1 Population Density

2 Population Density The population density of a country is how crowded it is. You can work out the population density of an area by dividing the number of people living there by the area of the land (in square kilometres). What is the population density of PEI? Population: 135,294 Size: 5,656 sq. km 23.92 people per km squared

3 Population Density-high and low People do not live evenly spread through the world. Ex: large parts of Australia are very sparsely populated (low population density), whereas areas in the south-east and around Perth are crowded (high population density). The spread of people around a country is known as its population distribution

4 Look at Canada Canada’s landmass is 9,220,970 km2 2013 population 35,158,300people To calculate the arithmetic population density, we divide the population of the country by the area of land Using figures above, that results in population density of 3.8 people per square km. Does that seem right? How many people live in your neighbourhood? What about Toronto?

5 3.8 people per km² (Really?)

6 Physiologic population density This provides a more realistic look at where people live in a country Physiologic density= population cultivated area (km2) For Canada, the physiologic density would be.. – 35,158,300 – 455000 km2 (cultivated land) – =77.27 people/km2 – Therefore, on average, 77.27 people live on every square kilometer of cultivated land in Canada

7 This is a physical relief map of Canada

8 Climate

9 Opportunities and Constraints Opportunities- describe reasons people would want to move to an area Constraints-describe factors that would discourage people from wanting to live in a particular place World population distribution: Text page 187

10 Where in Canada Do people live?

11 The factors that tend to attract low population densities (Constraints) Extreme climate - too cold, hot, wet or dry Extreme relief - too high and too steep Extreme remoteness - places that are difficult to reach Infertile land

12 The factors that can produce a high population density (Opportunities) Moderate Climate Fertile farming land - many, small farms able to support a large population Mineral resources - mines produce jobs, and provide raw materials for other industries Low land - with gentle slopes or flat ground Good water supply Wealthier areas - people will move to where the jobs and money are found

13 An Exercise Compare the countries of Japan and Norway Calculate the population density Based on the physical geography of these two countries.... Explain the population distribution of each country with regard to physical features of the country

14 Norway Japan
