Overview
When considering the growth of the world’s population there Is a concentrated look at Four Main factors with a fifth element now ,slowly becoming a large factor.They are fertility rates, mortality rates (life expectancy), the initial age profile of the population (whether it is comparatively old or relatively young to begin with), migration, and now religion, where focus is placed on migrating to or from a particular faction.
The forces behind population change
Population Change:A view at Growth
Fertility has been on a slow descent over the last decade and is expected to continue declining.As a result,the world,s population rate is also slowing down. But from the year 2010-2050 ,the world’s population is expected to rise some 35%.That is approximately 2 Billion people.Fertility patterns may differ between countries, and larger geographic locations for a myriad of reasons, including cultural standards,degrees of economic improvement, education systems and government policies that encourage ,or discourage, family planning. Female reproductive rates may also be a result of infant fatality rates, participation in the labor market, income levels and social status, among other factors.("Main Factors Driving Population Growth | Pew Research Center," 2015)
Life Expectancy,which is the expected life term we are given from infancy,has been on the up-rise, and is expected to continue its ascent over the next four decades.Research has shown that people are living longer, due
Over the past years, there has been an exceptionally large national increase which has caused several population issues. These issues include: homelessness, deforestation and more fields being used to make space for shops and houses disrupting the biodiversity growth. Problems like this are caused when there is an abnormal increase in the birth rate where more babies are born; this is also known as a ‘baby boom’. This can occur when nations have more children as a whole and events like this normally takes place after an achievement – an example being when we won the World War Two. The country was relieved that the fighting was over so their instantly celebrated which is why more children were born. In the last 50 years alone, the population has doubled showing just how fast the population is actually growing and even though it may seem fortunate that there are less recorded deaths, this makes the Economical
Population growth has been running rampant in developing countries for the past century due to a lack of education, medical care, and gender equality. According to Jonathon Porrit, a British environmentalist and writer, “The combined population of the four countries [Ethiopia, Uganda, Somalia and Kenya] was 40 million in 1960. Now it is nearly 170 million [in late 2011].” “Overall, the human population has quadrupled in the twentieth century”(Cromwell 167) alone due to technological and medical advancements of the industrial revolution Because of the Industrial revolution, there have been many advancements in medicine, leading to lower morality rates in developed and developing countries alike. Developing countries lack the education and family planning that they need in order to maintain a stable and healthy population. Family planning is the act of” anticipate and attain their desired number of children and the spacing and timing of their births. It is achieved through use of contraceptive methods and the
The indefinite growth of the human population, has monumental impacts on the natural environment, not only in the UK, but around the globe. Architecturally, the entire process of designing and constructing a building, both domestic and not, can lead to the rapid exhaustion of natural resources across the planet. Building with environmental design strategies in mind not only combats the impact we as humans have on the natural environment, but also has considerable economic benefits, due to lower running costs of buildings and advanced occupant productivity. There are also many social benefits, such as improved air quality which resultantly leads too enhanced health of a buildings occupants.
Human population growth is becoming a huge issue in our world today. The population is increasing rapidly. The reason that it is becoming a concern is because it has affected the economic, environmental, and social aspects of our world. In the film Frontline: Heat, we can see how there might not be a future for our planet unless we are able to reduce the emissions and make our world a safe place. Not only for the present but also for future generations so that they are able to live long and healthy lives.
Life expectancy is the average number of years an individual is expected to live in a certain area/state/region. The Medical Daily reports that life expectancy is continuing to increase throughout the world, a sure sign of good news. However, it also reports that diabetes and depression are slowly on the global rise.
Major progress has been made in curbing population growth. The United Nations Population facts August 2010 states that there has been substantial declines in fertility, total fertility in the rest of the developing world(excluding the least developed countries) declined by about 50 per cent between 1970-1975 and 2005-2010: from 5.0 to 2.5 children per woman. Additionally fertility in the least developed countries dropped by 34 per cent since 1970-1975, from 6.7 to 4.4 children per woman. Bangladesh is exceptional with a reduction of over 60 per cent, from 6.9 children per woman in 1970-1975 to an estimated 2.4 in 2005-2010.
According to the United States census, the world population is over 7 billion and a birth occurs every 8 seconds. China leads with well over 1.3 billion people. There are rural areas, in Africa that women have never heard of any form of birth control. In those areas, women have 6 or more children. According to the United nations report (2013), The world 's population is expected to reach 9.6 billion by 2050. There is already a lack of natural global resources. The environment is showing signs of misuse caused by humans. While, reproduction is a part of life and a human right. We as people need to work on preserving our natural resources, for the betterment of our future. And, birth control is a considered method in helping control our population. Birth control is also another way of helping developing countries due to lack of obstetric care, or countries that are disease, and poverty stricken.
Life expectancy in the human race has risen dramatically in the past century (Harris, 2009) reaching its highest level for both males and females on record (Office for National Statistics (ONS), 2006). Japan currently has the longest surviving individual with a life span averaging 84 years for both men and women (World Health Organization (WHO), 2006). According to Rooney et al (2004) the term life expectancy is defined as ''the number of years that somebody can expect to live, according to statistics (p. 1084).Over the last 100 years, the expectancy of life has increased and the overall goal is to live a long and healthy life. Some social scientists have predicted that the western population has a possible life span within the range of 85-100years. Others have suggested that with medical advances humans can be expected to live beyond these ages. The longest-lived human on record was 122 years
All over the world, the human population fluctuates throughout each country due to several different factors. Some of the factors that can lead to an increase or decrease in population include industrialization, economic instability, poverty, laws, disease, resource destruction, sanitation, natural disasters, birth control, and access to education (Class notes). Although population decline is possible and relevant in some countries, the more important issue facing many countries today is overpopulation. Some over population problems include decreases in food sources, housing needs, land, increase in distribution problems, decrease in job availability, and poor health care environment (HowMany.org, 2014). One important question related to controlling
The life expectancy of humans has been increasing at a steady rate for a bit over a century. The increase is about one quarter of a year life expectancy per year. The graph is not showing signs of plateauing. Claims that the next generation my be the first to see a decrease in life expectancy, is scare mongering on the part of public health officials.
This spread in the demographic data available to contemporary researchers show that as nations become more developed, fertility rates do not increase exponentially as predicted, nor even linearly, but eventually plateau or potentially even decrease. This concept, demographic transition, has many contributing factors, many of which are uncertain. Still, even if these influences are poorly constrained, the overall trend towards replacement rates of reproduction is well established. The best example of steady and sustainable population levels is the European Union. The EU is highly industrially and agriculturally developed, yet has growth rates near zero percent, and not only a sufficient domestic food supply, but an exportable surplus of grains.
In 1930, Thompson developed one of the first theories to explain the decline in fertility rates starting to be seen in industrializing nations (Thompson, 1930). Joined by Notestein in 1953, this classical theory of demographic transition postulates that changes in social life from industrialization and urbanization would cause first a decline in mortality followed by a decline in fertility (Notestein, 1953; Mason, 1997). Since the early 20th century, the world has undergone major demographic changes. In the first decade of the 21st century for the first time, the old outnumbered the young, and the median number of children per woman fell below replacement levels (Cohen, 2005). These major changes illustrate the now well-known concept of
Life expectancy is the average length of time persons, defined by age, sex, ethnic group, and socioeconomic status in a given society, are expected to live. The older population is the most rapidly increasing segment of the U.S. population. Since 1900 the number of older adults has increased over ten times and their percentage of the population has more than tripled. This increase is projected to continue at a rate of 1.3 percent annually until 2010. (Torrez, p.132)
Long- term health care is a service that assists individuals, usually the elderly, with their day-to day living, that includes medical and non-medical care (Silas, 2012).
Beyond a doubt we urgently need to address the devastating global issue of population growth in the United States America before we destroy our planet. We are facing many devastating economic problems, such as pollution, global warming, education, but the most critical is overconsumption. Overpopulation is a huge problem in the United States of America, which is causing us to run out of natural resources. The human race is already too large and is destroying the natural systems that support us. There are many solutions to this problem, but the common factor is controlling the human race. What can we do as a society to help contribute to controlling the population growth? “The United States is the most overpopulated country in the world”. (Ehrlich)
