Class Post 11-8-18

Today in class we went over the Cultural Landscape. The main questions that we are giving and we will be reviewing over the unit are: "Where is the world population distributed?", "Why is global population increasing?", "Why does population growth vary among regions?", and "Why do some regions face health threats?". Part of Cultural Landscapes are the population concentration. One fact about population concentrations are that 2/3 of the world's inhabitants are clustered in four regions: East Asia, South Asia, Southeast Asia, and Europe. Another part of Cultural Landscapes is population density which is separated into three different parts: Arithmetic Density, Physiological Density, and Agricultural Density. The arithmetic density revolves around the total number of objects in an area. The physiological density revolves around the number of people supported by a unit area of arable land. And lastly, the agricultural density revolves around the ratio of number of farmers to amount of arable land. The last thing that we went over today in class were the components of population growth. This includes the Crude Birth Rate, Crude Death Rate, and National Increase Rate. To get the NIR you have to subtract the crude birth rate and the crude death rate.
