Introduction
This assignment talks about The Introduction to Demography, mainly on the topic Demographic Transition. This assignment cover topics like the meaning of Demographic Transition, how fast the world’s population is growing even though the growth rate is slowly declining.
There are also many factors affecting the population of different countries, but this assignment covers the Cultural Factors such as the Religion and people’s believe that affect the population of different countries in the world.
This assignment also covers in detail about the different phases in demographic transition as there are five stages and how birth and death rates affect in each stage. It contains graphical illustrations of each stage for better understanding

This is interpreted through a demographic transition model (DTM). The theory is based on an interpretation of demographic history developed in 1929 by the American demographer Warren Thompson (1887-1973).
The world’s population growth
Anthropologists believe that the human species dates back at least 3 million years. They say that our ancestors lived as hunters and gatherers and therefore, the population was less than 10 million.
However, as agriculture was introduced, communities evolved and supported more people, which in turn helped in increasing of the population.
The world’s population increased by about 300 million as of A.D 1 and continued to increase at a moderate

Conversely, some cultures and religions discourage large families which affects in the decrease of birth rate.
• Some religions like Christianity encourage education which inversely leads to civilised thinking amongst the people and leads to lower birth rates. However, some religions such as Muslim are strongly against women getting educated and therefore they have large families which lead to high population growth rate.
• Countries with a high literacy rate show lesser growth of population than a country with a lower literacy rate. A high literate country’s people know about family planning and the good points of having a small family. They also get married late. All these results in a declining population growth rate.
• The social status of women also affects the rate of population growth. Women who belong to the higher status in the society seem to marry later in their age whereby reducing the birth rate. Women who belong to the lower status in the society tend to get married faster thereby producing more number of
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
1. Demography is a discipline in Ecology that deals with population measures such as, age, size and overall structure are critical to demographic work. Demography is used to help understand a populations growth pattern, although not all individuals are the same age and size or have the same survival and birth rates. Demography allows for greater depth and detail of a populations structure to be characterized and analyzed.
The era of foragers began about 250,000 years ago. No written evidence of this era makes it difficult for historians to study. It was the first and longest era of human history. They searched and hunted for food and other necessities. Foragers only took from the land what was necessary to survive. They had no need for material possessions. Small numbers of humans were scattered over large ranges of land. Having small communities isolated them from epidemics but they had a low population growth rate.
“An Essay on the Principle of Population” is written by Thomas Malthus where he outlines his theory on population growth. He thought that if population continued to grow, food production wouldn’t be able to keep up with demand and he believed that many people would die due to famine. Either people would have to use more contraception to drop the birth rate, or the death rate would increase due to wars, disease or
Many scientist and specifically sociologists are concerned with the population on planet Earth. Many couples today are choosing not to have children. This choice does not just effect the couples personally, however it effects the whole country's demographic. The increase in childlessness among couples generates economic and social problems. Many countries are facing this problem. Hara in a journal article mentions that Japan and Germany are a couple of the countries that are going through childlessness (Hara, 2008).Today, more than 80 countries depend on immigration to prevent the populations from declining, due to the death rate being higher than birth rate. (Becker-Posner, 2013) How will declining birth rates affect demographics in many countries around the world? How will it affect the Global economy? How will it affect societies in different countries; will it raise social and racial tensions? Will it affect relations
As the year approached the seventh century, a warmer climate change allowed for higher elevation of lands to be used (Johnson 3, Mason). New techniques, tools, and more land contributed to more food production and a growing population. Agriculture was an extremely important aspect of medieval life that affected everyone from kings to even landless peasants. In fact, ninety percent of the population worked the land (Singman 75). Agriculture evolved over the centuries, and during the medieval ages, it was revolutionized.
Overpopulation Problems in China In spite of the great achievements that China has achieved in the recent years, our country is still a developing country, which is facing many serious social problems. The most serious of all is overpopulation, for it has a passive influence on the national economy, education and environment. First and foremost, overpopulation is the main obstacle to the economic development in China. The limited natural resources in China can hardly support the excessively large population.
Human population growth tends to occur in developing countries, where education is poor, particularly among the women who do not want to have fewer children, and the economy is poor. These developing countries are rich with history and the women have ideologies and pressures from the surrounding communities to bear many children. Religion is also heavily practised by the nations, and in some of these religions multiple children is desired. A male may also have the right to marry several women, all of whom he has multiple children with.
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.
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.
Since the beginning of mankind, we have reached many great achievements. We have developed many technologies and theories to solve and explain many of our questions and to improve human life. Through our years of evolution, we have severely increased our own survivability. This has been a great achievement for us, but in the recent decade, overpopulation is becoming a great issue. In the recent years, the rapid increase in population growth has troubled many in the field of political sciences. Scientists like Ehrlich have calculated and expected our population to grow even faster if we do not act upon the increasing rate of population growth. The birth rate of our planet is increasing exponentially, meaning that the birth rate has surpassed the death rate and that the rate of growth will only increase if left alone. The politics of population is a debate that involves both the fields of sciences and moral and ethical considerations. Science may provide an insight of
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...
Around 60,000 to 70,000 years ago the human population nearly became extinct. The population went from around 2 million people to only around 3,000 people. Scientists think this was thanks to the combination of a super-volcano erupting and the ice-age.
...he second way to attempt to decrease the population is through increased active family planning programs. Especially in poor countries, it is a lot harder for women just to jump into the work force, and even harder for a poor country to become industrialized. For example, in Bangladesh, one of the world's poorest countries, birth rates have decreased from seven children per family to only 5.5. This is largely because forty percent of Bangladesh's woman now take part in some form of family planning.
