Part A) Demographic Transition Model
1)
• In Stage one, birth and death rates high, but have a low total population due to the high death rates.
• In Stage two, the birth rates take a very minor dip in the graph, but maintains its birth rate. The death rate is decreasing due to increasing amounts of knowledge towards medicine as time goes by. The total population is increasing due to the death rates decreasing.
• In Stage three, the total population is increasing at a greater rate than in the previous stages. The birth rates and death rates are decreasing because of many factors in society, but the most prevalent factor is due to the increase use of birth control.
• In Stage four, the population is increasing, and is soon approaching

This Pyramid is similar to Stable Pyramids, but has a lower birth and death rate. Contracting Pyramids have slightly longer life expectancies, and has an older average population in comparison to the Stable Pyramid.
Part D - Population Distribution, Consumption and Sustainability
a) At the current world population growth rate, I believe there won 't be sufficient resource to help support this rate due to limited resources such as water, farming area, housing, etc with our current technology. However, I do believe that after a breakthrough in technology, there would be more population growth in the world, but would slowly come to a point where it simply can’t sustain any more and this cycle would go on until technology stops advancing. It is difficult to maintain this at a constant rate without decreases at any point with the expanding number of people while Earth has only finite resources. Theoretically though, if we were to able to constantly increase efficiency with our land space, and colonize other planets, the population of the human species would always increase.
b) The world population is not equally distributed. There are few countries that have high population densities. Places situated on the coast have good climate conditions for vegetation, which is the reason why there are usually high population densities situated on the coastline in population density geographical maps.
c) There are many key things that determine population density in a certain area.
The first period was a very long period of time where the rate of population growth was very low. The second period was a shorter period of time that lasted up until about 1962 and it had a large increase in population growth. Finally the third period is the current period and it is where the population growth rate starts to decrease. The decrease in the population growth rate is due to the improving living and health conditions. Another reason for the growth rate going down is that parents, families, and other people are becoming more aware of the increasing population and the dangers or hazards that it will bring.
In developed countries the birth and infant mortality rate is lower than developing countries. With the developing countries having a higher birth rate they also have a higher infant mortality rate. It is difficult to predict the earth’s population growth because of the different stages a country might be in, or how fast they move from one to another. Stage one is preindustrial, this is when the birth rate is high but so is the death rate so the population is low. Stage two is the transitional stage where the birth rate is still high but health care has gotten better so the death rate has decreased and the population is skyrocketing. Stage three is the industrial stage this is when the birth rate is still increasing even though the death rate has stayed the same making the population still increase. In the final stage postindustrial the birth rates are very low because of birth control and people desiring smaller families. The death rate is still how and the population slowly
There is a very low infant mortality rate, 2.8 in a thousand, and a relatively low birth rate as well, at 7.41 births in a thousand. However, the death rate, 9.83 deaths in a thousand, is
The Medical Revolution was a period of time where medicinal technology in Europe prevented the deaths of thousands of citizens. This marked the shift from Stage 2 to Stage 3 of the demographic transition model, as crude death rate significantly decreases. The natural rate of increase also increases, while the crude birth rate does not
As the human race continues to grow older the population starts to grow. Population growth is a change in the size of a population over time, depending on the balance of births and deaths over a period of time. For the world, population grows when the amount of births exceeds the amount of deaths. As shown in figure 1, the world’s population grew very slowly until about 1750 that is when the population growth started to increase rapidly. Figure 2 shows the growth of the global population from 1950 onwards, it also shows the projected population growth up to 2050. The global population is estimated to rise to approximately 9 billion people by 2050.
b) The graph below illustrates the actual and projected population shares of those of middle age (40-64
My best guess is India will have the highest population density because they are industrializing quickly, have plenty resources and are working to get more and also they have lot of job opportunities. In other places it does seem like there will be much industrialization such as Africa which can cause the people to die out when they do nt have resources. Also the culture in India from what I have seen is that people have many children and encourage big families and take care of each other.
Dictator Pol Pot held goals of attaining independence in Cambodia. He was also determined in making both social and economic reforms in Cambodia. However, he did not achieve his goals. This was due to his fall in the year 1978. The effects of his poor leadership were the major causes of his fall. Based on the behaviorism approach, a leader should portray good characters that are beneficial to his people. Good behavior is rewarded while bad behavior is punished (Chandler, 1999). Therefore, his behavioral consequences were punished because he failed in his leadership. Due to his harsh and brutal leadership, revolts were made against him. As a result, he lost power before achieving his goals. Therefore, good leadership traits and behavior would lead pol to achieving
The first stage; age of pestilence and famine is characterized by high fluctuation of mortality rate and birth rate. McLeroy and Crump (1994) stated “…..is characterized by high deaths rates, endemic diseases, chronic under nutrition or malnutrition, and periodic epidemic of infectious diseases and famine”. Due to this, population growth was really slow and this stage is considered as a stationary phase. High birth rate was due to all the factors associated with high fertility such as lack of family planning education, child bearing age, and
The demographic transition has been closely accompanied by an epidemiological transition in the area of health, that is, a change in the profile of morbidity and mortality by cause, and the distribution of deaths by age. This transition is apparent in the percentage reduction in deaths caused by transmissible (respiratory, infectious and parasite–borne) diseases and in those in the perinatal period, giving rise to a relative predominance of deaths caused by chronic and degenerative diseases (of the circulatory apparatus and malignant tumors), as well as external causes (caused by violence, accidents and injuries). This reflects both the greater drop in mortality for the first group of causes, which mainly occur in children, as well as by the
Guatemala, the most populous country in Central America, is a textbook example of a country firmly in stage 2 of the demographic transition model. A country steeped in rich culture, Guatemala still has a sizeable population of Mayans, the ethnic group that populated the geographical region pre-colonization. This minority is often the victim of marginalization, much like the Native Americans of the United States. This, combined with the pressures of a rapidly increasing population, create many complicated issues for the country to deal with as its next generation comes of age.
Global population; it’s what has been mystifying and engaging our human geographers for centuries. In fact, the various stages of the demographic transition have shown what the population is acting as now, and how it will change in the future. Starting right here in the United States, we are having a very successful time maintaining a small growth population. Our 1.83 child per woman ratio is slightly below the zero growth 2.03, but our population continues to grow because of our governmental decision to approve immigration into the country. Because of this vital decision, it allows our population to continually grow. Now, back to the demographic transition stages. The United States is currently in Stage 4 along with many other Developed European
With the introduction of agricultural and the rise of the Industrial Revolution, living standards have been elevated, while epidemics and famine have been diminished (prb.org). Ever since the 18th century, the human race has only continued to make improvements. For example, in the medical field. The creation of vaccines, medicine, and an increased knowledge of the spread of diseases have all helped to eliminate common causes of death, leading to overpopulation. Not only is overpopulation caused by an accelerated number of births, but it is also due to a decrease in the number of deaths, with 360,000 people are being born every day and only 151,600 deaths a day
2,000 years ago the world, in terms of population, was only the size of the United States of America, 300 million people. Today, the world’s population is at seven billion and counting. If the population rose at a steady rate from year 0, we would’ve reached 1 billion people by about 210 A.D. This, however, was not the case. We reached 1 billion people in 1800 A.D, which means that there had to be very odd growth periods for the population as a whole REWORD ME. From 0 to 1000 A.D. the population only rose about 10 million people, “and well into the second millennium, [the population] grew less than 0.1 percent each year” [1]. However, from the year 1800, with 1 billion people worldwide, to 1930, the world gained another billion people. We then reached three billion people in 1960, five billion in 1987, and 7 billion in 2013. One can clearly see that once we entered the 19th century, the world’s population started growing like a 14 year old boy going through puberty; rapidly, and without any warning. One thing that can explain this growth is called the Demographic Transition.The Demographic Transition is a theory that explains the growth.
But the death rate exceeds the birth rate, which triggers the population increasing very slowly or almost stable. In this stage, birth rate becomes high due to less use of contraception and sterilization. Most of the people do survive in agriculture where the children are considered as economic assets and so people are encouraged to get many children. Similarly death rate becomes high due to diseases, natural calamities, wars, etc. Infant death rate is also found very high. Because of poor health facilities provided by the state to the people, lack of clean water and sanitation and food shortage, health of the people will be weak so that the people will depart the life in high numbers. Before 1920, China and India were at this stage (Raj, H. 2003). This stage is generally found in the countries where people depend on agriculture as a main source of surviving. At present, the countries like Nigeria, Ethiopia, Tanzania, Angola, etc. are passing through this stage (Raj, H.2003)
