1 List the factors that influence population distribution. What aspects influence each of the factors? Identify the most and least populous continents. How many millions of people inhabit each continent? What percentage of the world population lives on the most populous continent? Compare. Is absolute population the same as population density? Explain your answer. K E Y Q U E S T I O N S Population density Countries that have many inhabitants are not necessarily densely populated . This i s because population density relates the number of inhabitants, or absolute population, to the size of the territor y. Therefore, if many people live in a small territor y, the population density will be high . If the same number of people is spread over a much larger territor y, the population density wil l be low. Population density tel l s us the number of inhabitants of a given territor y per square kilometre of sur face area . (3) Your turn Explain what the map shows. To which territorial unit does the data correspond? Look at the statistics in your atlas. Are the most densely populated countries the ones with the highest number of inhabitants? Name five countries with low population density. Explain why you think this is. Interpret a population density map A choropleth map is used to show population density by countr y. These maps use different shades of colour to represent the spatial distribution of a variable. Higher values of the variable are shown with darker colours. The values are grouped into ranges, and the colour of each range is applied to a specific territor y.
