lems in the countries and populations on a global scale. In discussing regional variations and patterns of population growth many components are involved. Fertility rates and death rates are good indicators to the global population and patterns of growth and variation. Total fertility rates (TFR) is the best prediction of a population over time. When we look at these numbers one, may start to wonder what factors have influenced these patterns and variations being observed. There are many factors that impact a population. To start one can look at the five themes discussed throughout our book, which include, culture region, cultural diffusion, cultural ecology, cultural integration, and cultural landscape. Each one of these themes discussed in chapter one can provide answers as to what factors influence population growth and variation. Ones culture region can play an important part in determining both birth and death rates. Cultural diffusion also provides insight into variations and changes in a population on a global level. Cultural ecology provides one with answers to population growth and variation based on a populations physical environment. Cultural integration can explain why certain patterns are observed in population growth and variation across the globe. Lastly, ones cultural landscape plays an important role in determining variations of a population. In the article titled, Before the Next Doubling, one can see that the doubling of the population is often due to many factors, which were discussed earlier. The article makes point of some of the causes of population growth, which include an unmet demand for family planning, a desire for large families, and population momentum. The article discusses the reasons to each of these causes. There is an unmet demand for family planning in a large percentage of the world. There is also a desire for large families if many areas such as Africa where many children die fr...
