Welcome to GCSE
Geography!
GCSE GEOGRAPHY
• Edexcel A exam syllabus
• 75% exam/ 25% coursework
• 3 exams taken at the end of the course in Geographical Skills and
Challenges (1 hour), Physical Geography (1hr 15 mins) and
Human Geography (1 hr 15 mins).
• Skills and challenges = map work and GIS and an investigation of
the major challenges facing the planet today e.g. global warming,
deforestation.
• Physical Geography = Tectonics, Water, Rivers and Coasts.
• Human Geography = Population, Settlement, Tourism, Economic
Activity.

World Population Growth
Objectives:
• To know the key terms “population”, ”population growth rate” and
population explosion”.
• To be able to compare growth rates graphically and notice patterns
in different areas of the world
Key terms:
• Population – The people who live in an area
• Population growth rate: is the rate at which the
number of individuals in a population increases.
• Population explosion: the expansion of a human
population resulting from a decrease in infant
mortality and an increase in longevity.
Objective: To be able to
describe the pattern of
global population growth
over the last 200 years
Homework –

questions about
global population

Using historic and future global population
growth describe the overall pattern of global
population growth.
Success criteria:
Data response question
from a graph:
•Say the overall pattern
•Use dates and figures
•Mention notable
examples
•Mention anomalies if
relevant
Using historic and future global
population growth describe the overall
pattern of global population growth.
The overall pattern shows an increase in global
population between 1750 and projected
figures for 2150. Population was under 1
billion in 1750 and is projected to rise to over
10 billion by 2150. Global population has
increased rapidly from the 1950s onwards,
particularly due to the contribution by LICs.
Global Population growth: Model Answers
•
Using historic and future global population growth describe the overall pattern of global population
growth.
The overall pattern shows an increase in global population between 1750 and projected figures for 2150.
Population was under 1 billion in 1750 and is projected to rise to over 10 million by 2150. Global
population has increased rapidly from the 1950s onwards, particularly in LEDCs.
• Using historic and future global population growth describe the contribution made by LEDCs to
global population growth.
LEDCs are responsible for contributing the most people to the world’s population. Rapid rise in population
in these countries since the 1950s has led to a population explosion in this part of the world. By 2150
it is projected that approximately 90% of the world’s population will be inhabitants of LEDCs.
• Using historic and future global population growth describe the contribution made by MEDCs to
global population growth.
MEDCs show steady population growth between 1750 and 2150. The period of sharpest increase was
between 1900-2000. Since the year 2000 population has leveled out and is set to slowly decline from
2050 onwards.
• The world’s population is not growing in a uniform way. Some regions of the world are contributing
more to global population growth. How has the global distribution of population changed since
1800?
• The world’s population is not distributed evenly. For example, Asia is currently home to more than
half the world’s population (approximately 60.8%), this has changed very little since 1800 and is set to
continue until 2050. Oceania has the fewest inhabitants with just 0.2% of global population in 1800
and a projected 0.5% in 2050. Patterns of growth have changed dramatically within Europe for
example 20.8% of the world’s population resided in Europe in 1800. While population in Europe rose
steadily to 24.7% by 1900 since then it has declined rapidly and this is set to continue until 2050
when just 7% of the world’s population will inhabit this area. Africa, on the other hand, has shown
slow growth in population between 1800-2000 but is set to double by 2050.

slowed in MEDCs since 2000 and is projected
to slow further in the future.
