Blog Post #33 - Population Density-

     On Friday we took more notes on the powerpoint, but since I had more notes from Wednesday that I didn't include I'm going to put those notes in this blog instead. Density can be computed in up to three ways for a place. The first way is called Arithmetic Density. This is the total number of objects in an area and the way you compute it is by dividing the population by the land area. The second way is Physiological Density which is the number of people supported by a unit area of arable land. Arable land is land that is actually useful. You compute this by dividing the population by the arable land area. The last way is called Agricultural Density. This is the ratio of the number of farmers to the amount of arable land. This is found by dividing the population of farmers by the arable land area.
