Centrality of the Demographic Transition Concept in the Analysis of Change in Human Populations
Population can be defined as the total number of people living in that
particular country at any one time. Population figures change from
year to year due to increases and decreases of people within that
country. These fluxes can be determined by a change in birth and death
rates and also encompasses immigration and migration in or out of a
country. If a particular country has more births than deaths the
population will increase this is also known as natural increase.
However, if I country experiences more deaths than births the
population will decrease also known as natural decrease. Many
countries worldwide have experienced dramatic changes in population
this change in population is known as the demographic transition.
A demographic transition model can be used to view the changing
population of a country over a period of time. The demographic
transition model describes a sequence of changes over a period of time
in relationships between birth rates and death rates and overall
population change. On a demographic transition model it displays both
birth rates and death rates. The birth rate of a country is the number
of live births per 1,000 population per year, and the death rate is
the number of deaths per 1,000 population per year. There are 4 main
stages to the demographic transition model:
1. High stationary
2. Early expanding
3. Late expanding
4. Low stationary
In the High Stationary phase both birth rates and death rates are
high. Many countries went through this stage prior or during the
industrial revolution...

...n identify separate stages which can be globally
recognised by many countries. The demographic model has seen many
countries progress through all the stages of the model therefore it is
still very favourable for predicting how developing countries
population will evolve. The model continues to occupy a central
position as it is very useful for observing dramatic population
change. By using correct data values countries can see how fast their
country’s population is expanding and by observing this can use to
model to enforce policies to encourage or to discourage child births.
For example, countries can introduce family planning and teach about
contraception to help control birth rates. Countries such as China
have used an enforcement policy whereby only one child per family is
allowed to control the booming population.
Gen Y is from Mercury depicts the major character traits of people born within this generation as compared to those born in prior generations. It outlines the parts of Generation Y that are both relished and criticized by outsiders and it lays down a generalized glimpse into the lives of the members of Gen Y. Written by Kit Yarrow and Jayne O’Donnell, the article focuses on some of the most controversial sides of Gen Y and why these characteristics came into play during this generation specifically. It is the firsthand knowledge that both authors bring to the table that makes this article so effective in its purpose.
Population continues to grow and is expected to reach an all time high in future years. There are tons of different reasons for why population is rising so quickly. In document d, it says, "Every second 5 people are born and 2 people die, a net gain of 3 people. This fact from document d shows one reason why population growth is at all time high. Document d, also states "At this rate, the world population will double every 40 years and would be 12 billion in 40 years, 24 billion in 80 years, and more than 48 billion in 120 years." This will create tons of difficulties, like the amount of food and supplies needed for the world, which will make it nearly impossible for supplies to keep pace with the population growth. Document a shows
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.
Humans are very quickly dominating the globe. Today, the human population is around 7 billion people. Humans are populating at a rate of almost 220,000 per day! Humans are rapidly heading towards Earth’s carrying capacity.
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
One of the most important concerns that not only the certain region or country but the whole globe is facing with is the societal aging. Societal aging refers to the “social and demographic process that result in the aging of a population” Aging of the population would impact different aspect of social life. For instance, as the baby boomers aging, the evolvement of those generation in different community would increase. Also, the expectation of better healthcare and ethical issues around the aged people has grown (Morgan & Kunkle 2016: 6).
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.
Passing through the demographic transition increases the ration of economically active to total population. This creates a larger pool of income from which savings and investment can take place.
Growth rate is the rate at which the population changes over a period of time- either increasing or decreasing. It is normally the net difference between crude birth rates, crude death rates and rate of immigration. In essence, it gives the ratio by which the number of persons in a population rises or drops over a certain duration of time against the total number p...
There are three categories of population pyramids; expanding, stable, and contracting. A comparative observation of the 1990 population pyramid for the selected developed countries show a somewhat contractive demographic environment for both male and females. With all countries showing a considerable tapering off after the age bracket of 40 – 44 and relatively average life expectancy levels there on after. They also display signs of a steady decrease in birth rates as the person’s age in the 0 through to 14 age brackets sustain a similar level of people; with the United States being a slight exception as there are signs of an increasing birth rate in the 0 – 4 age column. The 1990 population pyramids for the selected developing countries display an expanding population trend. What this demonstrates is that these nations had a predominately younger population with high birth rates with low life expectancy levels as the population numbers severely taper off from birth. A notable observation of the population pyramids for both developed and developing European countries, and to an extent Australia and the United States of America, is the impact of World War I from the age of 70 onwards. The result has left a significant dent in the male populations and the feminisation of the 70-74 age bracket and onwards as a consequence
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.
Birth order theory has to do with where at in the birth order of you and your siblings are and how
The study of demography and statistics is essential for a nation. Statistical and demographical data provides the history of population growth. To understand the economical condition of a country, it is important to determine population growth rate and immigration pattern (Elliot). The government uses demographical information to determine the total resources needed to satisfy the demand of the total population (“Demographics Driving”). My maternal uncle, Dr. Mohammed Shahidullah, who is the Demographer of the Illinois Department of Public Health said, “The study of population can make a significant impact on the future of a nation.”
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...
As everyone knows, the history of human evolution originated from more than five million years ago (Pickrell, 2006). Human is the most intellective living being on the Earth, even in the developed universe. With the development of human being, the beginning of human started to be discovered. This essay will focus on the evolution history of human being. It will explain three most significant time slices of human evolution.
