Notes on Population

     Here is some information on population and where people live. Two thirds of the world's inhabitant's live in East Asia, South Asia, Southeast Asia, Africa, and Europe. Most people on the planet live in low lying areas, fertile areas, temperate climate, and near a river or an ocean. People don't want to live in areas that are too hot, wet, cold, or high. Places considered too harsh for occupancy have diminished over time, because of advancements in technology. There are three ways to define density they are arithmetic, physiological, and agricultural. The arithmetic way is calculated by the total number of objects in an area, as well as by dividing the population by land area. The physiological way is calculated by the number of people supported by a unit area of arable land. The final way known as the agricultural way is the ratio of farmers to arable land, the way to calculate this is by dividing the population of farmers by arable land area.
