This document discusses globalization, population change, and migration. It covers several topics:
1. Population growth has been exponential over the last 100 years, with the global population now over 7 billion. Asia and Africa currently have high growth rates, with China at 1.3 billion and India at 1.2 billion people.
2. Population change in a country is driven by natural change (births minus deaths) and migrational change. Migrants bring their cultures and help mix societies. Push factors drive people from areas, while pull factors attract people.
3. The Demographic Transition Model explains how countries transition from high birth/death rates to low rates as they develop. It shows changes over both time
3. Globalisation, population change
and migration
1. Know how globalisation has effected
population
2. Understand how globalisation has
led to population change
5. Population Growth
• Exponential growth in last 100 years.
• Globally population is over 7 billion now.
• Asia and Africa currently have high rate of
growth.
• China has 1.3b and India has 1.2b.
• Population growth puts pressure on resources
in that area. E.g. China now has to import raw
materials from …………………….

7. Population Change
• Any population can change due to two factors;
…………………………………… and ………………………..
• Natural change is the difference between the
birth and death rate. It could therefore be
negative as well as positive.
• Migrational change could also be positive (UK)
or negative (Poland) for a country.

8. Factors affecting Migration
• Migrants take with them beliefs, cultures and
help to mix societies so are a key element of
globalisation.
• Push factors help to turn people away from an
area (e.g. ………………………………………………………)
• Pull factors help to pull people into an area
(e.g. …………………………………………………………)

12. Population growth over time
• The Demographic Transition Model
• The Demographic Transition Model (DTM) is a
model used to explain the transformation of
countries from high birth rates and high
death rates to low birth rates and low death
rates as part of the economic development of
a country from a pre-industrial to a highly
industrialised country.

13. The DTM continued …
• It is based on the American demographer
Warren Thompson’s prior observed
changes, or transitions, in birth and death
rates in developed economies over the past
200 years.
• It shows;
– 1. Change over space – different countries are at
different places on the DTM
– 2. Change over time – a country should progress
through each stage of development over time.Globalisation, population change and migration
17. Population Pyramids
A population pyramid is a graphical illustration showing the
distribution of various age groups in a population which normally
forms the shape of a pyramid.
Here is an interactive one for the UK
