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. 2.
Over population has become a huge problem in the world today. There has been a decline in the death rate and a rise in the birth rate. This is because of all the accomplishments the world has made technologically. Nowadays were able to stop a disease before it affects you. Which lowers the possible chance of some sort of illness challenging the population.
With increasing quality of healthcare, many countries around the world are now experiencing an ageing population. This involves a change in the demographic composition of the elderly and the young in a population. This means that there is a decrease in fertility rates with an increase in the number of elderly people (over 65). Therefore, the average age of the population is increasing. According to WHO, “this population ageing can be seen as a success story for public health policies, but it also challenges society to adapt, in order to maximize the health and functional capacity of older people as well as their social participation and security.” The UK is considered to have an ageing population (2013- 10 million over 65 in UK); some may perceive this to have negative consequences due to several factors: for instance, many argue that the ageing population places pressure on public health services.
Coronary artery disease is the number one killer of men and women in the U.S. (Jacobs, 1999). It develops from several risk factors. The purpose of this paper is to identify and explain the modifiable and non-modifiable risk factors of coronary artery disease, as well as other cardiovascular related diseases. This paper also addresses preventative steps individuals can take to lesson their chances of developing coronary artery disease and other related disease. Obesity worsens these risk factors, and is linked to the other risk factors, causing the risk of coronary artery disease to increase.
Report on Characteristics and Consequences of an Aging Population An ageing population is a population that, for a number of reasons, is collectively and gradually growing older. The main reasons for this are falling birth rates while death rates remain static. An ageing population can, however, have severe consequences for a country, which will be described below. In this report, the characteristics and consequences of an ageing population will be described using specific case studies on a world, and regional scale. Areas where population is ageing will be shown and reasons why the population is ageing in these areas will be outlined.
The challenges and impacts of ageing population on OECD countries: higher age care facilities requirement and healthy life expectancies The challenges and impacts of ageing population on OECD countries which are; higher requirement of aged care facilities and the prevalence of health expectancies are examined in this essay. Several factors like nutrition and effective nursing care are the significant reasons behind this. The population of the world will age much faster in the next decades than previously with the continuation of fertility decline and increase in life expectancy (Auer & Fortuny, 2000). Ageing is the fact of human life we are born; we grow up and become older and in due coverage time we die. As this course of human life is celebrated as a human success but rapid and wide spread ageing is one of the key elements transforming the influence in quality health development and productivity.
title of website or page? YOUR HEALTH IS YOUR WEALTH Research has shown that there is a direct correlation with unequal societies and poor heatlh. The findings suggest that determining health in a society, is dependent on how wealth is distributed. Past data has indicated that there is better life expectancy where their is more equal distribution of income. The most unequal places have the highest death rates, with a small decline Policies that address equal income distribution have a large impact on health of the population.
There are four phases of demographic transition which are based on if the population is stable, growing, or declining in each. Stage one of demographic transition there is a higher level fluctuation. Which correlate the balance of high death rates and high birth rates within the Pre-modern times the high rates are believed to be high due to the extremely slow population developments. However during the stage one of demographic transition with high fertility and mortality rates as well as slow population growth is conducive to a stable population (Montgomery K. (n.d). Stage two of demographic transition, urbanizing industrializing early expansions there is high birth rates and falling death rate when this occurs there will be a rise in the population growth due to the lower death rates.
Population growth of developing countries, half of which are poor low-income countries, will continue to grow, while populations of developed countries will stabilize or even decline (Wright 2005). Epidemiological transition is a pattern of change in morality factors. We can consider it as the shift from infectious and deficiency diseases to chronic noncommunicable diseases (Wahdan 1996). The epidemiological transition was thought to be a unidirectional process, beginning when infectious diseases were predominant and ending when noncommunicable diseases dominated the causes of death. It is now evident that this transition is more complex and dynamic where health and disease evolve in diverse ways.
Basically, this demographic shift springs from advances in medical technology, education and economic growth. The Economist (2009, p.2) notes that another passing cause is the baby-boomers who are going grey after the second world war The population structure change produce a series effects on employment, government finance and consumption level. As I see it, there are three potential crises in global economy which caused by graying. Labour shortage I focus on work force in graying countries. I put forward three reasons on this point.
