Chapter 2: Analysis Questions
Explain in arithmetic density, physiological density, and agricultural density and how they are computed.
Arithmetic density is the total number of objects in an area. It is the most frequently used by geographers. Physiological density is the number of people supported by a unit area by a unit of arable land. Both of these densities are needed to make enough food for the needs of the people. Agricultural density is the ratio of the number of farmers to the amount of arable land.
Compare and contrast the health care provided in developed countries and developing countries.
Developed countries have better health care than developing countries. Developed countries have expenditures that grow over fifteen percent, while developing countries have less than five percent. Seventeen percent of children in developing countries are no immunized against diseases.
Explain Malthus's theory on over-population and how critics have responded to it.
Malthus's theory on over population explained that the population was growing much more rapidly than Earth's food supply because population increases geometrically, but food supply increases arithmetically. Critics have had many things to say about his theory. They disagree that population growth is a problem. They think that a larger population growth could stimulate economic growth and production of more food.
Describe in detail the four stages of epidemiological transition.
Stage one is pestilence and famine. An example of stage one is the Black Plague. Stage two is receding pandemics. A pandemic is disease that occurs over a wide geographic area and affects a very high amount of the population. Stage three is degenerative diseases. Stage four is delayed degenerate diseases.
Describe in detail the four stages of demographic transition.
Stage one of the demographic transition is low growth. During this stage there are very high birth and death rates, which means no long-term increase in population. Stage two of the demographic transition is high growth. This stage has declining death rates and very high birth rates.(baby boom) Stage three is decreasing growth. During this stage birth rates decline and death rates also decline. Finally, Stage five is low growth. This stage has very low birth rate and death rates. During this stage there is no increase in population.
Explain how to measure population growth through natural increase rate(nir), be sure to include crude birth rate(cbr) and crude death rate(cdr) in your explanation.
To find the natural increase rate, subtract the crude birth rate from the crude death rate. The crude birth rate is the total number of love births in a year for every 1000 people. The crude death rate is the total number of deaths in a year for every 1000 deaths.
