Key Issues
 1)
Where is the world’s population
distributed?
 2)Where has the world’s population
increased?
 3) Why is population increasing at
different rates in different countries?
 4) Why might the world face an
overpopulation problem?
Case Study: Population
Growth in India p.46
 Why
does the Indian gov’t hope that
women will have LESS babies than their
mothers?
 Write 2 more questions about the reading
on your post-it note (at least one should
be able to be answered from the
readign)
Demography
 The

Why do administrators & teachers study the
demographics?

Sparsely Populated
 People
avoid living in extreme areas
(elevation, climate, precipation, etc)
 Ecumene: portion of Earth’s surface
occupied by permanent settlement
 Increased
over thousands of years (Why?)
 ¾ of population live on 5% of Earth’s surface
 Oceans make up about 71% of Earth
Ecumene
Sparsely Populated Regions
 Dry
Lands: 20% of Earth too dry for farming
ex: Sahara
 Wet lands: near Equator of South America,
Central Africa & SE Asia. Rain & heat deplete
nutrients in soil
 Cold Lands: North & South poles: permafrost
 High Lands: mountains are steep & snow
covered. Ex: Switzerland half of land occupied
by only 5% bc of elevation
 Exceptions occur to escape temps & precip
(Mexico City 7,360ft)

Physiological Density
 Number

 Egypt has to support more people off
same amt of land
 Shows relationship of population

 Looking
at the Physiological Density of the
world, which of the 4 most populous
regions of the world has the highest
numbers? What does that mean?
 How does the United States compare?
Agricultural Density



Ratio of number of farmers to amount of
arable land
Why does US have low agricultural density (1
farmer/sq km) compared to Egypt (826
farmers/sq km)?
MDCs have more technology (more efficient)


Fewer people needed to farm
Allows remaining population to work elsewhere
Key Issue 1 Summary
Where is the world’s
population distributed?
 Summary:
Global population is
concentrated in a few places. Human
beings tend to avoid those parts of Earth’s
surface that they consider to be too wet,
too dry, too cold or too mountainous. The
capacity of Earth to support a much
larger population depends heavily on
people’s ability to use sparsely settled
lands more effectively.
Review
 Where
is the world’s 4th largest
concentration of people?
 What is physiological density?
 How can you describe a country with a
lot of arable land a small amount of
farmers?
 What types of regions do people avoid?

What area is an exception?
Review
 How
would you describe a country with a
physiological density larger than it’s
arithmetic density?
 What are the four types of land that lie
outside of the ecumene
