LESSON STARTER
Think of one place in the world where many people live and another one where very few people live. Write them down.
Beside each one write down the reason that they are highly populated or not.

INTRODUCTION
Even though the population has reached over 7 Billion people the world is not yet overcrowded. In fact it is not even crowded.
There are on average, only 24 people to every square mile of land.
• Some areas are much more crowded than this, but there are also a lot of empty areas.
• The world’s population is scattered very unevenly.

WORLD POPULATION DISTRIBUTION
![Page 9: W ORLD P OPULATION D ISTRIBUTION T ODAY ’ S LESSON Title: World population distribution Date:15/10/2015 Aim: To find out about the distribution of people.](https://reader036.fdocuments.us/reader036/viewer/2022062719/56649ec05503460f94bcc27e/html5/thumbnails/9.jpg)
Population Density(people per sq mi)
Population of a country
Area of country (sq mi) =
Population: 298,444,215Area: 3,539,225 sq mi
Population: 127,463,611Area: 152,411 sq mi
= 84 people / sq mi
= 836 people / sq mi

POPULATION DISTRIBUTION
Population distribution is the spread of people over an area.
Densely populated means that there is a lot of people in a small area.
Sparsely populated means that there is very little people in an area.
![Page 11: W ORLD P OPULATION D ISTRIBUTION T ODAY ’ S LESSON Title: World population distribution Date:15/10/2015 Aim: To find out about the distribution of people.](https://reader036.fdocuments.us/reader036/viewer/2022062719/56649ec05503460f94bcc27e/html5/thumbnails/11.jpg)
The population density is very sparse in the areas of the highlands to the North West and North central.
Scotland is most densely populated along the central belt around areas such as Glasgow and Edinburgh.
There are also pockets of high density population in major cities along the East coast, such as Dundee and
Aberdeen.
![Page 12: W ORLD P OPULATION D ISTRIBUTION T ODAY ’ S LESSON Title: World population distribution Date:15/10/2015 Aim: To find out about the distribution of people.](https://reader036.fdocuments.us/reader036/viewer/2022062719/56649ec05503460f94bcc27e/html5/thumbnails/12.jpg)
REASONS FOR THIS UNEVEN DISTRIBUTION IN POPULATION:
Climate Relief Soil and Vegetation Economic Activity Development Standard of Living
![Page 13: W ORLD P OPULATION D ISTRIBUTION T ODAY ’ S LESSON Title: World population distribution Date:15/10/2015 Aim: To find out about the distribution of people.](https://reader036.fdocuments.us/reader036/viewer/2022062719/56649ec05503460f94bcc27e/html5/thumbnails/13.jpg)
THE IMPORTANCE OF CLIMATE
Polar regions
Few people Lots of people
![Page 14: W ORLD P OPULATION D ISTRIBUTION T ODAY ’ S LESSON Title: World population distribution Date:15/10/2015 Aim: To find out about the distribution of people.](https://reader036.fdocuments.us/reader036/viewer/2022062719/56649ec05503460f94bcc27e/html5/thumbnails/14.jpg)
POLAR REGIONS HAVE FEW PEOPLE BECAUSE:
It is difficult and expensive to survive in
such conditions.
Building is very difficult because
of the permafrost underneath.
They are very remote, due to the poor weather and lack of roads and
railways.
It is impossible to grow crops, so food is expensive.
![Page 15: W ORLD P OPULATION D ISTRIBUTION T ODAY ’ S LESSON Title: World population distribution Date:15/10/2015 Aim: To find out about the distribution of people.](https://reader036.fdocuments.us/reader036/viewer/2022062719/56649ec05503460f94bcc27e/html5/thumbnails/15.jpg)
THE IMPORTANCE OF CLIMATE
Very Dry Regions (hot deserts)
Few people Lots of people
![Page 16: W ORLD P OPULATION D ISTRIBUTION T ODAY ’ S LESSON Title: World population distribution Date:15/10/2015 Aim: To find out about the distribution of people.](https://reader036.fdocuments.us/reader036/viewer/2022062719/56649ec05503460f94bcc27e/html5/thumbnails/16.jpg)
HOT DESERT REGIONS HAVE FEW PEOPLE BECAUSE:
Living in extreme heat and drought is unpleasant to most people
It is impossible to grow without irrigation so
food is expensive
They are remote and unlikely to attract industries, so there are few job
opportunities.
![Page 17: W ORLD P OPULATION D ISTRIBUTION T ODAY ’ S LESSON Title: World population distribution Date:15/10/2015 Aim: To find out about the distribution of people.](https://reader036.fdocuments.us/reader036/viewer/2022062719/56649ec05503460f94bcc27e/html5/thumbnails/17.jpg)
THE IMPORTANCE OF CLIMATE
Regions with moderate climate and reliable water supply
Few people Lots of people
![Page 18: W ORLD P OPULATION D ISTRIBUTION T ODAY ’ S LESSON Title: World population distribution Date:15/10/2015 Aim: To find out about the distribution of people.](https://reader036.fdocuments.us/reader036/viewer/2022062719/56649ec05503460f94bcc27e/html5/thumbnails/18.jpg)
REGIONS WITH A MODERATE CLIMATE AND RELIABLE WATER SUPPLY ARE MORE CROWDED BECAUSE:
It is a comfortable climate in which to live.
No extra costs needed in order to cope with the climate.
Farmers have steady harvests from year to year because the climate is reliable.
![Page 19: W ORLD P OPULATION D ISTRIBUTION T ODAY ’ S LESSON Title: World population distribution Date:15/10/2015 Aim: To find out about the distribution of people.](https://reader036.fdocuments.us/reader036/viewer/2022062719/56649ec05503460f94bcc27e/html5/thumbnails/19.jpg)
THE IMPORTANCE OF RELIEF
Relief means how flat or how mountainous the land is.
Which one has the highest population density?
Steep MoutainousRegions
Flat and gentlysloping areas
![Page 20: W ORLD P OPULATION D ISTRIBUTION T ODAY ’ S LESSON Title: World population distribution Date:15/10/2015 Aim: To find out about the distribution of people.](https://reader036.fdocuments.us/reader036/viewer/2022062719/56649ec05503460f94bcc27e/html5/thumbnails/20.jpg)
They are very cold (except in the tropics)
and so living and farming conditions are
harsh.
STEEP, MOUNTAINOUS REGIONS HAVE A LOW POPULATION DENSITY BECAUSE:
It is too steep for roads are
railways, so the areas are remote.
It is too steep on which to build
houses and factories and to use farm machinery,
so job opportunities are few.
![Page 21: W ORLD P OPULATION D ISTRIBUTION T ODAY ’ S LESSON Title: World population distribution Date:15/10/2015 Aim: To find out about the distribution of people.](https://reader036.fdocuments.us/reader036/viewer/2022062719/56649ec05503460f94bcc27e/html5/thumbnails/21.jpg)
FLAT AND GENTLY SLOPING AREAS HAVE A HIGH POPULATION DENSITY BECAUSE: It is easy to build houses and factories.
Farming is more productive because the soil is deeper and machinery can be used.
Roads are railways can be built, which encourages industry.
![Page 22: W ORLD P OPULATION D ISTRIBUTION T ODAY ’ S LESSON Title: World population distribution Date:15/10/2015 Aim: To find out about the distribution of people.](https://reader036.fdocuments.us/reader036/viewer/2022062719/56649ec05503460f94bcc27e/html5/thumbnails/22.jpg)
THE IMPORTANCE OF SOILS AND VEGETATION
Tropical Rainforests Areas with poor soilsAreas with fertile soils
The hot humid climate is uncomfortable in which to live.
Dense forest is difficult to clear in order to build houses, roads etc…
Soils are very poor, once the trees have been cut down.
Crops grow so badly that farms have to be very large for the farmer to make a large profit.
Crops grow very well and so farms are smaller.
![Page 23: W ORLD P OPULATION D ISTRIBUTION T ODAY ’ S LESSON Title: World population distribution Date:15/10/2015 Aim: To find out about the distribution of people.](https://reader036.fdocuments.us/reader036/viewer/2022062719/56649ec05503460f94bcc27e/html5/thumbnails/23.jpg)
THE IMPORTANCE OF ECONOMIC ACTIVITIES
Farming Areas Industrial Areas
Each family needs a large area to make a living (unless the soil is extremely fertile)
Factories and offices take up a small area,
yet provide many jobs.
![Page 24: W ORLD P OPULATION D ISTRIBUTION T ODAY ’ S LESSON Title: World population distribution Date:15/10/2015 Aim: To find out about the distribution of people.](https://reader036.fdocuments.us/reader036/viewer/2022062719/56649ec05503460f94bcc27e/html5/thumbnails/24.jpg)
THE IMPORTANCE OF DEVELOPMENT
Areas with low levels of development
Areas with low levels of development
Farming methods will be poor and there is
little farm equipment, so farms need to be
quite large.
There are a few factories and
offices, as there are not enough skilled workers, managers or money available.
![Page 25: W ORLD P OPULATION D ISTRIBUTION T ODAY ’ S LESSON Title: World population distribution Date:15/10/2015 Aim: To find out about the distribution of people.](https://reader036.fdocuments.us/reader036/viewer/2022062719/56649ec05503460f94bcc27e/html5/thumbnails/25.jpg)
THE IMPORTANCE OF DEVELOPMENT
Areas with high levels of development
Areas with high levels of development
Most people work in offices and factories which need large populations nearby.
