Internal migration age patterns and the transition to adulthood: Australia and Great Britain compared

Life-course transitions are important drivers of mobility, resulting in a concentration of migration at young adult ages. While there is increasing evidence of cross-national variations in the ages at which young adults move, the relative importance of various key life-course transitions in shaping these differences remains poorly understood. Prior studies typically focus on a single country and examine the influence of a single transition on migration, independently from other life-course events. To better understand the determinants of cross-national variations in migration ages, this paper analyses for Australia and Great Britain the joint influence of five key life-course transitions on migration: (1) higher education entry, (2) labour force entry, (3) partnering, (4) marriage and (5) family formation. We first characterise the age profile of short- and long-distance migration and the age profile of life-course transitions. We then use event-history analysis to establish the relative importance of each life-course transitions on migration. Our results show that the age structure and the relative importance of life-course transitions vary across countries, shaping differences in migration age patterns. In Great Britain, the strong association of migration with multiple transitions explains the concentration of migration at young adult ages, which is further amplified by the age-concentration and alignment of multiple transitions at similar ages. By contrast in Australia a weaker influence of life-course transitions on migration, combined with a dispersion of entry into higher education across a wide age range, contribute to a protracted migration age profile. Comparison by distance moved reveals further differences in the mix of transitions driving migration in each country, confirming the impact of the life-course in shaping migration age patterns.     

Migration and retirement in the life course: an event history approach

Migration at older ages is commonly explained by reference to the search for greater amenity, and subsequently by the onset of greater dependency, but the links between mobility and specific life course transitions have rarely been articulated. We aim to establish the timing of migration in relation to retirement from the labour force, and to determine how its intensity varies around the retirement event. We also seek to identify how household and individual characteristics shape the propensity and timing of migration, differentiating moves according to distance and with particular attention to the characteristics of the spouse. Data are drawn from the first six waves of the Household, Income and Labour Dynamics in Australia survey, a nationally representative panel study covering the period 2001–2006. Migration events are identified relative to retirement and event history methods are employed to establish the characteristics predisposing households to relocate around retirement. Results demonstrate that retirement acts as a trigger to migration but the propensity to move falls as retirement age rises and the hazard is increasingly concentrated in the year retirement occurs. Within this framework the presence, health, education and retirement status of a spouse exert a significant influence on the likelihood of migration, though with different effects for long and short distance moves. Results highlight the importance of variations in underlying life-course trajectories in shaping retirement migration and demonstrate that only a minority of moves at ages 55–69 are directly associated with retirement, underlining the need for caution when identifying retirement migration using age as a proxy measure.     

The Correspondence Between Fertility Intentions and Behavior in the United States

Using data from the 1979 National Longitudinal Survey of Youth, we describe the correspondence between intended family size and observed fertility for US men and women in the 1957–64 birth cohorts. Mean fertility intentions calculated from reports given in the mid‐20s modestly overstate completed fertility. But discrepancies between stated intent and actual fertility are common—the stated intent at age 24 (for both women and men) is more likely to miss than to match completed fertility. We focus on factors that predict which women and men will have fewer or more children than intended. Consistent with life‐course arguments, those unmarried, childless, or (for women) still in school at approximately age 24 were most likely to underachieve their intended parity (i.e., had fewer children than intended at age 24). We discuss how such discrepancies between intentions and behavior may cumulate to produce sizable cross‐group fertility differences.     

On the Determinants of Mortality Reductions in the Developing World

This article presents and critically discusses evidence on the determinants of mortality reductions in developing countries. It argues that increases in life expectancy between 1960 and 2000 were largely independent of improvements in income. The author characterizes the age and cause‐of‐death profile of changes in mortality and assesses what can be learned about the determinants of these changes from the international evidence and from country‐specific studies. Public health infrastructure, immunization, targeted programs, and the spread of less palpable forms of knowledge all seem to have been important factors. Finally, the article suggests that the evolution of health inequality across and within countries is intrinsically related to the process of diffusion of new technologies and to the nature of these new technologies, public or private.     

Variations in Kinship Networks Across Geographic and Social Space

This article analyzes variations in interaction with non‐coresident adult kin based on comparable cross‐national surveys conducted in 2001 in 27 countries. The two main dimensions of kin contact are considered: (1) overall levels and (2) the relative emphasis given to contacts with primary kin (parents, adult children, siblings) and secondary kin (aunts, cousins, in‐laws). Age‐adjusted variations in kin contact between countries are much greater than those within countries. These results do not confirm the commonly hypothesized existence of well‐defined family system boundaries in Europe arising from historical factors. The similarity of patterns of countries outside Europe with European countries with which they have historical ties suggests cultural factors are important in explaining interaction with kin, whereas welfare regimes appear to have little explanatory value. Within Europe, kin contact levels are more strongly related to a north/south divide than to indicators of economic development or religiosity. The findings suggest that neither of the extreme assumptions—homogenizing pressures toward a nuclear family model or persistent well‐defined groupings arising from historical contexts—can be substantiated. Rather, there is a continuum in family behaviors over a substantial range, related to a number of explanatory factors.     

A New Method for Determining Why Length of Life is More Unequal in Some Populations Than in Others

Why is there greater variability in individual longevity in some populations than in others? We propose a decomposition method designed to address that question by quantifying the effects of population differences in the spread, allocation, and timing of the principal causes of death. Applying the method to the United States and Sweden, we find that spread effects account for about two-thirds of the greater variance in age at death among American adults, meaning that two-thirds of the U.S.-Sweden difference would persist if the two countries differed only with respect to within-cause variance among adults. The remainder of the difference is due largely to allocation effects, with the greater incidence of homicides and fatal traffic accidents alone accounting for more than one-fourth of the greater variance in age at death among adults in the United States.     

Inequality in Life Spans and a New Perspective on Mortality Convergence Across Industrialized Countries

The second half of the twentieth century witnessed substantial convergence in life expectancy around the world. We examine differences in the age pattern of mortality in industrialized countries over time to show that inequality in adult life spans, which we measure with the standard deviation of life table ages at death above age 10 years, S₁₀, is increasingly responsible for the remaining divergence in mortality. We report striking differences in level and trend of S₁₀ across industrialized countries since 1960, which cannot be explained by aggregate socioeconomic inequality or differential external‐cause mortality. Rather, S₁₀ reflects both within‐ and between‐group inequalities in life spans and conveys new information about their combined magnitudes and trends. These findings suggest that the challenge for health policies in this century is to reduce inequality, not just lengthen life.     

Internal Migration and Development: Comparing Migration Intensities Around the World

Migration is the principal demographic process shaping patterns of human settlement, and it serves an essential role in human development. While progress has been made in measuring international migration, internal migration statistics are as yet poorly developed in many countries. This article draws on a repository of data established under the IMAGE (Internal Migration Around the GlobE) project to address this deficit by constructing the first comprehensive league table of internal migration intensities for countries around the world. We review previous work, outline the major impediments to making reliable comparisons, and set out a methodology that combines a novel estimation procedure with a flexible spatial aggregation facility. We present the results in the form of league tables of aggregate crude migration intensities that capture all changes of address over one‐year or five‐year intervals for 96 countries, representing four‐fifths of the global population. Explanation for the observed differences has been sought, inter alia, in historical, structural, cultural, and economic forces. We examine the links between development and migration intensity through simple correlations using a range of demographic, economic, and social variables. Results reveal clear associations between internal migration intensities and selected indicators of national development.     

Age-Specific Variation in Adult Mortality Rates in Developed Countries

This paper investigates historical changes in both single-year-of-age adult mortality rates and variation of the single-year mortality rates around expected values within age intervals over the past two centuries in 15 developed countries. We apply an integrated hierarchical age-period-cohort—variance function regression model to data from the human mortality database. We find increasing variation of the single-year rates within broader age intervals over the life course for all countries, but the increasing variation slows down at age 90 and then increases again after age 100 for some countries; the variation significantly declined across cohorts born after the early 20th century; and the variation continuously declined over much of the last two centuries but has substantially increased since 1980. Our further analysis finds the recent increases in mortality variation are not due to increasing proportions of older adults in the population, trends in mortality rates, or disproportionate delays in deaths from degenerative and man-made diseases, but rather due to increasing variations in young and middle-age adults.     

Determinants of Educational Attainment in Rural Thailand: A Life Course Approach

Using data from rural Thailand, we examine the determinants of educational attainment of school-age children. We organize our analysis around three central principles of the life course perspective: the embeddedness of lives in historical time and place, linked or interconnected lives, and the timing of lives. We examine these principles using comparisons within cohorts and between cohorts. We find that educational attainment is related to a combination of factors related to each of these principles. Specifically, despite a serious economic downturn occurring midway through our study, we nonetheless found that educational levels were higher following the downturn than preceding it. Interconnections to parents and siblings also affected educational outcomes, as did the timing of life events such as migration, marriage, and childbearing. For the latter, mother??s education and migration both positively affected educational attainment. For the former, having more siblings, both those in the household and those migrating, reduced education.     

Family Location and Caregiving Patterns from an International Perspective

We conduct a cross‐national econometric analysis of intra‐family location and caregiving patterns. Using European data, we first assess, from an international perspective, the relationship between family structure and the geographic proximity between adult children and their parents. We then examine whether differences in family structure are related to the amount of informal care adult children provide to their elderly parents. Lastly, we look for cross‐country differences in family location and caregiving patterns, and interpret observed differences in terms of heterogeneous institutional solutions to elderly care. Our results not only provide a new empirical perspective on the geography of the family, but also provide insights into how family‐related and institutional factors shape patterns of time transfers from adult children to elderly parents.     

Interrelationships Between Childbearing and Housing Transitions in the Family Life Course

Research has examined the effect of family changes on housing transitions and childbearing patterns within various housing types. Although most research has investigated how an event in one domain of family life depends on the current state in another domain, the interplay between them has been little studied. This study examines the interrelationships between childbearing decisions and housing transitions. We use rich longitudinal register data from Finland and apply multilevel event history analysis to allow for multiple births and housing changes over the life course. We investigate the timing of fertility decisions and housing choices with respect to each other. We model childbearing and housing transitions jointly to control for time-invariant unobserved characteristics of women, which may simultaneously influence their fertility behavior and housing choices, and we show how joint modeling leads to a deeper understanding of the interplay between the two domains of family life.     

Living Alone over the Life Course: Cross-National Variations on an Emerging Issue

The increasing proportion of persons living alone has come to be emblematic in many ways of modern Western societies because it represents the importance conceded to the individual and to individual goals at the expense, basically, of the family. Solo living has been interpreted within the context of changing values and preferences, changing personal and conjugal realities, and the changing work contexts so often associated with the Second Demographic Transition. We know little about patterns and trends in living alone over the life course in much of the world because most research to date has concentrated on regional and national portrayals or on living arrangements in later life. This study provides a systematic look at the differences in living alone by age and sex in 113 countries. Our aim is to understand the extent to which behavior differs around the world and the implications this has for society. We also examine the relationship between trends in living alone and levels of human development. Results are taken from three massive datasets: census and survey microdata from IPUMS-international, Demographic Health Surveys, and EU-Labor Force Surveys.     

The European Commission on Factors Influencing Labor Migration

A controversial issue in discussions on enlargement of the European Union beyond its existing membership of 15 countries is the migration flows that admission of new members could generate. Given major differences in income and wage levels between the EU states and the candidates for membership, casual theorizing suggests that the potential for massive international migration is very high. The fact that such migration has thus far been of modest size by most plausible criteria is attributed to the restrictive policies of the potential destination countries, policies that reflect national interests, in particular protection of labor markets, as perceived by voting majorities. With accession to membership in the EU this factor is removed: a cardinal principle of the Union, established by treaty, is the free movement of persons, including persons seeking gainful employment. The factors governing migratory movements between member states then come to resemble those that shape internal migration. This should facilitate analysis and forecasting. A clear sorting‐out of the relevant forces affecting such “internal” migration remains of course an essential precondition for success in that task. An “Information note,” entitled The Free Movement of Workers in the Context of Enlargement, issued by the European Commission, the EU's Executive Body, on 6 March 2001, presents extensive discussion of relevant information, opinion, and policy options concerning its topic. (The document is available at « http://europa.eu.int/comm/enlarge‐ment/docs/pdf/migration_enl.pdf ».) An Annex to the document. Factors Influencing Labour Movement, is a lucid enumeration of the factors migration theory considers operative in determining the migration of workers and, by extension, of people at large, that is likely to ensue upon EU enlargement. This annex is reproduced below. As is evident from the catalog of factors and their likely complex interactions, making quantitative forecasts of future migration flows, envisaged primarily as originating from countries to be newly admitted to the EU and destined for the countries of the current EU15, is exceedingly difficult. This is reflected in disparities among the existing studies that have made such forecasts. Yet there appears to be a fair degree of agreement that major increases in migration are unlikely, suggesting that the overall effect on the EU15 labor market should be limited. Typical forecasts (detailed in the Information note cited above) anticipate that in the initial year after admission, taken to be 2003, total migration from the eight prime candidate countries (the Czech Republic, Hungary, Poland, Slovakia, Slovenia, Estonia, Latvia, and Lithuania: the “CC8”) might amount to around 200,000 persons, roughly one‐third of which would be labor migration. According to these forecasts, the annual flow will gradually diminish in subsequent years. After 10 to 15 years the stock of CC8 migrants in the EU15 might be on the order of 1.8 to 2.7 million. The longer‐run migration potential from the candidate countries would be on the order of 1 percent of the present EU population, currently some 375 million. (The combined current population of the CC8 is 74 million.) Such predictions are in line with the relatively minor migratory movements that followed earlier admissions to the EU of countries with then markedly lower per capita incomes, such as Spain and Portugal. The geographic impact of migration ensuing from enlargement would, however, be highly uneven, with Germany and Austria absorbing a disproportionately large share. Accordingly, and reflecting a prevailing expectation in these two countries that enlargement would have some short‐run disruptive effects on labor markets, some of the policy options discussed envisage a period of transition following enlargement—perhaps five to seven years—during which migration would remain subject to agreed‐upon restrictions.     

The life course of Canadian women: An historical and demographic analysis

The life course of Canadian women over the last 100–150 years is examined, using data extracted from census and vital statistics publications. Cohort analysis and synthetic cohort analysis are employed as means to focus upon changes in the occurrence and timing of age-related life course transitions related to the family. Three substantive themes emerge: the increased predictability, standardization, and compression in age-related family life course transitions. Major changes and continuities are outlined, as well as implications related to the atypical life course experience of the cohorts of women who produced the “baby boom,” and to the emergence of temporally-related mechanisms of social control.     

European perspectives on healthy aging in women

Using data from the 1994 European Community Household Panel, we compare active life expectancy differentials at age 65 years between women and men in 12 European countries. We seek to explain the extent to which differences are a reflection of gender differentials in life expectancy at 65 years or reflect differences in active life expectancy earlier in life. Considerable variation in the gender differentials in both total and active life expectancies at age 65 years exist within Europe, with some countries experiencing 20% lower life expectancy at age 65 years for men compared to women. Some evidence was found to suggest that gender differentials in active life expectancy may continue from younger ages through to later life.     

The Age Difference Between Spouses: Variations among Developing Countries

Sub-national and cross-national variations in the age difference between spouses are investigated with data from the World Fertility Survey relating to 29 developing countries. Substantial variation within and between countries is evident. Analysis suggests that the relative age of prospective spouses is a factor taken into account in the marriage market. Observed variation in the age difference, within and between countries, cannot be explained as the simple by-product of the random matching of independently determined distributions of men's and women's ages at marriage. Certain age differences are avoided, others chosen more frequently. Preferred age differences appear to differ in the societies studied, however, and this variation can be directly interpreted in terms of two sets of factors: kinship structure and women's roles. The analysis also suggests that demographic determinants of the age difference, in particular age constraints on the pool of possible matches, are of less importance in explaining societal variations than are social structural factors.     

Cross-National Variation in Individual Life Satisfaction: Effects of National Wealth, Human Development, and Environmental Conditions

This study adds to the literature on subjective well-being and life satisfaction by exploring variation in individual life satisfaction across countries. Understanding whether and how individual life satisfaction varies across countries is important because if the goal of development is to increase well-being, we must identify the causes of well-being in different national and regional contexts. Using hierarchical linear modeling techniques, I test the hypothesis that individual well-being does vary across countries, and that national wealth, human development and environmental conditions explain this variation. I also test whether the effects of individual characteristics on life satisfaction (including age, marital status, education, income, employment status, and sex) vary across countries, and which country level characteristics explain these variations. Using individual level data from the World Values Survey, I find that there is significant variation in life satisfaction across countries. There is also significant variation in the slopes of individual predictors of life satisfaction across countries and regions. Regional differences in the effects of individual characteristics on life satisfaction explain most of the between country variation in life satisfaction. This indicates that universal development indicators may not adequately reflect differences in life satisfaction across countries, and that development measurements should better reflect regional differences.

International migration: a global challenge

Trends in international migration are presented in this multiregional analysis. Seven of the world's wealthiest countries have about 33% of the world's migrant population, but under 16% of the total world population. Population growth in these countries is substantially affected by the migrant population. The migration challenge is external and internal. The external challenge is to balance the need for foreign labor and the commitment to human rights for those migrants seeking economic opportunity and political freedom. The internal challenge is to assure the social adjustment of immigrants and their children and to integrate them into society as citizens and future leaders. Why people cross national borders and how migration flows are likely to evolve over the next decades are explained. This report also presents some ways that countries can manage migration or reduce the pressures which force people to migrate. It is recommended that receiving nations control immigration by accelerating global economic growth and reducing wars and human rights violations. This report examines the impact of immigration on international trade, aid, and direct intervention policies. Although migration is one of the most important international economic issues, it is not coordinated by an international group. The European experience indicates that it is not easy to secure international cooperation on issues that affect national sovereignty. It is suggested that countries desiring control of their borders should remember that most people never cross national borders to live or work in another country, that 50% of the world's migrants move among developing countries, and that countries can shift from being emigration to immigration countries. The author suggests that sustained reductions in migration pressure are a better alternative than the "quick fixes" that may invite the very much feared mass and unpredictable movements.     

Men’s career development and marriage timing during a period of rising inequality

Based on data from 1979–1990 NLSY interviews, we investigate the implications of rising economic inequality for young men’s marriage timing. Our approach is to relate marriage formation to the ease or difficulty of the career-entry process and to show that large race/schooling differences in career development lead to substantial variations in marriage timing. We develop measures of current career “maturity” and of long-term labor-market position. Employing discrete-time event-history methods, we show that these variables have a substantial impact on marriage formation for both blacks and whites. Applying our regression results to models based on observed race/schooling patterns of career development, we then estimate cumulative proportions ever married in a difficult versus an easy career-entry process. We find major differences in the pace of marriage formation, depending on the difficulty of the career transition. We also find considerable differences in these marriage timing patterns across race/schooling groups corresponding to the large observed differences in the speed and difficulty of career transitions between and within these groups
