SIGNIFICANT RELEVANT POINT (SRP)SIGNIFICANT RELEVANT POINT (SRP)
A Significant Relevant point is simply one or two sentences which contain factual information that is relevant to the question asked
An SRP may be a statement or a geographical term
A statistic may also be counted as an SRP*
You should always draw labelled diagrams in the physical geography questions where appropriate
SIGNIFICANT RELEVANT POINT (SRP)
1 SRP = 2 marks
There is a limit of 2 statistics for each answer
If you are including diagrams they must display information that has not previously been described in writing!
Elective Unit 5:
Chapter 1 Measuring Population (11 classes)
Looking at population characteristics change over time and space
Chapter 2 Overpopulation & Development (11 classes)Looking at how population characteristics have an impact on levels of human development
Chapter 3 Migration (8 classes)
Looking at how population movements have impact on the donor and receiver regions
Core Unit 3:
Aims
This unit will examine the dynamic nature of population and the pattern and distribution of settlement.
The Unit is structured under two sub-heading
The Dynamics of Population
The Dynamics of Settlement
*This unit will have links with Core Unit 2: Regional Geography
Chapter 1:
Measuring Population
(Pages 5-25)
Learning Outcomes (i.e. what you need to know for the exam)
Explain:
Explain the term dependency ratio and how to calculate it
Explain the changes in growth patterns-
With a focus on Ireland and France
Key Term
World Population
However, the rate of increase is not evenly spread:
Developing Economies=rapid population growth
Developed Economies=slow growth
Current Population Clock
seven billion thirty-six million eight hundred fifteen thousand five hundred ninety-two 21:00 UTC (EST+5) Sep 02, 2012
Future trends in world population
Low Prediction: will occur if efforts to reduce birth rates across the world are successful in all regions
High Prediction: will occur if efforts to reduce population growth are unsuccessful
Medium Prediction: Current world trends indicate that the medium prediction is most fitting as efforts to reduce birth rates in India and China are taking effect
To recap....
Is this population growth even?
What is population growth like in:
Developed Economies?
Developing Economies? Why?
What was the world population growth like in the 1600’s, 1700’s-1800’s, 1950’s- now?
What does demography mean?
Population Distribution and Density
Population distribution and density
Population Distribution means the spread of people across the world
Population Density is the average number of people living in a square kilometre of land.
It is related to the population and land available.
Population density is calculated by dividing the population by the land area.
Re-cap....
What is happening to the world’s population at present?
What is the population growth like in: (a) developed economies (b) developing economies
What was the world population growth like in the 1600’s, 1700’s-1800’s, 1950’s- now?

What does population density refer to?
How do you calculate population density?
Population
Factors effecting population distribution and density
Physical and human factors affect where people live (distribution) and how many people live in a region (density).
Physical factors.....
1. Climate: affects where crops can grow successfully.
Areas with temperate climates have higher population densities than regions with hot or cold climates.
Over 90% of the world’s population live in the northern hemisphere’s temperate zone. Temperate climates have no extremes of temperature or rainfall making farming and settlement easier.
Temperate regions (e.g. Europe and North-East USA) are densely populated. Whereas, desert equatorial and arctic regions have fewer people.
2. Relief:
Plain), tend to have
easier on flat land.
in altitudes below 500m.
Mountainous regions (e.g. The Alps) with cold temperatures, high steep grounds, strong winds and snowfall have low population densities.
In hotter climates (e.g. tropical and equatorial regions) people favour coastal regions as they are cooler.
3. Soils:
soils(brown earth, boulder clay) suitable
for growing crops
Mountainous regions tend to have thin, infertile or no soil.
4. Drainage:
populated than areas without water.
Rivers provide fertile alluvial soils for
farming as well as a mode of transport.
In the past rivers served as a defensive
feature.
Mature river valleys are low lying which encourages farming and settlement (e.g. River Ganges in India and River Rhine in Europe.
5. Resources:
than areas with few resources (e.g. Sahel
of Africa).
supplies attract industry
distribution of people to unfavourable
regions. For example, settlements in desert
regions in central Australia only exist because
of gold mines. Large settlements can also be
found in northern Sweden where iron ore.
