Arithmetic Density tells us the amount of people living in a certain area. This could be helpful because this density shows the growth rate through out the whole world which could help people who have a high population make sure that they are getting what they need which could be from water to food to the basic needs,
Physiological density means the number of people per unit of area of arable land. This could be useful to geographers because it can give them a rough estimate of how much food is being produced in an area and how many people it really needs to feed.
