Improvements in Life Expectancy: 1960–1995 an Exploratory Analysis

Human history observed significant changes in life expectancy over the last three and half decades (1960–1995). This study attempts to explore the determinant factors behind improvements in life expectancy in most of the countries in the Post World War II period. In this context the study estimates a double logarithmic convergence type model where the dependent variable is relative change of life over the period and the explanatory variables are initial per capita real gross domestic product, initial per capita calorie intake as percentage of requirement, adult literacy rate at the initial point of time, and initial physician per thousand of population. The study estimates different variants of the basic model. Female population has been treated separately. All estimates have been offered for three broad income groups low, middle and high. An attempt is also made to take into account the effects of some public health measures such as access to safe drinking water and access to sanitation.     

Trends in life expectancy in wellbeing

Objectives: This paper describes anddiscusses trends in life expectancy inwellbeing between 1989 and 1998.Methods: Data on wellbeing by theBradburn Affect Balance Scale is obtained fromthe Netherlands Continuous Health InterviewSurveys for the calendar years from 1989 to1998. Using Sullivan's method, life expectancyin wellbeing is calculated.Results: For males at the age of 16, lifeexpectancy in wellbeing increases significantlyfrom 52.7 years in 1989 (90.1% of the totallife expectancy) to 54.4 years in 1998(90.8%). This increase is almost completelycaused by the increase in total lifeexpectancy. For females at the age of 16, lifeexpectancy in wellbeing raises significant from54.4 years in 1989 (84.1%) to 56.2 years in1998 (86.3%). This increase is almostcompletely caused by a decrease in the numberof years in a state of distress.For both males and females at the age of 65,the significant increase of life expectancy inwellbeing exceeds the increase in total lifeexpectancy and is mainly caused by the decreasein number of years in distress.Conclusion: Contrary to life expectancyin good perceived health and to disability freelife expectancy – which show a decreasing trend– the overall wellbeing of the population isincreasing. It seems that aspects in human lifethat contribute to wellbeing or quality of lifeother than physical health are gaining inimportance. This makes life expectancy inwellbeing a less appropriate instrument tomonitor changes in population health, but auseful instrument to measure population qualityof life.     

Intercountry adoption in the new millennium; the ``quiet migration' revisited

Intercountry adoption is not usually seen as a matter for demographers, although articles in the International Migration Review have looked at international adoption as a migratory process. This article outlines the author's estimate of the number of intercountry adoptions world-wide, using data recorded by 18 receiving states in the 1990s. Data from selected receiving countries are used to estimate the number of adoptions from states of origin. Comparisons are made with data for 14 countries over the period 1980–89 collated by Kane (1993).The global estimate of at least 32,000 adoptions in 1998 is much higher than thenumbers usually cited and suggest a rise of fifty percent over the previous decade.Total numbers are dominated by adoptions to the United States and from China andRussia. However standardisation against population size or number of live birthssuggests that the highest rates among receiving states are to be found in Scandinavia,while the highest rates for states of origin are in countries of Eastern Europe, followedby Korea – countries typified by very low birth rates. The article ends with a discussion of the implications of these findings for the future of international controls and the implementation of the 1993 Hague Convention.

The making of a ghetto: Spatially concentrated poverty in New York City in the 1980s

In recent years a debate has arisen over which of two mechanisms — class selective household mobility or spatially focused increases in poverty — has been the driving force in concentrating poverty in certain inner-city neighborhoods. This paper utilizes a multivariate analysis to identify the processes underlying areal income-class transition in New York City during 1978–1987, and the areal characteristics that predict a consistent path of change. By anchoring the analysis at the level of the individual housing unit, this study disentangles the competing mechanisms of poverty concentration and demonstrates that both selective mobility and shifts in income class contribute to areal income-class transition, but that the latter mechanism accounts for a greater amount of change. Further, after controlling for the proportion of minority residents and public housing units in the area, the results show that location in poor areas is associated with poor in-movement, nonpoor out-movement, and downward shifts in the income class among long-term residents. These mutually reinforcing processes lead to continued decline in extreme- and high-poverty areas, while processes in the opposite direction sustain the economic vitality of low-poverty areas.An earlier version of this paper was presented at the 1992 meetings of the Population Association of America in Denver, Colorado.     

A cohort analysis of the timing of first birth and fertility in Ghana

This paper examines the nature of the inverse association between age at first birth and fertility across successive generations of Ghanaian women. Within the context of enhanced non-marital opportunities for contemporary women and declining fertility, we develop a rationale for and test the hypothesis that in a medium fertility environment as currently found in Ghana, the effect of age at first birth on fertility becomes more important than ever before. Five birth cohorts were identified (1938–1944; 1945–1949;1950–1954; 1955–1959; 1960–1964)from a merged file of the 1988, 1993 and 1998 Ghana Demographic and Health Surveys. The analyses were restricted to women over 35 years old at the time of the surveys, which allowed us to use current parity as a reasonable proxy for completed fertility. Preliminary results suggest that women who had first births early tend to have a higher number of births than those whose first births occur late, regardless of birth cohort. In multivariate analyses, the effect of age at first birth as a determinant of fertility was found to be more substantial among later cohorts. The implications of the findings are discussed.     

Temporal variation in the relationship between environmental demands and well-being: a panel analysis of developed and less-developed countries

This study assesses the degree to which the relationship between the environmental demands of countries (measured as ecological footprint per capita) and well-being (measured as life expectancy) has changed over the last several decades (1961–2007) and whether the nature and extent of these changes differ between developed and less-developed countries. Pooled ordinary least squares regression results indicate that decoupling has occurred among developed countries, where the relationship between ecological footprint and life expectancy weakened substantially over time, becoming negative in later years. In less-developed countries, the relationship has intensified substantially, with the effect of ecological footprint on life expectancy becoming stronger over time. Fixed-effects regression results provide similar results for developed countries but indicate slight decoupling between increases in ecological footprint and life expectancy among less-developed countries. The implications of these results are discussed in the context of contraction and convergence approaches to sustainability.     

The impact of migration on the nonmetropolitan population age structure, 1960–1990

In this paper we examine the short-run impact of migration on the age composition of nonmetropolitan areas. Changes in age structure can have important consequences at the local level, and the influence of migration is particularly notable because it is highly age-graded, with different migration patterns found in various types of nonmetropolitan communities. Here we compare the impact of migration on age structures in metropolitan and nonmetropolitan areas across the last three decades. Within nonmetropolitan areas we also compare counties with colleges, commuting counties, agricultural counties and retirement counties. We conclude that several factors influence the impact of migration on age structure. Impacts will be greater in smaller than in larger population groups, and in areas that specialize in economic functions that impinge on a particular age group. But in general, migration adds young people to metropolitan areas and older people to nonmetropolitan areas. Differential impacts may be lessened in periods, such as 1970–80, when substantial population redistribution was underway. Nevertheless, prior and present fertility and mortality trends, and the cumulative history of migration well exceed the impact of migration on age in any ten-year interval.Abbreviations Metro Metropolitan - Nonmetro Nonmetropolitan An earlier version of this paper was presented at the annual meeting of the Western Regional Science Association, Wailea, Hawaii, 22 February 1993.     

Changing causes of death and the sex differential in the USA

This paper examines the sex differential in US life expectancy, the changes in this differential over the past 25 years and into the near future, and the apportionment of these differences among the leading causes of death. Movements in the sex differential over the years 1960–1985 were largely determined by changes in the accidents and violence and heart disease causes of death. The use of the life expectancy measure emphasizes the importance of those causes of death that impact most severely at younger ages. The historical analysis is extended through projections of life expectancies by sex. In the projections increased cancer mortality among males contributes to a widening differential, tempered by greater progress against heart disease for males.This is a revised version of a paper presented at the meetings of the Population Association of America, 30 April-2 June 1992, in Denver, Colorado.     

Causality Chains in the International Migration Systems Approach

Research into international migration lacks a commonly accepted theoretical framework, which would facilitate the accumulation of knowledge. This article aims to be a first attempt to construct such a framework and to incorporate causalities in the international migration systems approach. The author presents a theoretical framework in which four groups of factors acting on international migration are distinguished: economic, social, political and “linkages.” The causalities in this framework are derived from different international migration theories. The various positions of these whole theories within the framework are shown as causality chains. In a way, these causality chains form the time dimension of an international migration system

Migration intentions and behavior: Decision making in a rural Philippine province

The relationship between intentions and behavior is basic to micro-level migration decision research. This study, set in the rural Philippine province of Ilocos Norte, provides evidence on personal and structural background factors and value-expectancy perceptions of place utility that predict migration intentions and behavior. Separate analyses are conducted for general intentions to move and for destination-specific migration intentions, the latter pertaining to both internal migration (Manila) and international migration (Hawaii). Logistic regression analyses applied to the data from a 1980–82 longitudinal survey show that the empirical models are highly efficient in explaining migration intentions but less efficient in explaining actual migration behavior in this Third World setting. Important explanatory variables for both intentions and behavior include family pressure to move or stay, family auspices at alternative destinations, money to move, prior migration experience, and the life cycle stage (marital status and age). However, the determinants of internal and international migration behavior are not the same. The data only partially support the Ajzen and Fishbein (1980) position that intentions are the dominant determinant of behavior. Personal and structural background factors are shown to exert independent direct effects on migration behavior.Revised version of a paper presented at the annual meeting of the Population Association of America, Minneapolis, Minnesota, May 2–5, 1984.

Mobility plans and mobility behavior: Convergences and divergences in Thailand

Using Thai data, this paper develops and tests a model of rural-urban mobility behavior in a context dominated by high levels of circular rural-urban mobility. With mobility plans and mobility behavior measured in analogous ways, a close correspondence between mobility plans and mobility behavior is found. In spite of this close correspondence, however, multivariate analysis shows that past mobility behavior—rather than mobility plans—is the most important predictor of subsequent mobility. Where experience with a given type of behavior is abundant, prior behavior may often be the best predictor of subsequent behavior, but where experience with a given type of behavior is scarce, behavioral intentions may be a more relevant explanatory variable.The research reported here was funded by the Rockefeller and Ford Foundations' Research Program on Population and Development Policy (RF 77065; Allocation 164).

On testing Easterlin's hypothesis using relative cohort size as a proxy for relative income

Measures of Canadian fertility (total fertility rate and fifteen-year age-specific fertility rate F_15–29) and relative cohort size (population aged 30–64 years divided by population aged 15–29 years) show a close co-movement between 1940 and 1976 but record a marked departure since then. The application of cointegration techniques to these series (1921–1988) shows that they do not form an equilibrium relationship even over the period 1940–1976. Contrary to the expected relationship between relative cohort size and relative income, income data by age groups show that there is no tight relationship between them. The absence of an equilibrium relationship between relative cohort size and fertility, therefore, does not necessarily imply that Easterlin's hypothesis is false.I would like to thank Paul Maxim for allowing me to use his data set for this analysis. My thanks are also due to Peter Smith and three anonymous referees for their constructive comments on this work.     

Evaluating the local impacts of recent immigration to California: Realism versus racism

Although past migration was often viewed with suspicion the implicit assumption was that new migrants would fill the jobs in the growing cities and contribute to the national wealth. There are those who still subscribe to the view that continuing migration will increase national wealth, indeed that new migrants are the work horses of prosperity. There is another view however, which focuses on the local impacts of migration. This view suggests that the migrations of the late twentieth century are in a different context and create substantial burdens on local communities and states. It may be too, that the mass migrations of the late twentieth century will lead to a new pattern of social exclusion, polarization and a new ethnic under-class. The analysis of recent migration in California documents the extent to which that migration is made up of very low skill, low income, and dependent groups and has the potential to create significant local dependency burdens.     

中国老年人口迁移的选择性

本文利用2005年全国1％人口抽样调查数据,描述老年人口跨地市级迁移的结构特征。研究发现,我国老年人口依旧把经济发达地带、大城市作为主要迁入地,与青壮年人口迁移方向产生同构。城乡老年迁移人口在迁移动机上存在很大的差别,城市户籍老年迁移人口受家庭因素驱动更大,农村户籍老年人的迁移原因更多元。从对迁入地的影响来看,国内老年迁移人口的迁入地过于集中,将对迁入地的社会医疗服务设施等构成巨大的压力。     

中国省际人口迁移与东部地带的经济发展:1995～2000

本文主要考察了 1 995～ 2 0 0 0年间中国省际人口迁移与东部地带经济发展的关系 ,发现省际迁移人口 (外来劳动力 )已成为推动东部地带经济发展不可替代的重要因素。正是大量外来劳动力的迁入 ,弥补了东部地带本地劳动力供给的不足 ,推动东部地带的GDP增长了 1 0 %以上 ,对东部地带GDP增长的贡献度几乎达 1 5 %。而且在东部地带 ,越是省际人口迁移吸引中心 ,迁入人口规模越大 ,迁入的外来劳动力对推动迁入地经济发展的作用和贡献就越大。     

Modeling interregional migration flows: Continuity and change

This paper addresses the question of how to formally represent the spatial structure of an observed origin‐destination‐specific pattern of interregional migration flows. Such a representation allows an analyst to compare the spatial structures of different migration regimes and contrast their changes over time. It also facilitates the indirect estimation of migration flows, in the absence of such data, by allowing the analyst to impose a particular age or spatial structure when observed flow data are inadequate, partial, or completely nonexistent. In this paper, we focus on the level and allocation aspects (or the generation and distribution components) of age‐specific interregional migration flows. We find that over time these flows exhibit strong regularities that can be captured by generalized linear models, which can then be used in situations where data are inadequate or missing to indirectly estimate interregional migration patterns.     

Time preference and labour migration in an OLG model with land and capital

This paper constructs a two-country migration model in the lines of Galor (1986), in which the world population consists of individuals of two types who have different time preferences. Production uses three inputs: mobile labour, immobile capital and land. It is shown that both countries are necessarily inhabited by agents of both types and exhibit equal density of population and equal interest rate at the steady state equilibrium of the integrated economy. The steady state welfare implications of international labour migration are studied.This paper has been written during Philippe Michel's visit at CORE, September 1994.
