On the map, colour the densely populated areas in red, and the sparselypopulated areas in green.

Compare the reasons for dense and sparse population. Complete a copy ofthe table below, which has been started for you.

There are reasons why an area has a sparse or dense population. The reasons whyso many people live in densely populated places are called positive factors. Thereare negative factors which have made other places sparsely populated.

These are all factors in population distribution. Shade the positive factors in red, andthe negative factors in green.

Some of these factors are opposites, e.g. Lack of investment is a negative factor andMoney available for investment is a positive factor. Find five other pairs of oppositesand complete the table.

1.2 Positive and negative factors


Pleasant climate Lack of investment Industry and jobs Too hot or too cold

Too wet or too dry Poor water supply Dense forest Good soil for growing crops

Good food supply Little industry and few jobs Flat or gently sloping land

Few natural resources Poor transport links Steep slopes Good water supply

Good roads, railways, ports, etc. Poor soils for farming Money available for investment

Natural resources for industry Open grassland for animals

Negative factor Positive factor

Lack of investment Money available for investment

Many different factors affect the way people are spread across the world. Factors such asrelief, climate, vegetation, water supply, raw materials and employment structures can meanareas have a sparse or dense population.

Working with a partner, read the list of features in the box below and say how eachfeature affects population density.

mountain low land very cold very hot dense forest

desert grassland fertile soil very wet no industry

infertile soil very dry coastal no river remote

inland many natural resources transport no transport

gentle slopes few natural resources industry river

high rainfall poor communications warm very steep slopes

The information below lists different types of area around the world and thepercentage of the earths surface that each one covers.

Colour each box on the key with a different colour to represent each area. Using the appropriate colour, shade the correct number of blocks on the grid to

represent the percentage of the earths surface each area covers. When you have finished, all the blocks should be coloured.

The worlds population is increasing at a very rapid rate. Growth is very much faster in thepoorer countries than in the richer ones. Population changes in a country depend mainly onthe birth and death rates.

Study the factors that can affect birth and death rates around the diagram below.

Copy and complete the table below by sorting the factors that affect birth and deathrates into the correct columns. Some factors may fit in more than one column.

Working with a partner, colour the statements for population control in red andagainst population control in green.

In your opinion was the Chinese government right to introduce its one child perfamily policy?

How would you feel if the British government adopted the same one child perfamily policy?
