The Theory of Demographic Transition
Demography is the study of the components of population variation and change. Death rate and birth rate are two determinants of population change. Theory of Demographic Transition is comparatively recent theory that has been accepted by several scholars throughout the world. This theory embraces the observation that all countries in the world go through different stages in the growth of population. A nation's economy and level of development is directly related to that nation's birth and death rates. Population history can be divided into different stages. Some of the scholars have divided it into three and some scholars have divided it into five stages. These stages or classifications demonstrate a transition from high birth and high death rates to low birth and low death rates. The Theory of Demographic Transition suggests that all nations begin in stage one as underdeveloped, third world nations and through time transition into first world nations. Firstly this theory was developed based on the statistic collected in many European countries. In this theory, birth rate and death rate are considered to be the major factors or demographic events for bringing change in population.
In the early 20th century, two demographers Landry and Warren Thompson tried to describe transition from the stage high birth rate and high death rate to low birth rate and low death rate. O.P. Walker has classified the `Theory of Demographic Transition' into five stages as follows (Raj, H. 2003):
The High Stationary Stage
The Early Expanding Stage
The Late Expanding Stage
The Low Stationary Stage
The Declining Stage

Some people believe that immigration in the 1900’s was a good thing, however, they would be wrong. The United States government should have restricted the immigrants around that time. Some reasons are the population, the taking of new jobs and lowering wages, and diseases spreading quickly. These all factored importantly into why they should not have been allowed in.
I found that there are varying ages of death in each date category, but for the most part, the ages increased considerably from century to century. This, to me, would be a sign of the technology progression that we have experienced and the modern medical discoveries to aid in the healing processes of some previously fatal diseases.
Life expectancy in many parts of the world has increased since 1800 (Life Expectancy by Age, n.d). To understand these changes we can study the demographic transition, the changes in birth and death rates over extended periods of time. The industrial revolution has significantly improved the conditions of humans and in 20th century death rates declined but the birth rates remained unchanged. In many of today’s developed countries both rates have declined; however, in developing countries, while death rates have declined due the improvements of living conditions, the birth rates are still high which has caused a record high population growth (HAUB & GRIBBLE, 2011).
In 2050, Argentina will be in stage four of the demographic transition model. This proposes that the population growth will be approach zero, and Argentina will sustain an unvarying population. Most of Europe, Japan, and the United States are perpetually in stage four. Argentina will then be considered a developed country with most people in the working age group, with a tumbling birth rate. This can be seen in the 2050 graph when the sides of the “pyramid” begin to straighten out or become inverted all together. Eventually in the future, as the birth rate maintains a steady decline and fewer children are being born, pronatalist policies will have to be put in motion. As the population becomes older, there will not be enough working age adults to care for the elderly. This can be seen in the population pyramid of 2050 and even farther into the future when there are more elderly than working age adults. Some policies that can be put into play would be paying for schooling for children or even tax exemptions for each child a couple has. A possible draw back of this policy would be the influx of children that would in turn take women out of the work force leaving a deficit in the working age adults.
The focus of this paper is on the criminal activities of Individual C, who will be referred to as Mr. C. Mr. C, a 29-year-old Caucasian male, faces multiple charges including one count of felonious assault, one count of crack cocaine possession, one count of methamphetamine possession, and one count of breaking and entering. These charges are not isolated incidents but are instead interconnected, all stemming from a single night when Mr. C broke into his neighbor's home out of desperation for money. In this paper, I will delve into the circumstances surrounding Mr. C's actions, highlighting how each charge he faces can be directly linked to one of the theories we've studied in class. I will explore how a single event in his past could have
Population Paradox In the film, Population Paradox, populations of various countries were analyzed to explore the growing or diminishing fertility rates in developed and underdeveloped countries. Some of the analyzed countries included Japan, India and Saharan Africa. The film begins with the country, Japan. Over the decades, Japan has seen a rapid decline in population due to the economic recession that plagued the country in the 1980’s.
The United States Of America is a stage 4 of the demographic transition model; meaning there is a low birth rate as well as a low death rate within the population. Even though our population is the 3rd highest in the world with over 300,000,000 people, according to the CIA world factbook, Americans have 12.5 births per/1,000 people that being said we had about 3,941,109 babies born in the year 2016.(Bakalar 1). One can compare this to brazil’s population which is over 200,000,000 people making them the 5th largest country in the world based on population, Brazil is also a stage 4 country in the demographic transition model. In Brazil the birth rate is 14.1/1,000 people which makes sense when compared to America's 12.5 births when the USA's population has hit an all-time
Major demographic changes happened from the 1960’s through the 2000’s, according to Charles Hill, “As of the late 1960’s four major facts described the demographics: first, U.S. dominance in the world economy and in the trade picture. Second, U.S. dominance in foreign direct investment (FDI). Third, U.S. dominance of large, multinational firms on the international business scene. Fourth, roughly half of the globe were centrally planned economies of the communist world (not surprising they failed so miserably), and was off-limits to western international business.” (2013, p. 16)
Stage one is pre modern which is when the birth rate and death rate fluctuate between each other which keeps population at a low, but stable point. Next is urbanizing and industrializing, at this stage the death rate drops due to better health care, standard of living etc and causes the population to increase quite quickly. Stage three is called mature industrial in this phase the birth rate stays high and the death rate is low so the population still increases quickly due to better technology. Lastly is the post industrial stage where the birth rate drops to the same level as the death rate which causes the population to become steady once again. An MEDC would be in stage four or nearing the end of it where and LEDC would be in the early stages.
Human population growth on this planet has followed a long, slow J-curve shape leading up to a nearly exponential growth beginning around the time of the modern Industrial Revolution in the 1800s (Southwick, ch. 15). As the Industrial Revolution continues to spread to less-developed countries, their population growth is now skyrocketing as increased access to food and medical care raises the standards of living around the world, while many cultures have not yet responded with a lowered birth rate. This scenario is exactly what happened in London in the 1800s, when the pollution and overpopulation of the beginnings of dirty industry were in full swing.
Population growth is the change in population over a period of time. It happens due to a number of factors such as standard of living, cultural factors, and government policies. When the standard of living become better such as the improvement of social conditions ( shelter, sanitation, clean water , health care and etc) death rate and birth rate reduce as more people become inclined to have fewer children. As standard of living increases, there will be more immigrants thus an increase in population. Government policies which encourage people to have lesser or more children also has a significant effect on birth rate too.
The Demographic Transition Model (DTM) shows how the population of a country changes over time. This is explained through changes in both birth and death rates. These changes can be easily seen and mapped between five different stages of population growth, which can be seen in both More Developed Countries (MDC, and Less Developed Countries (LDC) in several ways.
Human population growth was relatively slow for most of human history. Within the past 500 years, however, the advances made in the industrial, transportation, economic, medical, and agricultural revolutions have helped foster an exponential, "J-shaped" rise in human population (Southwick, Figure 15.1, p. 160). The statistics associated with this type of growth are particularly striking: "Human beings took more than 3 million years to reach a population of 1 billion people...The second billion came in only 130 years, the third billion in 30 years, the fourth billion in 15 years, the fifth billion in 12 years..." (Southwick, p. 159). As human population has grown, there has been simultaneous growth within the industrial sector. Both of these increases have greatly contributed to environmental problems, such as natural resource depletion, ecosystem destruction, and global climate change. Also linked with the increasing human population are many social problems, such as poverty and disease. These issues need to be addressed by policy makers in the near future in order to ensure the survival and sustainability of human life.
An increase in human population can influence our economy. Some of the factors that are affected are unemployment, poverty and the restriction of economic expansion. When the population increases, the cost of health, education, and other areas of urban growth are affected. Unempl...
