. Contraceptives more effective if
distributed cheaply & quickly. Use of contraceptives low in Sub-Saharan
Africa. 2/3 of women use them in Latin America & Asia. Contraceptives are
opposed in several religions (Catholicism, Muslims, Hindus).
