Population Geography
What does population mean?
The total number of persons inhabiting a country, city, or any district or area
Population
Learning Objective
- To identify what population means and the impact on the World.
What 3 questions would you
like to answer
from the graph.
1. Annotate (label) the graph with
description of what has/is happening.
2. Now suggestion why you think it has
happened.
The World Population
• What is the World’s Population?
• Is the World’s population increasing or decreasing?
• Draw a cartoon to describe the change in the World’s population.
• Research either on the Internet or through books:
What is the population of the USA?
Bring it in for next lesson Make sure you note when this figure was from &
where you got the information from.
Population
Learning Objective
- To identify what population means and the impact on the World.
The population of the United States is
approximately 314.69 million.
US Census Bureau 11/12
The population of Florida in 2011 was
19,057,542, ranking 4th, . Marion County
332,529

Population Change
Learning Objective• To identify what natural change is and the
factors that influence it.
Create your own image to explain the
Natural change in
Population
What influences Population?
Birth Rate Death Rate1. The ratio of total
live births to total population in a specified community or area over a specified period of time
2.
1. The ratio of total deaths to total population in a specified community or area over a specified period of time
2.
What changes Birth and death rate?Change Does it increase or
decrease the birth or death rate?
How does it change it?
Better Healthcare
A terrible war
Clean water is available
More women working
More healthy food is available
Deadly disease spreads
Birth control is provided
Think about the US’s population........
Do you think the population is increasing or decreasing?
Media Reports might make you think it is increasing, but it actually is decreasing.
Why do you think the US population is decreasing? Link your answer to the birth
and death rate.(Remember to gain the higher levels you need
to explain Why, How and use examples!)http://www.youtube.com/watch?v=fnipbr-SRKM
Do you think the population is increasing or decreasing??

Population Density
Learning Objective- To learn why some places are densely populated
while others are sparsely populated.
Why are some places really crowded and others not?
What’s the density?
Some areas of the world are more populated than others.
We use population density as a measure of how many people live in a set area.
Population density is measured in people per square kilometre (km2).
Population density = Number of people/Area(km2)
India has a population of 1,103,371,000 and covers 3,287,263km2. The population density of India is 336.
What is the population density of Florida?
The population is 19,057,542
Florida covers 170,305 kilometres squared.
Population density = Number of people / Area(km2)
111.90 is the
population density of Florida.
High Density (densely
populated)
Low Density(Sparsely
populated)
Task Create 2 top
trump cards for why countries or areas would be
densely and sparsely
populated.
Where would you prefer to live in a densely or sparsely populated
place ?Why?
Homework
• Using the website above write down 5 of your favourite facts and tell me why you like it.
• For example. I like this fact because it shocks me how much
logging occurs in the World as the rainforest is very important to the wildlife and humans.

Population Density
Learning Objective- To learn why some places are densely populated
whilst others are sparsely populated.
Do the factors
increase or
decrease natural
change?
Lack of birth control/family planning
Famine causing lots of people to die due to lack of food
Parents wanting lots of children to help provide an income (such as working on
farms)
Disease (for example HIV/AIDS) causing lots of
people to die.
In many rural areas it can be the tradition to have lots of
children
Many young children die due to poor health care
No education about the benefits of a smaller family
War/Conflict
Government policies which want to strengthen their
population
Drug use, alcoholism and sexually transmitted diseases
(STD’s) is blamed for this change in .
Better health care Lack of resourcesPeaceful conditions within
the countryGovernment policies (such as
the One Child Policy in )
A culture which means men have a high status for having lots of children
Education about the benefits of a smaller family
Population Distribution
To investigate the population density of the US.
Density vs distribution
Density figures only tell us how many people live in an area.
The population can be evenly spread.
Often, distribution of the population is affected by factors of physical and human geography.
To describe the way people are distributed around an area we need to talk about the population distribution.
Alternatively, the population can be randomly distributed.
The population can also be clustered around one specific location.
When describing population distribution there are guidelines that should be followed.
Describe the obvious pattern. Where do most people live? What areas are most populated?
Give figures, if available, and locations. Using accurate figures helps support your description.
Give any exceptions to the ‘obvious pattern’. Are there areas that do no fit in with the general population distribution?
A choropleth map is a very accurate tool to use when describing population distribution.
Describing distribution

2000 U.S. population density within each county (by parish in Louisiana), in persons per sq. mile (lower 48 states only): Light to dark (yellow to blue): 1-4 (y), 5-9 (lt. green), 10-24 (teal), 25-49 (dk. teal), 50-99 (blue-green), 100-249 (blue), 250-66,995 (dark
blue/purple).
Group Task For the Choropleth map state 3 facts about
the pattern of population distribution in the US.
To reach the higher levels include: - Values e.g it is 2.5 – 6.3% - Compass Directions- Towns and Major cities (use an atlas to help you)
Population Distribution

In the World come up with 3 ...

the World
Sparsely Populated areas in
the World
World Population DensityLearning Objectives-To explore areas in the world where there is a
dense and sparse population density.
Reminder Population Density
• People are unevenly distributed around the world. The difference in distribution is measured
by comparing population density - the number of people per square kilometre (km²).
• Population density is determined more by environmental factors which make an area more or less attractive to settlers than by economic development.
• The way in which people are spread across a given area is known as population distribution.
• Patterns of population distribution tend to be uneven. For example, in the US there are more people living in Florida and California than Montana and Wyoming
Reminder Population Distribution
World Population Density – by countryWorld Population Density – by countryWestern Europe and Asia are densely populated
North America, South America and Africa have a low population density
Out of every 100 persons added to the population in the coming decade, 97 will live in developing countries.

Population Pyramids
• To explain what Population pyramids show us and how they may differ.
The Birth Rate , Death Rate and Life Expectancy
all affect the population structure
of a country.
What is this? What does it tell us about the population of a
place?
What is a population pyramid?• Population structure can be shown as a population
pyramid.
Features of a population pyramid.-Population is divided into 5 year age groups.-Population is divided into males and females.-The percentage/Number of each age /sex group is
given.
What can we find out from PP’s?
How would the population pyramid look if it was a developing
country (LEDC)?
Match the key words with the definitions
Population density
Is when there are relatively few people living in one area
Under/optimum population
When the number of people living in an area exceeds the amount of resources needed for them
the balance in population needed with the number of available resources
Sparsely populated
The number of people living within a given area
Population distribution
overpopulation
means the way or pattern in which people are spread across the world
