1. Population Q.1 Densities The measures of Density help geographers to describe the distribution of comparison to available resources.

2. Arithmetic Density  Total # of people divided by total land area  AKA Population Density  Density varies even within a country…some areas are more condensed while others are sparsely populated.  Enables geographers to compare the # of people trying to live in a given piece of land in different regions of the world

3. Find the Arithmetic Density  Country 1:150 million people and 6 million square miles  Country 2: 380 million people and 6 million square miles  Country 3: 800 million people and 60 million square miles. Which country is more sparsely populated?

4. Physiological density  # of people supported by arable land  High density the greater pressure that people may place on the land to produce food  Gives insight to the relationship between size of a population and resources

5. Comparing Physiological and Population density  Helps understand the capacity of the land to yield enough food for the needs of the people.

6. Agricultural Density  Ration of the # of farmers to the amount of arable land.  helps account for economic conditions  MDC’s have a lower Ag. density
