Demographic Conditions Responsible for Population Aging

This article develops and applies two expressions for the rate of change of a population's mean age. In one, aging is shown to be negatively related to contemporary birth rates and death rates. In a general sense, aging occurs when vital rates are too low, as illustrated through applications to the United States, the Netherlands, and Japan. The other expression relates the rate of aging to a population's demographic history, in particular to changes in mortality, migration, and the annual number of births. Applications to the United States and Sweden show that the dominant factor in current aging in these countries is a history of declining mortality. Migration also contributes significantly but in opposite directions in the two countries. The two approaches are integrated after recognizing that the rate of change in the mean age is equal to the covariance between age and age-specific growth rates. A decomposition of this covariance shows that the two seemingly unrelated expressions contain exactly the same information about the age pattern of growth rates.     

人口转变完成后的中国人口老龄化

在人口转变完成之后。由于人口惯性的存在,人口老龄化将比人口转变过程中的人口老龄化速度更快。中国已经基本完成人口转变,进入了人口老龄化的加速时期,老年人口比重和规模以及老年人口乘数均快速上升。因此,必须在思想上对人口老龄化问题真正重视,实现人口政策和人口工作的重心从控制人口数量向数量与结构并重转变,并尽快完善我国的养老保障制度。     

Demographic Dividend,Population Aging and Raising the Retirement Age

China’s low fertility combined with increase in average life expectancy is leading to disappearing demographic dividend and population aging crisis. In this case, we may have a policy choice to raise the retirement age. Because the disappearing of demographic dividend gradually and the reversal of labor supply and demand may be the driving force of raising the retirement age, and the payment crisis of pension system which caused by the population aging may be the pulling force of raising the retirement age. If we consider the impact of this policy on urban employment and the laborheterogeneity in current conditions, we should carry out the practical policy which raise the retirement age slowly progressive and gradually.     

Understanding Global Demographic Convergence since 1950

Is the world converging to a single demographic regime? Or are groups of countries following distinct paths through the process of demographic transition? The answers to these questions are pivotal to our understanding of the nature and mechanisms of population change. They are also key elements for deriving the assumptions that should underlie population projections. There has been considerable interest in global demographic convergence during the last decade, with most work drawing on statistical methods that are widely used in economics. This article takes a different approach to most of the existing literature, examining the fertility and mortality trajectories over time that various appropriately defned world regions have followed. The data suggest that five distinct regional histories can be traced in mortality, and three in fertility, and that global convergence has moved more rapidly and unambiguously in fertility than in mortality.

Demographic Responses And Population Change

Most Western societies have gone through a process of population change during the past 100-150 years. One important aspect is the socalled demographic transition: the shift from high to low birth and death rates, and accelerated growth resulting from the lag between falling mortality and falling fertility, in national populations. Equally important has been the "rural-to-urban" transition, which involved the migration of millions of people from rural areas. It is hypothesized, following the suggestion of Davis (Theory of the Multi-Phasic Demographic Response), that the adjustment in reproductive behavior made by a community in response to a rising "strain," such as that resulting from higher natural increase, is likely to differ depending upon the ease with which the community can relieve the strain through out migration. Relationships among such characteristics of modernization as intensity of industrialization, speed of urbanization, structural changes in the agricultural system, and declining fertility are implied. Case studies of England and Sweden lend support to the hypothesis: more rapid urban-industrial development, larger-scale movement from rural areas, and a delayed decline in the rural birth rate distinguish the English transition.     

从人口转变到人口均衡

我国快速实现人口转变,使老龄化社会于世纪之交提前到来.在一定的资源环境和技术、制度条件下,统筹解决好人口总量较大与结构矛盾突出的"两难"问题,成为现阶段人口均衡发展的基本命题.如果及时实施全面两孩政策,并择机进一步调整人口及相关经济社会政策,将妇女生育水平提高到1.8左右并逐步回归到更替水平上下,那么,未来三、四十年,我国人口将趋向于一个稳定人口,年龄构成和城乡构成将大体稳定下来,60岁及以上老年人口比例约为1/3,老龄化程度达到发达国家的整体水平,但仍低于德国、日本等国家的水平,城镇化率达到75％左右;届时,人力资本积累居世界前列,基本实现国家现代化,人口自身各要素之间及其与经济社会资源环境之间可望保持总体协调.     

Population policy in Western Europe

Abstract Policies concerning procreation and fertility are considered first. In Western Europe there are countries which fully recognize and implement the personal rights of the individual to plan and space the number of children, as well as others denying these rights. The nature and implications of laws and policies concerning contraception, abortion and family planning in general are briefly described and their effects discussed. The second topic considered the welfare and the economy of the family. The incidence of family allowance schemes, taxation systems, protection of working mothers, educational facilities (especially for children of pre-school age), and publicly financed housing is reviewed in an effort to understand whether the various social and legislative systems favour procreation and the raising of the children. The situation is contradictory: very mild pro-natalist effects of family allowances are partly offset by a taxation system that im unfavourable to the family, since husbands' and wives' incomes are in many instances assessed jointly. Increasing protection of working women may reconcile economic activity with childbearing, but serious shortage of institutions to care for very young children makes employment of mothers difficult. The third topic is mobility, internal and international. Possibly the most serious demographic problems of Western Europe are the strong internal streams of migrants, congestion of cities and depopulation of rural areas. Measures for coping with these problems are generally in adequate. At the same time, international migration in very strong with many millions of foreign workers in various countries. The countries of immigration, although themselves tending towards almost stationary populations, seem not to accept the implications of this fact - particularly the cessation of growth of the domestic labour force. Temporary import of manpower through temporary immigration is a short-term solution which cannot be sustained indefinitely. The paper concludes with a final consideration. Western European countries could probably lower their levels of fertility rather easily by giving more support to family planning programmes, liberalizing abortion, etc. But should fertility consistently and for a long time fall below replacement, where are the measures for stimulating recovery?

Demographic Changes in Myanmar since 1983: An Examination of Official Data

According to official estimate, the total population of Myanmar reached 59.8 million in 2010. Yet, serious doubt exists on the reliability of these data. From the body of empirical evidence, best estimates of mortality and fertility are derived and serve to reconstruct prospectively the population of the country from 1983 to 2010. Despite the uncertainty regarding the levels and trends in international migration, the results are unequivocal: given the observed development in mortality and fertility, the population of Myanmar could not have reached 59.8 million in 2010. In addition to encouraging reconsideration of current population estimates, this analysis should also prompt the government and the international community to redouble their efforts in preparing for the 2014 census; carrying out a high‐quality count of the entire population, ideally followed by a post‐enumeration survey; conducting a thorough analysis of the census data; and publicly releasing the census results and accompanying analytical volumes in a timely manner.

Population policies in socialist countries of Europe

Abstract The emergence, in the mid-sixties, of policies aimed at counteracting rapid fertility decline in some socialist countries of Europe is discussed in the paper. Following a summary of recent population trends and policies in nine European socialist countries, and brief comments on ideological and theoretical considerations, factors relevant to policy decision are discussed. Population policies aiming at encouraging fertility exist in five countries, viz. German Demographic Republic, Romania, Bulgaria, Hungary and Czechoslovakia. Recent developments appear to include attempts to stimulate third births with measures aiming to improve economic conditions of large families, the status of women, education and restriction of induced abortion.     

Study on Standard of Population Aging

Do an increase in ageing in developed countries and"getting old before getting rich"in developing countries indicate that f luctuations in the population age structure have produced a qualitative change?What is a qualitative change and what is a quantitative change?Here we propose a new concept of Shadow Population,then establish a new standard for evaluating population age structure,finally present a typical five stage population age structure type transition model.The model simulation shows that all world regions are still in the adult stage and that population ageing belongs to the category of quantitative change.However,sustained low fertility will lead to a qualitative change in the ageing population.The current pressure of population aging in the adult stage placed on the pension security system shows that this system is truly not a sustainable system,Gradually raising the retirement age and Long-term stability in replacement fertility is the key to solving the socioeconomic development dilemma presented by future population ageing in low fertility regions or countries,but the latter is more urgent.
