Global Population GrowthLO: 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.

StarterHow fast is the world's population increasing?What are
the components of the increase? What will the worlds population be
at the end of this lesson?
Population: the people who inhabit a territory or
statePopulation growth rate: is the rate at which the number of
individuals in a population increases. Population explosion: the
expansion of a biological population, especially the growth in
human population resulting from a decrease in infant mortality and
an increase in longevity.
Growth RateThe world's current growth rate is about 1.3%,
representing a doubling time of 54 years. We can expect 12 billion
people by 2054!
Global Population growth: Model AnswersUsing 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 however, the growth has slowed
in MEDCs since 2000 and is projected to slow further in the
future.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 worlds
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 worlds
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 worlds 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?Some continents have
contributed a lot more to global growth than others. For example,
Asia is currently home to more than half the worlds population
(approximately 60.8%), this has changed very little since 1800 and
is set to continue until 2050. Oceania has contributed the least to
global population growth with just 0.2% in 1800 and a projected
0.5% in 2050. Patterns of growth have also changed within
continents since 1800, for example 20.8% of the worlds 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 worlds 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.
Population clock - reviewWhat are the implications of current
and future growth rates?
While Americans grumble about gasoline prices, food riots have
seared Bangladesh, Egypt and African countries.Countries like
China, India and Indonesia have restricted exports and rice is
shipped under armed guard.Right now, there is enough grain grown on
earth to feed 10 billion vegetarians.Many agronomists think the
world could easily support 20 billion to 30 billion people.
