Introduction:
Demography is the study of human populations (Thomson, 2007). Demographers study characteristics such as birth, death rate, sex, ratio, and age structure in a population. Studying such changes is useful in the understanding of social, and economic problems which help to identify possible solutions (Thomson, 2007). The study of Demography allows us to be able to comprehend and analyze economic and social trends which is crucial in preparing for future developments. (Legislative Assembly of New Brunswick, N/A).
Past studies have shown that demography data allows understating of the cause of death in the past, therefore allowing a possibility in postponing the death age in the future (Fries, 1980.) For example, non-traumatic and

The cause could be due to less advanced medicine in the pre 1850s, than in the post 1950s (Randolph, 2009). In the journal The Evolution of the U.S Healthcare System, it states that it wasn’t until the early 1800s that physicians began to think that germs might cause and spread diseases. This indicates that their medical understanding was still fairly low. Between 1885 and 1922, there was a growth not only in medical technology but also in academic medicine (Devine, 2017). Therefore, the previous statements explains why both post 1950 males and females had a higher chance of survivorship (figure 1), lower mortality (figure 2) and higher life expectancy (figure 3). Pre 1850 females had the lowest life expectancy especially between the ages of 20 and 40. Between those ages are when women generally have babies due to the “fertility window” (Bellieni, 2016). In the 1850s, most births took place at home which lead to prolonged births with excessive bleeding and infection which often lead to death (Middendorf, 2017). Based on Figure 1 and 2, post 1950 females had the highest chance of survivorship and the highest individual life expectancy. By the early twentieth century, more hospitals were built, doctors had more authority, and there were advancements in medical sciences related to diseases, improving the quality of childbirth (Randolph, 2009). In 1965, the Supreme Court of the United States gave women the right to private use of contraceptives (Chesler, 1992) decreasing death during childbirth. Overall, pre 1850 maless and females had the lowest chances of survivorship and lowest life expectancy which then changed in the post 1950s due to medical advances causing their chances of survivorship and life expectancy to rise and mortality rate to
During the Industrial Revolution of the Victorian Era, life expectancy was so low due to the lack of sanitation, working conditions, and less medical knowledge that we have now. At the time, the average age people were dying was at 35 years old (Lambert). The age, however, varied depending on where one lived. Normally, people who lived in cities died at a younger age than people who live in rural areas. The class that one was in also greatly impacted a person’s life span. It mainly impacted poor working-class communities, because of the poor conditions that came with being a member of that class (Wilde).
The contributions of several doctors, researchers, and scientists helped improve the health of the growing population. In 1850 the average life expectancy was 42 years. By 1910 the average life expectancy had risen to nearly 55 years. Between 1850 and 1910 there were several advances in the medical field. The introduction of genes, white blood cells, blood groups, insulin, rubber gloves, aspirin, and vitamins and the discoveries of Pasteur, Charcot, Halsted, Zirm, Lister, and Koch were the starting point of an international fight against disease.
In the Early 1900s, health care was very limited to rural women. Adequate care and practice for childbirth was never heard of and often times performed by family members or even neighbors. It was said to be lucky if a child lived through the birth and even luckier if the child lived through their first birthday.

A geographer would be able to show the world the positives and negatives that could come from stable population and crazy rising population growth. These documents make the world spin on their heads because they really pull you towards each direction. Document d gives us the idea of what the numbers could be if population continues to grow at the rate it is today. It also gives us sources that expect the population to stable out in future years and not go to unbearable numbers. Document a shows how the world starts with plenty of food/supplies, but then after a while doesn’t have much left for the world’s population. Document c shows how much people are living off of $2 a day and how much struggle they would have if the supply and demand starts rising causing things to be higher prices. I believe that these three documents will cause the world to have so much worry and have no clue of what truly is going to happen in future years. In my opinion, a geographer only really has what ifs and guesses to show the patterns that emerge and could emerge in the upcoming years. All in all, there are tons of causes of population growth and tons of negatives that harm population
As an object of analysis sociologists defines population as an aggregate of people in a geographical area that has size and longevity. The size has a lower limit of two and no upper maximum. Longevity varies and has a lower limit of zero with no known upper limit. Populations are by definition made up of individuals. The study of human population is termed demography. Demography studies the size and composition of a population, as well as migration and location of the population. Demographers track birth rates and death rates and monitor the population growth and try to explain them in terms of the social system's development. A good example is the Malthusian theory in which population increases geometrically and the resources increase arithmetically resulting in a lack of resources resulting in famine and war. Fortunately the theory is flawed in that it does not consider social factors such as artificial contraception and the burden of large families in a post industrial society. The way a population interacts with the environment creates a social system. The social system draws on the population and affects the population. An example of this is in India where the ratio of men to women is 108 (108 males to every 100 female) while the sex ratio of most other nations is below 100. The cause for this disparity ...
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).
...ed four projections of Sydney’s population to represent the impact on Sydney’s size and age structure of the four projections for the years 1999, 2009, 2019, 2039 and 2049. In the diagrams, each successive layer from the bottom to the top represents the size of the population in a five year age group. The male population is portrayed on the left side of the diagram and the female population on the right. It was found under all the years 1999, 2009, 2019, 2039 and 2049; the population becomes distinctly older, with the proportion of the population aged sixty-five and over increasing from twelve percent in 1999 to twenty-four percent in 2049 (McDonald and Keppen 2002). It can also be determined that the population pyramids show that the slightly younger population results prove higher fertility and higher migration in Sydney for the future (McDonald and Keppen 2002).
“Some of my colleagues at the Department of Sociology in Helsinki wonder whether it is meaningful to study mortality differences. After all, the death rate is the same for everyone: one death per person” (Valkonem 1993)[1]
In today’s society, what was once said to be true and taken as fact regarding older people is no longer the whole story. As Laslett states, “At all times before the middle of the twentieth century and all over the globe the greater part of human life potential has been wasted, by people dying before their allotted time was up.” (1989a), and to a great extent a lot
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 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.
Firstly, the living rates for women getting out of the process of childbirth between 1800 and 1900 had been gradually going lower, especially due to advances in medicine, thus proving a higher advantage for women later on. Though it’s naturally expected for many deaths
Nepal is a landlocked country, sharing border with largest and fastest growing Economy in the world; China and India. It is has a total surface area of 147,181 square kilometers (56,827 sq miles). Nepal is home of 8 most highest mountain in the world. Topographically, Nepal can be divided into four ecological category; Lowland (Tarai), Midland, Highland and Trans Himalayan. Tarai occupies low and flat land also known as food basket of Nepal.
