Residential preferences and population distribution

Public opinion research has revealed decided preferences for living in rural areas and small towns, and proponents of population deconcentration have interpreted this as support for their policies. This study, based on a national sample, yielded similar results, but when we introduced the additional possibility of a preference for proximity to a larger city, then the rural areas preferred were found, for most respondents, to be those within the commuting range of a metropolitan central city. Although persons wishing to live near large cities were found to be looking for the same qualities of living sought by those who prefer a more remote location, these findings are not, in general, consistent with the argument that public preferences support strategies of population dispersal into nonmetropolitan areas. Instead they indicate that most of those who wish to live in a different location favor the peripheral metropolitan ring areas that have, in fact, been growing rapidly by in-migration.     

非洲的人口动态与分布

非洲的人口动态长期以来具有高出生率、高死亡率的特点,20世纪90年代以后,非洲的人口动态由高出生高死亡模式向高出生中死亡模式转变．死亡率的持续下降在很大程度上是由于数种过去危害最严重的急性传染病基本上得到有效控制的结果。正是死亡率的下降和持续的高出生率导致非洲人口迅速增长。在非洲人口增长的过程中．人口分布是极不平衡的。非洲人口分布的变化与经济因素的人口定期迁移是密切相关的,大致可分为三种情况．这种独特的迁移模式均与经济活动和生产方式直接相关。     

Seven measures for population control announced in Guangzhou

On 7 October 1988, the Municipal Government of Guangzhou, China, announced the following Decision: "First, great efforts should be made to strengthen education on the situation and tasks of the family planning programme. Second, family planning work is included in the target responsibility system of leaders at all levels during their terms of office and whether it is good or bad for the fulfillment of their family planning tasks will be considered as one of the criteria for the assessment of cadres in their work to link up with rewards and punishments. Third, the current family planning policies must be resolutely and unswervingly carried out. For those units where family planning policies have not been well carried out and where family planning work has long been stagnant, competent authorities should send capable cadres to help them improve their work within a definite period of time. Fourth, the principle of 'three priorities' (i.e., priority of publicity and education to economic restriction, priority of contraceptive measures to induced abortions, and priority of day-to-day work to shock work) must be adhered to while technical service and work of transforming the backward situation in some places should be done. Fifth, the family planning organizations at all levels must be perfected and ranks of family planning workers be strengthened with the stress on those at the township, town, and street neighbourhood levels. Moreover, the family planning offices should be set up or full-time family planning workers be staffed for enterprises and undertakings in the cities. Sixth, funds for the family planning work must be guaranteed. Seventh, the management of family planning for [the] floating population must be strengthened and a management group for [the] floating population, which consists of representatives from the Municipal Government and departments concerned, must be established."     

Symposium on population distribution

The Development and Population Redistribution in South Asia symposium, held in Pakistan during January 1980, was organized around 4 major themes: 1) national, regional and local policies of population redistribution; 2) population redistribution aspects of national development plans; 3) development projects and population redistribution; and 4) settlement of refugees. A principal concern was the ecological impact of programs of resettlement, particularly in the tarai zone of India and Nepal and in the dry zone of Sri Lanka. A 2nd major concern fo the symposium was the spatial pattern of urbanization in each country. The final symposium under the term of office of the present International Geographical Union Population Commission will deal with migration and population redistribution in the Asia and Pacific region.     

Rethinking population distribution policies

Developed and developing nations are generally dissatisfied with the spatial distributions of their populations. Dissatisfaction is particularly acute on the part of developing nations which view their problems of population distribution as more serious than those of natural increase. The overwhelming majority of governments have already adopted policies to affect rates and patterns of internal migration or the configuration of their rural and urban populations. However, recent reviews of these policies suggest they have been only partially successful. Apparent policy deficiencies are reviewed and possible remedies suggested in regard to the need for intervention, the scope of policies, their objectives, instruments, and evaluation.     

Problems concerning population distribution in China]

Questions concerning the spatial distribution of the population of China are explored. It is noted that over 40 percent of the population is concentrated in the coastal southeast and that the highest density of population is found between the Yangtze and Pearl rivers. The measures taken by the government to improve population distribution are described, with particular emphasis on controls of migration to urban areas.     

Elementary models for population growth and distribution analysis

A version of the Lotka-Volterra interaction model is adapted to describe population growth and migration processes in a two-region system. The regions are identified as a metropolis and its non-metropolitan hinterland. Several conditions on growth and migration regimes are imposed. The time behavior of the systems are analyzed, noting especially situations where total depopulation or population explosion eventually occur in one or both populations. Neither growth control nor migration control alone results in a condition of long-run stability in both regions. If at least a momentary condition of zero growth is achieved in both regions, it is possible to maintain finite populations if each population follows a logistic natural growth process and migration flow is proportional to the volume of interaction. It is necessary also that the natural increase limitation is strong relative to migration rates. This result holds even if one population has a net migration advantage over the other.     

四川省人口区域分布与区域经济发展

四川省人口区域分布与中国人口分布有极相似之处:东密西疏。这种不平衡的分布有它的规律性,必然性,靠单方面的人为的力量改变这种分布不均是困难的。这种人口的分布影响到了区域经济的发展。认识到这种人口分布的客观性和规律性,才能正确引导川西经济的可持续发展。     

新疆维吾尔族人口的空间分布与变动

新疆维吾尔自治区地处西部边陲,是一个拥有47个民族成分的大家庭,占全国总面积的1/6。维吾尔族是这个大家庭的一员,也是其中人口最多的民族。该民族的形成与发展经历了漫长的历史时期,人口的空间分布状况与变动情况也有其独特的规律性和特点。尤其是新中国成立后50年来,维吾尔族人口发生了巨大的变化。下面我们就来用定性和定量两方面来分析新疆维吾尔族人口的空间分布与变动情况。     

Retrospective information on health status and its application for population health measures

Healthy life expectancies are almost always calculated by using health data from cross-sectional surveys. This type of calculation is done partly because data from longitudinal surveys are not always available, and when they are available, they are collected at intervals that are longer than one year. In such cases, collecting health information retrospectively for the years skipped by the survey is useful. The main purpose of this paper is to show how retrospective health information can be used to estimate life expectancies in different health states. Healthy life expectancies are estimated with and without using data on retrospective health information, and the corresponding estimates are compared. The two sets of estimates are similar. We conclude that retrospectively assessed health information based on a one-year recall period can be used to estimate years of life in various health states and that estimates based on such information will closely approximate estimates based on concurrent health information.     

Immigrant School Segregation in Sweden

Recent research has shown that there is a substantial skill difference in Sweden between natives and second-generation immigrants. The objective of this study is to find out whether there exists a relationship between immigrant school segregation and the individual’s human capital. The variation in immigrant concentration rate between cohorts within a school generally does not affect the individual’s human capital outcome. However when estimating specific peer influences between different immigrant groups (first-generation immigrants, second-generation immigrants with two foreign-born parent and second-generation immigrants with one foreign-born parent) the study shows three major findings. First, for men (both natives and second-generation immigrants) there is a general negative effect of having a large share of first-generation immigrant schoolmates. Second, for both men and women a large share of schoolmates with a completely foreign background (non-native parents) has a negative influence on the Swedish grades of second-generation immigrants with two foreign-born parents. Third, for men there seem to exist specific and positive peer influences within the groups of second-generation immigrants with either one or two foreign-born parents.     

Residential Segregation in the Mid-Sixties

Special censuses conducted by the Bureau of the Census at the request and expense of local governments provide current statistics for many large cities which are compared with corresponding data from the1960 Census. An analysis was made of the changes in the racial composition of the cities, and of the areas within the cities (defined by census tracts) which had a high concentration of Negro population in 1960 for ten cities of 100,000 or more population at mid-decade.As in the 1950-60 period, Negroes continue to move into the central cities of metropolitan areas while white persons continue to move out to the suburbs at a faster rate, and this results in net declines in the populations of the cities. The proportion of nonwhite persons living in areas of high Negro concentration has remained about the same or increased slightly in a majority of the cities, while in a few (such as Cleveland, Rochester, and Raleigh) this proportion has declined; that is, relatively more Negroes in these cities now live outside the ghetto neighborhoods. When the racial composition of the ghettos is examined, however, a higher proportion of the residents are now Negro when compared to 1960 in each of the ten cities.Thus, the concentration of Negroes in ghetto areas has shown little change, but the trend of white persons moving away from the Negro neighborhoods, either to other parts of the cities or to the suburbs, has increased sharply, and this has tended to polarize the Negro and white populations within large cities.     

Stability over time in the distribution of population forecast errors

A number of studies in recent years have investigated empirical approaches to the production of confidence intervals for population projections. The critical assumption underlying these approaches is that the distribution of forecast errors remains stable over time. In this article, we evaluate this assumption by making population projections for states for a number of time periods during the 20th century, comparing these projections with census enumerations to determine forecast errors, and analyzing the stability of the resulting error distributions over time. These data are then used to construct and test empirical confidence limits. We find that in this sample the distribution of absolute percentage errors remained relatively stable over time and data on past forecast errors provided very useful predictions of future forecast errors.     

On the relationship between household composition and population age distribution

Summary Composition of households by age of head and by age of other household members has recently been presented in a convenient algebraic expression, the household composition matrix. It has been shown that this matrix operates as a linear transformation from the vector of household distribution by age of head to the vector of population age distribution. A further analysis will show that the first row of the matrix may be interpreted as representing a vector of average household fertility rates. If the linear relationship between household and population distributions is fully implemented, then a relationship between household fertility and the size of the youngest age group can be derived. If w is the population age distribution and w (1) is the number of persons in the youngest age group, then: where α is the first row of the household composition matrix with its first element eliminated, C is the household composition matrix with its first row and first column eliminated, and Ψ is the vector w with its first element, w (1) eliminated. Extension of this result will enable simultaneous projection of population and households, suitable for computer application to conventional five-year age groups.     

On the rational distribution of Chinese population]

In 1949, the population distribution in China was characterized by the following distinct features. First, it was unbalanced, with high density in the eastern regions, in the plains, and in areas adjacent to railroads, river navigation routes and other transportation axes. Low population density was found in the western regions, mountainous regions, and areas far from transportation routes. Second, Hans were largest in number and distributed throughout the country, with major concentration in the eastern regions, while the minorities constituted about 10% of the total population and were distributed mainly in the far southwestern and northwestern areas. Third, over 89% of the 540 million of the population was distributed in rural areas while only about 10% in towns and cities, with high densities in some coastal cities. During the past 3 decades, the unbalanced nature of China's population has remained basically unchanged. This can be attributed to factors relating to natural conditions and resources, productivities, socioeconomic conditions, and technological development in different regions. In order to achieve a rational distribution of the Chinese population the following measures should be taken: 1) controlling the birth rate of the Hans and increasing the population of minorities; 2) moving the population of the dense areas to the border provinces in the western regions to develop their natural resources and to elevate the living standards; 3) modernizing the rural areas; 4) strictly controlling the industrial developments of large cities and their population growth; and 5) strictly restricting the unplanned migration of population to and from cities.     

Social Anomie and Racial Segregation in South Africa

The concept of anomie is one of the classics of sociological theory. Developed by scholars such as Emile Durkheim and Robert K. Merton, the concept refers to the absence of clear social norms and values and to a lack of sense of social regulation. However, whereas Merton focused on features of relative deprivation that cause anomie, Durkheim was primarily interested in the link between rapid social change and social anomie. According to the latter, normative regulation is threatened with being undermined and people are likely to lack the social and psychological means for adjustment in times of rapid social change. Drawing on survey data from the South African General Household Survey polled in 2002, the article examines the ethnical differences in levels of social anomie in the South African society. In order to do so, we, first, place the South African levels of anomie into comparative context. In a second step, we look at the race specific levels of anomie. Third, we investigate whether the differences in anomie between the races are related to the still existing socio-economic inequalities or whether race can be regarded as an independent factor that impacts on anomie. Finally we scrutinize to what extent socio-economic factors account for different levels of anomie within the races.     

Housing Tenure and Residential Segregation in Metropolitan America

Homeownership, a symbol of the American dream, is one of the primary ways through which families accumulate wealth, particularly for blacks and Hispanics. Surprisingly, no study has explicitly documented the segregation of minority owners and renters from whites. Using data from Census 2000, this study aims to fill this gap. Analyses here reveal that the segregation of black renters relative to whites is significantly lower than the segregation of black owners from whites, controlling for relevant socioeconomic and demographic factors, contrary to the notion that homeownership represents an endpoint in the residential assimilation process. The patterns for Hispanics and Asians conform more to expectations under the spatial assimilation model. The findings here suggest that race and ethnicity continue to be as important in shaping residential segregation as socioeconomic status, and raise concerns about the benefits of homeownership, particularly for blacks.     

Preliminary analysis of population distribution in Beijing, Tianjin, and Tangshan]

The author analyzes population distribution in Beijing, Tianjin, and Tangshan, China. According to the author, the population distribution of these areas is characterized first by high population density. The forms of distribution are found to be many and varied: network distribution, cluster distribution, star distribution, bar distribution, and point distribution in rural residential areas. The ratio of urban population to rural population is high, but the distribution is concentrated. The factors affecting population distribution are natural environment, economic development, and historical heritage.     

关于中国教育性别隔离的分析

文章以平方根指数作为衡量性别教育不平等的工具,得出以下结论:一、1990年至今,中国教育性别隔离总体呈下降趋势,城乡差异依然显著;二、地区教育性别隔离程度从高到低为东部,西部和中部;三、就各教育层次来看,教育性别隔离下降主要来自义务教育的贡献,高等教育阶段女性受教育机会相对更平等.进一步的分析发现,教育性别隔离状况与经济发展水平及人均教育经费并不相关,与人均受教育年限和出生性别比有一定关系.     

How often do australians move? alternative measures of population mobility

Conventional census-based measures of population mobility are conceptually abstruse, ignore multiple moves and obscure the diversity of human migration experience. This paper explores three alternatives and outlines their strengths and limitations. Application of life table techniques to convert transition rates to migration expectancies generates measures that are more readily understood, automatically standardizes for age and enables the timing of mobility to be analysed methodically. Data on movement frequencies and residence duration provide new perspectives indicating substantial chronic mobility and significant differences between frequent movers and long term stayers. A number of simple summary statistics are proposed to supplement transition rates.
