Population growth is one of the ways a sociologist can view the changes within society. A population consists of everything or everyone being studied in an inference procedure. Populations can be large in size, although this is not necessary. What is important is that a population includes all of what we are curious about. Populations consists of groups, which must be living in the same area at the same time (Taylor). The number of individuals that inhabit a place in society at one time is called size. The number of individuals in a specific area refers to the density. And lastly, the size of the population as it changes overtime is the growth population.
We know a population consists of groups of individuals in a particular area. The amount of people in area is determined by three main things. The amounts of live births, deaths, and natural changes: such as migration. The birth rate refers to the number of children which are born. The CIA Site Redirect states: the average annual number of births during a year per 1,000 persons in the population at midyear; also known as crude birth rate. The birth rate is usually the dominant factor in determining the rate of population growth. It depends on both the level of fertility and the age structure of the population (CIA Site Redirect, 2010).
As one would deduce, the number of deaths within a population can affects its growth. Death rate, which does not account for all categories of mortality in a population, it is a point at which to gauge the mortality situation in a country, accurately indicates the current mortality impact on population growth. The average annual number of deaths during a year per 1,000 population at midyear; also known as crude death rate (CIA, 2013).

For example, Document “C” is a letter from a farm family to Richard and Ruth Bennet, May 1843. The letter explains that the family could no longer support the farm land. The family the decides to split up and move to Mill town. The children are having bad luck getting in and working. Some family members stayed behind to take some care of the farm property. In summary, the population increased in domestic migrates which then means their is more land. When there is more labor, more manufacturing and more consumers. Document G shows a large increase in population between 1820-1860. The graph shows the slope ( increased and decreased) of immigrants. Population increased in the United States from the result if many “push and pull” factors. For example, a push factor would be a reason to leave that location; hence religious reasons, scarce food source,government problems etc. For many immigrants,America was a land full of opportunity, pull factors made immigrants want to come to The United States. The land was very cheap, making settling a new area cost little to nothing. Our rights were very different than Germany and Ireland (where most immigrants came from during this time period). Freedom of speech, jobs and opportunity were some major factors in the U.S. Many other countries did not have the ideas and technology we have Making technology, government and transportation be a factor for a big
There are three main factors that fuel rapid population growth in the world. Firstly, the increased production and distribution of food has now enabled more people to live longer lives. Initially, starvation caused high death rates, therefore inhibiting population growth. In our modern society, there is an abundance of food to feed the population. Improved distribution channels have enabled food to reach into dry places, thereby eliminating the risk of starvation. Secondly, there is an overall improvement of public health care. Poor sanitation and lack of clean water were the main causes of deadly diseases like malaria. These diseases often wiped
“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
...5 million people. By the end of the nineteenth century, it had reached around 390 million people. The rapid population growth reflected changing patterns of fertility and mortality. Once the medical advancements took place, physicians were able to help prevent diseases and the mortality rates started to lower. The fertility rate started to increase because more infants were able to grow into adults, which was resulting in rapid industrializing societies.

Until recently, the term “population growth” has always been regarded in a positive manner; still many people believe that a growing human population results in a growing economy. While many people debate whether a reduction in our total numbers is necessary, others debate what the effects would be. Not only does our population affect the economy, but also our environment, education, quality of life, and everything around us depends on how we react to this growing problem. Our population is growing and we must decide how we will react and what effects our actions will have.
Population - set of people who are living or residing in certain countries, parts of the world, in the world as a whole. The concept of population is not adequately understood as population, which is sometimes used to refer to a group of people, citizens, residents (eg., The population of the region, city, and so on.); often the term "population" is used as a synonym of population. Population issues involve demography - the science that is based on the analysis of economic, social, and biological and geographical factors studying patterns of processes in the structure, location and population dynamics. In my opinion, the population policies are important to U.S. and the United States' government should pursue population policies to protect our quality of life for future generations, as it helps to understand why population decreases or increases and let to understand how to cope with these issues.
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...
Growth is important in a society. If all the people meeting specific needs get too old to work or dies, there would be no one to take over that particular function. However, extreme growth could be a major problem and would be considered a latent dysfunction. The same could be said for environmental effects – some are to be expected and cannot be avoided, but too much would cause problems in the functioning of the population. Social conflict theory would view the problem with population growth as lying in the distribution of goods and unequal consumption. If everyone were using energy, water, food, and the like with the same careful consumption, there would be no problem with a larger population. However, some people, particularly those living in poverty, consume less and will still face the environmental issues that can arise, while the rich and powerful use too much and cause more problems. If the people that use more would act more socially responsible, there would be enough to sustain a population growth. Symbolic interaction theory would focus on the perception of the people in society and their views on things that affect the population growth and environmental changes. One example would be the contribution of having a large family to population growth, which could be prevented by birth control. However,
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 `Theory of Demographic Transition' 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 three main stages, which apply to third world, second world and first world nations. These stages or classifications demonstrate a transition from high birth and death rates to low birth and 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. The theory discusses observations made concerning social problems and their relation to each stage of transition; then attributes them to population. Through this model we can understand the relationship, characteristics, and transition between underdeveloped and developed nations as it relates to population.
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...
Population growth may be defined as the increase in the number of individuals in a population. In general a population will tend to increase in number when the available resources are greater than that required by the members of the population present at that particular time. As long as resources are available, every population has the tendency to grow exponentially.
