人口的年龄结构是人口再生产类型的重要标志,而年龄中位数、老年系数、少儿系数、老少比是反映一个社会人口年龄结构特征的几个主要指标。但这些指标的地区差异参差不一,往往很难籍此将各地的人口年龄结构状况列出一个序次。本文试用模糊数学中的优先比定序法,分析全国各地人口年龄结构与上海的对比,列出其相似亲疏序次。  相似文献

人口年龄结构是经过多年人口自然增长和迁移变动等综合作用而形成的客观状况,对未来人口发展的速度和趋势以及国家或地区经济社会整体发展产生重要影响。本文通过对1995~2014年数据的实证分析,发现20年来我国人口年龄结构呈现以下特征:少儿人口数量减少且比重呈持续下降趋势;劳动年龄人口数量稳步增长且比重呈稳定上升趋势;老年人口数量持续增长且比重呈上升趋势,老龄化进程加快。总体人口年龄结构呈现老年型,各地区人口老龄化程度存在差异。各地人口负担系数存在较大差异,人均GDP与总抚养比和少年儿童抚养比呈负相关,与老年人口抚养比呈正相关。经济发达省市区人口负担系数较小;城乡人口比例呈持续升高态势;城乡人口总抚养比和少儿抚养比呈下降趋势,城乡老年人口抚养比呈稳步升高态势;乡村人口抚养比高于城镇。  相似文献

山东省人口老龄化空间分异及其形成机制研究   总被引:6,自引:0,他引:6  
研究人口老龄化的区域差异及解释其成因,对合理制定人口发展战略具有重要意义。本文从时空角度探讨山东省人口老龄化进程,构造模型分析老龄化空间分异变动的制约因素,采用两种分布比较方法定量研究各制约因素的影响程度,最终揭示老龄化程度区域差异扩大的动力机制。结果表明,山东省老年人口比重出现极化现象的主要原因在于人口自身的惯性作用,包括人口年龄结构和出生率的共同作用,此外还受到经济社会诸多因素的制约。  相似文献

浙江省的人口年龄结构已成为典型的老年型人口 ,人口老龄化程度在全国处于领先水平。未来老年人正向中、高龄发展 ,老龄化速度快。老龄化程度在城乡及地区间分布不平衡 ,老龄化超前于社会经济发展水平 ,生育率下降是导致人口老龄化的主要因素。在 1970— 1990年实行计划生育的 2 0年里 ,生育率的迅速下降是人口年龄构成变化的主导因素。对未来人口年龄结构影响最大的是年龄构成的作用并使人口年龄结构老化。生育率降得越低越好是一个观念误区 ,而应把优化人口结构和控制人口总量放在同等重要位置  相似文献

This article provides an overview of changes in the U.S. child population (persons under age 18) based on data released from the 2010 census. Today, the number of children in the United States (74.2 million) is at an all-time high, but the share of the national population who are children (24 %) is at an all-time low. The number of children in the population grew by 1.9 million between 2000 and 2010, but the overall national figure masks many important details and divergent paths. The growing racial and ethnic diversity in the U.S. is more advanced among children than among adults. Some areas of the country and some demographic groups grew significantly over the decade, while the number of children in other areas and in other groups fell.  相似文献

The rate of urbanization is far more rapid in sub-Saharan Africa than in any other major region of the world. However, little is known about patterns of ethnic residential segregation in rapidly urbanizing African cities. This paper is crafted to make an important contribution through its focus on Ghana’s two largest cities: Accra and Kumasi. Making use of the most recent population and housing census data of 2000 to generate a Location Quotient index, the analyses explore the cities’ degree of ethnic diversity and concentration for comparative purposes. In relative terms, the study reveals that the level of residential ethnic segregation is fairly balanced in Accra compared to Kumasi. However, there are important differences between the findings of this Ghanaian case study and findings from research in the West, where the residential segregation is heavily determined by cultural/racial factors in addition to socio-economic factors. In the absence of institutional and ethnic discrimination, the most fundamental underlying cause of segregation in the Ghanaian case appears to be the socio-economic circumstance of ethnic groups present in the cities. The paper concludes by exploring the implications of the study for urban and national development in Ghana as well as the future patterns of ethnic clustering likely to emerge in Accra and Kumasi.  相似文献

The substantial growth and geographic dispersion of Hispanics is among the most important demographic trends in recent U.S. demographic history. Our county-level study examines how widespread Hispanic natural increase and net migration has combined with the demographic change among non-Hispanics to produce an increasingly diverse population. This paper uses U.S. Census Bureau data and special tabulations of race/ethnic specific births and deaths from NCHS to highlight the demographic role of Hispanics as an engine of new county population growth and ethnoracial diversity across the U.S. landscape. It highlights key demographic processes—natural increase and net migration—that accounted for 1990–2010 changes in the absolute and relative sizes of the Hispanic and non-Hispanic populations. Hispanics accounted for the majority of all U.S. population growth between 2000 and 2010. Yet, Hispanics represented only 16 % of the U.S. population in 2010. Most previous research has focused on Hispanic immigration; here, we examine how natural increase and net migration among both the Hispanic and non-Hispanic population contribute to the nation’s growing diversity. Indeed, the demographic impact of rapid Hispanic growth has been reinforced by minimal white population growth due to low fertility, fewer women of reproductive age and growing mortality among the aging white population America’s burgeoning Hispanic population has left a large demographic footprint that is magnified by low and declining fertility and increasing mortality among America’s aging non-Hispanic population.  相似文献

Changes in population characteristics are associated with changes in the prevalence of physical and related health conditions with alternative types of population change leading to change in the prevalence of certain conditions. Examination of the effects of future demographic change on such conditions is, in turn, critical for understanding the future need for various types of health-related facilities and services. This article provides an example of how future demographic changes are likely to impact overweight and obese status in Texas, a rapidly growing and diversifying state. Specifically it uses population decomposition techniques to examine the relative impacts of population growth, aging and changes in the racial/ethnic composition of the population on increases in the prevalence and related costs of overweight and obesity in Texas, an important input for the formulation of statewide health policies. The number of overweight adults in Texas is projected to increase from 5.5 million in 2000 to 16.0 million in 2040, and the number of obese adults to increase from 3.5 million in 2000 to 14.6 million in 2040. The largest projected increases occur among Hispanics and other minority populations and for all race/ethnicity groups the increases are largest among those who are 65 years of age and older. Decomposition analysis indicates that of the projected increase of 10.5 million overweight adults from 2000 to 2040, 54.0% is attributable to population increase, 15.0% to change in age distribution, and 31.0% to change in racial/ethnic composition. Of the projected increase in the number of obese adults, 61.6% is due to population change and 38.4% to change in racial/ethnic composition. The annual costs associated with overweight and obesity prevalence are expected to increase from $10.5 billion in 2000 to $10.5 billion in 2000 to 40.3 billion in 2040. The results suggest that services to address these conditions will need to be widely dispersed across the state with particular concentrations of the elderly, Hispanics, and Other minority populations.  相似文献

Recent literature has suggested that population aging may shape energy demand and related emissions. Recent scholarship also suggests that emissions play a role in contemporary climate change and, as such, understanding the effect of population compositional change has considerable environmental policy importance. The purpose of this paper is to empirically investigate the macro-level relationship between population aging and emissions of sulfur dioxide. We extend a standard macroeconomic estimation function by including the age composition of the population. In doing so, we separate, for the first time in the literature on aging and the environment, the life-cycle dimension of the age structure from its cohort dimension. We utilize data representing a balanced panel of 25 OECD countries during the period from 1970 to 2000. Consistent with our expectations, we find that societies with a low proportion of young and a high proportion of senior citizens emit more sulfur dioxide. At the same time, our results suggest that a high proportion of individuals born before 1960 is positively correlated to national sulfur dioxide emissions. Our study contributes to understanding of past emission patterns in OECD countries and the findings may allow for improvements in future emission projections.  相似文献
