1. Pick 2 countries that are not included in Table 2-1 (Rubenstein p.51)
2. Using the websites listed below, calculate the Arithmetic, Physiological, and Agricultural Density for each.
How to Find Arithmetic Density:
1. Select a country from the dropdown menu
2. Open the “people” tab (under the map) to find the total population
3. Open the “geography” tab to find the total square kilometers.
4. Divide the total population by the total square kilometers to find the arithmetic density
How to Find Physiological Density:
1. Under the same “geography” tab, find the entry under “Land Use” that says “arable land.” This will be given in a percentage. Multiply the arable land percentage by the total area of land to find the total amount of arable land.
Example: Cameroon has 475,440 sq km of land and 12% arable land.
On a calculator, punch in 475440 x .12 = 57052 sq km of arable land.
(12%=.12, 3%=.03, etc)
2. Divide the total population by the total square kilometers of arable land to find the Physiological Density
How to Find Agricultural Density:
1. Open the “Economy” tab on the same website.
2. Locate the “Labor Force – by occupation” tab.
3. Find the percentage of people involved in “agriculture”
4. Use the percentage to calculate the total number of people involved in agriculture in that country.
Example: Cameroon has 70% of it’s people involved in agriculture. I already discovered the total population is 475,440. So I punch into my calculator: .70 x 475,440 to arrive at 332,808 people.
5. Agricultural density is a Ratio of farmers to arable land. To find the ratio,
Example: Cameroon’s population is 475,440 and it’s arable land is 57,052 sq km.
