GLOBAL POPULATION TRENDS

Population Predictions

• Each student must make a prediction on the following population features:

1. How many more people are born into the world by the end of this class?

2. How many people have died in the world by the end of this class?

3. How many more people will be infected with the HIV virus by the end of this class?

4. How many pounds (lbs) of garbage will be dumped into the sea by the end of this class?

5. How many hectares of forest will be taken out by the end of this class? 1 hectare = 2.5 acres

• Write your predictions down. We'll check back in an hour

Population Density

Density is the number of people living in a unit of area. Typically measured per square km.

For example, based on 2016 stats, Canada has…

a population of 36, 730,000. 9,984,670 km2 of land within its borders Population density of approx. 3.7 people per km2

The United States has a population density of 35 people per km2

Population Density

By Comparison: Other notable countries…

India has a population density of 368 people per km2

Shanghai as a density of 3700 people per km2

The highest in the World is Manila, Philippines at 41,515 people per km2.

The 3 Smallest in the World are:

Greenland with 0.026 people per km2

Falkland Island with 0.26 people per km2

Mongolia with 1.9 people per km2

Population densities can be misleading for large countries such as Canada, where a large portion live in a small area (in our case, along the southern boarder)
