In such a massive country, farm size varies radically depending on what is grown, where it is grown, and what type of farm it is. The study of population is important to anyone who is going to take the AP Human Geography Exam. Agricultural density is found by dividing an area of farmland by the total population of farmers in the same area. In 1971, Bangladeshi farms on average produced around 90 pounds of rice per acre.

The largest cluster of people on Earth live in East Asia, with about 20 percent of the worlds population residing in that region. Laborers on these farms, and other local people, thus may have little to no access to the food produced. In this AP Human Geography study guide, we will explore the concept of population density as a sub-set of demography, which is the study of the characteristics of a human population.
