Population Problems And The Demographic Transition Model

2. What will be the future population growth trends for developing countries in the future?

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.

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.

Many things like high unemployment, different cultural traits and the spread of cities have created two totally different countries. The comparison between the two countries further the accuracy of the demographic transition model because it shows the different stages of development. For instance, South Africa has a high birth and death rate while the US has low birth rates and death rates showing that the US is more developed. We can see this by looking at the difference in things like unemployment rate and life expectancy. Overall the US is more developed than South Africa shown by the differences between things like population, culture and

Thesis: The topic of human population growth is an important issue due to its impacts upon people in developing countries, economics, religion, food production, and the environment; without any limitations, population growth can lead to negative consequences, such as famine and environmental destruction, or even positive outcomes, such as potential economic growth.

How have the social and demographic changes of the last century led to the increased growth and aging of the population? Be sure to discuss this in terms of the demographic transition theory.

The demographic transition is a three-stage model of population growth in Europe. In the first stage there is a stable population because birth and death rates are both high. The second stage happens as mortality rates begin to slowly decline, but birth rates stay high. When this stage happens, there is fast population growth. During the third stage, the population is more stable as both birth and death rates are low and are more or less balanced. In more recent years, a fourth stage as been brought on by Anti-Malthusians. During this stage, population shrinkage occurs because the deaths begin to outnumber the births. Europe provides a great example to the theory of demographic transition. After speedy population growth of stage two, Europe settled at stage three with a stable population. It is currently in stage four with a shrinking population. In most European nations there are lesser births than deaths which could ultimately create other social problems.

The majority of developed nations have experienced several profound demographic changes over the last century—notably, an important decline in fertility rates paired with a substantial reduction of mortality, due in part to the changing nature of leading causes of death. In Canada, the total fertility rate was 3.5 children per woman in 1921 and fell to 1.61 in 2011 (Wadhera and Strachan 1993a; Statis- tics Canada 2013a). Life expectancy at birth for both sexes combined rose, from 57.0 years in 1921 to 81.7 in 2011 (Canadian Human Mortality Database 2014). Migration has also become an increasingly important contributor to population growth over this time period. Whereas less than 25 per cent of the Canadian population growth was due to migratory

According to table 1.1, Israel’s population is increasing at a moderate rate. The nation has a Rate of National Increase of 13.33. With a life expectancy of 82.27, Israel’s population is aging, yet not to an extreme extent due to a crude birth rate of 18.48. Israel’s population pyramid does exhibit their birth rate, as a significant portion of the population is generally young. Their population pyramid does exhibit the effect of WWII and the following search for independence as a Jewish state, as the elderly population is lower for a nation of Israel’s status, However, the offspring of Jewish European migrants is seen in the population pyramid along the middle age ranges.

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

For the past two decades a shifting pattern of diseases and health care service has been observed globally as population increase. Epidemiological transition also known as demographic transition, is a model that is used to explain how population growth rates increase and decrease with respect to time and different factors that account into it such as infectious disease, chronic disease and industrialization. “Conceptually, the theory of epidemiologic transition focuses on the complex change in patterns of health and disease and on the interactions between these patterns and their demographic, economic and sociologic determinants and consequences” (Omran, 2005). This model describes the changing patterns of population distributions in four stages: Age of pestile and famine, age of declining pandemic, age of degenerative and man-made diseases, and postindustrial age.

Demographic transition is the process by which a nation/country moves from high birth rate and high death rates to low birth and low death rates as the growth population in the interim (Weeks, 2005). Some of the nations that have gone through this transitions are; Canada, Germany, United States and England. The demographic transition to an industrialized society is harmful to the environment. Industrialized countries also have the largest ecological and carbon footprint comparative to developing/non-industrialized nations. Nevertheless, demographic transitions have some notable advantages. Countries that have gone through demographic transitions have low birth and death rates. Citizens in

In the 1900's the U.S. population growth was increasing rapidly. The diagram shows that there was an age structure of much more younger aged people than older aged people which indicated the population would grow more quickly. In the 2000's the population age structure is becoming more populated with older ages.The population has some small differences between the older generations being slightly higher in numbers than the younger generations, so the growth rate is declining slightly. In 2050, it is projecting the age structure to be very evenly distributed between the older and younger generations which will stabilize the population growth rate to largely remain the same. It shows total populations of both the younger and older generations

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

As the birthrate in developed countries drops well below the “replacement rate” of 2.1 children born to every woman, to somewhere between 1.1 and 1.4 children — the declining population will have severe consequences in the near and distant future. Demographic decline causes anxiety because it is thought to go hand-in-hand with economic decline. With fewer, younger workers to pay the health and pension bills of an elderly population, states face an unprecedented fiscal burden. The dependency ratio of those aged 65 and over to those of working age looks set to double from one-to-four to one-to-two in 2050."
