Why is it important to study population
trends in your state, country, and/or
world?
Our subject of the week is
POPULATION!
Our objective is to be able to….
1. Describe trends in world population
growth and distribution.
2. Locate and describe physical and human features
that influence the size and distribution of settlements.
3. Explain processes that have caused change in
settlement patterns.
Population Vocabulary
Birthrate
Fertility Rate
Infant Mortality Rate
Push/pull factors

Population distribution
Death rate
Population Pyramid
Population Density
Rate of natural increase

Geographers study the
relationships between populations
and their environment.
Notice a familiar
theme????
Geographers study the relationships between populations and
their environment by using…
MAPS
Cartogram Maps
TEXAS
GRAPHS
Population Pyramids
Powerful predictors of the future VIDEO
Demography
The statistical study of human
populations.
Demographics
Statistics (information in
number form) about human
populations.
How can studying demographic
statistics be useful?

Population Density:
Average # of people per square mile.
In the United States we have about
300 million people and 3,717,792
square miles.
What is our population density?
About 81 people per square mile
Canada’s population is about 32
million and they have 3,851,788
square miles.
What is Canada’s population density?
About 8 people per square mile
Monaco is a microstate in Europe on the
Mediterranean coast bordering France and
Spain. It’s population is about 33,000 and it
has .75 square miles.
What is Monaco’s population density?
About 44,000 per square mile!
Egypt has a population density
of 180 people per square mile,
but since 90% of the country is
desert, most people live along
the Nile River.
Why?
Arable land:
Land that can be farmed.
Measured in arable land,
Egypt’s population density is
about 9,000 per square mile.
So…what does population
density actually tell us?
An AVERAGE!!!
Can you think of a different way to figure
the population density of a country?
Physiologic density—just takes into account arable land
square miles and divides
Population Distribution
• 90% of the world’s people live in the
Northern Hemisphere.
• 2/3 of those people live between 20’-60’
North (what latitude region???)
• many live in low-lying areas, particularly
along fertile river valleys near the edges of
continents
NOTE:
POPULATION IS NOT
EVENLY DISTRIBUTED!
TRENDS IN WORLD POPULATION
Where was population first
distributing in world history?
TRENDS IN WORLD POPULATION
Culture hearth: A place in which
important ideas begin and thereafter
spread to surrounding cultures.
Ancient examples:
•
Mesopotamia (Fertile Crescent)
•
Egypt
•
China
•
Olmec, Teotihuacan, Maya
•
Indus River Valley
Make an observation
*Where are these places?
*What is it like there?
*What is the population
density today?
Draw a conclusion from
this information.
Let’s review!
1. What is the statistical study of human populations?
2. Why do people study population geography? How is it
applied in the “real” world?
3. What three things does population density reflect about
a country?
4. Why is the world’s population so unevenly distributed?
5. What terms are associated with population change?
