Analysis and Comparison of Aging Population in Europe and Asia During 1950 to 2015

Abstract

1Objectives The study aimed at performing a comparative analysis of the aging population in European and Asian countries during 1950 and 2015.Methods & Materials This study has been conducted through a secondary analysis, and the data for 90 European and Asian countries were derived from the UN Population division. The used statistical method was history of survival analysis. The statistical package of Stata was used to perform statistical analyses of non-parametric methods of estimation of Kaplan-Meier and Nelson -Ellen's survival function, and Cox's semi-parametric proportional hazard model. Results The study estimates showed that total fertility rates and life expectancy in both Europe and Asia were convergent in nature. The probability of occurrence of aging has a negative relationship with total fertility rate and a positive relationship with life expectancy. Estimation of survival function and cumulative hazard function for the two study areas in 2015 indicated that probability of occurrence of aging was significantly different. Survival function of aging was close to zero for European countries. This means that most European countries have entered the aging process while the likely to survive an accident for Asian countries was more than 0.75. Conclusion According to the results, during 1950 to 2015, the percentages of aging populations in all regions of the European continent was dramatically higher than that of the Asian countries. In recent decades, although there has been a rapid fall in fertility rate and increased life expectancy among the less developed Asian countries, the process of population aging has increased. This index in Asian countries is believed to outpace the European countries by 2050. A B S T R A C T Objectivesurrently, due to changes introduced in the age structure of the population in many countries, it seems necessary to investigate the population aging phenomenon in order for planners to pay more attention to the trend as well as the positive and C negative consequences of aging. Therefore, the aim of this study was to review and compare the process of population aging in European and Asian countries during 1950 to 2015. This study is significant as it involves the comparison of the aging process in Europe and Asia while recognizing the change in age structure among the countries of these continents. This study also evaluates the time of arrival and the time spent at different stages of demographic transition from youth to old age. Also, considering that demographic tran-31 Spring 2017. Vol 12.

Inclusive Design: An Approach to Adapt Homes for the Elderly

“…The aging trend of the world population [6,25,[50][51][52] has increased the number of elderly people [2,3] due to the decline in fertility rate [53,54] and increase in life expectancy, as mentioned earlier [54,55] . In turn, this issue has exacerbated the living problems of the elderly [54,56].…”

“…In recent years, this trend has also been observed in other countries. Population aging is mainly caused by the reduction in fertility and increase in life expectancy around the world [2,3] . In less developed areas, fertility decline has started later but proceeded faster.…”

“…By 2050, life expectancy is predicted to reach 83 and 75 years in more and less developed areas. As a result, the rate of aging is assumed to increase in all parts of the world [2][3][4][5] , so that the world's elderly population (65 years and older) is expected to triple by 2050 [6] . The elderly population has the fastest growth rate in the total population throughout the world.…”

“…In the United States, this age group is supposed to double and reach 71 million by 2030 [8] . Statistics also show that the number of people aged 60 years and over has doubled in the last three decades so that the number of the elderly has been predicted to rise from 795 million in 2010 to 2 billion in 2050 [2,4] . Moreover, by 2020, according to the World Health Organization (WHO), 20% of the world's population had been made up of people over the age of 60 years [9,10] .…”

“…(2) With regard to the growth of the elderly subjects, attention to aging and its issues, including health and welfare issues, is a necessary subject. (3) Elderly problems are associated with an increased risk of illness and complications. Dementia (including neuro-cognitive impairment) one of the most common neurological disorders and one of the most important health threats in the elderly.…”
