Population Density
Learning Objective:To define the term population density and understand the key terms To use key terms to explain the population density of a number of
places around the world

This is a square kilometre and is how population density is
measures.

This is the number of people living in a square kilometre
What is population density?
Sparsely populated Densely populated
Least populated Most populated

So what does population density look like on a map?

Population Density Positive Factors Negative Factors
Your task:
In your books divide your page into three columns:
There are 10 images around the room. Fill in the table in your book to describe the picture as Sparse or Dense and suggest some positive and negative factors for each picture.
