Fertility Decline and Increased Manifestation of Sex Bias in India

This paper argues that expectations - the process of evaluating the chances for future attainment of valued goals in the home community (stay decision) vs. alternative locations (move decision) - along with family norms about migration are major predictors of intention to move, which in turn is a proximate determinant of migration behaviour. Utilizing longitudinal data from the 1992 and 1994 waves of the Thailand National Migration Survey, logistic regression models show that a strikingly different set of expectations, household demographic indicators, and migrant capital factors were significant determinants of migration intentions for men and women; reflecting Thai gender roles. Migration intentions, in turn, predicted more permanent, but not temporary, survival strategy migration behaviour, while low household income predicted temporary but not more permanent migration behaviour. The measure of perceived family migration norms was a powerful determinant of migration behaviour, but the size of migrant networks was not a statistically significant determinant of either migration intentions or behaviour.

Ecological Analyses of Permanent and Temporary Migration Streams in China in the 1990s

Using data from China’s Fifth National Census of 2000, we analyze the dynamics of China’s inter-provincial permanent and temporary migration streams for the 1995–2000 period. The permanent and temporary migration streams are shown to have similar patterns, but the volume of the temporary migration streams greatly outnumbers that of the permanent streams. A human ecological model of migration is proposed and tested, and its results are compared with those of a gravity model of migration. Of the various ecological variables examined in the models, investment levels at destination, and being a coastal province at destination, all have strong effects on migration. The effects of the independent variables are more similar than different with regard to predicting the permanent and the temporary migration streams.     

Postmarital Living Arrangements in Historically Patrilocal Settings: Integrating Household Fission and Migration Perspectives

This study integrates theory and research on household fission (or partition) and migration to better understand living arrangements following marriage, especially in historically patrilocal and primarily agricultural settings. Using panel data from the Chitwan Valley Family Study to analyze the sequential decision-making process that influences men’s living arrangements subsequent to first marriage, we demonstrate the importance of distinguishing among extended family living, temporary migration, and the establishment of an independent household. We find that community economic characteristics, such as access to markets or employment, as well as household wealth affect the initial decision to leave the natal home. Household resources and use of farmland, along with the young men’s own education, media exposure, travel, and marital behavior, influence the decision to make the departure from the natal home permanent. Our findings explain why previous results regarding household fission and those focused on migration have provided such mixed results, and we establish a new framework for thinking about how families and individuals manage living situations.     

On the role played by household registration materials in China's 1982 population census]

The author examines the relationship between the 1982 census and the population registration system in China. Because the household registration data are so complete (they include data on permanent and temporary residence, births, deaths, and migration), they were used as a starting point for census taking. In order for the census to take advantage of household registrations, the registration data were reviewed and corrected. This both reduced the cost of taking the census and improved the quality of the registration data.

Migration, fertility, and state policy in Hubei Province, China

Despite China s one-child family planning policy, the nation experienced a slight rise in the birth rate in the mid-1980s. Many observers attributed this rise to the heightened fertility of those rural-to-urban migrants who moved without a change in registration (temporary migrants), presumably to avoid the surveillance of family planning programs at origin and destination. Using a sequential logit analysis with life-history data from a 1988 survey of Hubei Province, we test this possibility by comparing nonmigrants, permanent migrants, and temporary migrants. While changing family planning policies have a strong impact on timing of first birth and on the likelihood of higher-order births, migrants generally do not have more children than nonmigrants. In fact, migration tends to lower the propensity to have a child. More specifically, the fertility of temporary migrants does not differ significantly from that of other women.     

Temporary migration: a case study of Florida

Most migration statistics in the United States focus on changes in permanent residence, thereby missing temporary moves such as the daily commute to work, business trips, vacations, and seasonal migration. In this paper, we analyze temporary migration streams in Florida, focusing on moves that include an extended stay. Using several types of survey data, we examine the characteristics of non-Floridians who spend part of the year in Florida and Floridians who spend part of the year elsewhere. We develop estimates of the number, timing, and duration of temporary moves and the origins, destinations, characteristics, and motivations of temporary migrants. This study presents the most comprehensive analysis yet of temporary migration in Florida and provides a model that can be used in other places. It also points to a serious shortcoming in the US statistical system, namely, the lack of information on temporary migration streams. We believe the American Community Survey provides an opportunity to remedy this problem.     

Skilled temporary and permanent immigrants in the United States

The US temporary migration system is closely intertwined with the permanent system. First, this paper defines the various temporary and permanent admission categories. It presents available statistics on the occupations of temporary migrants upon admission and upon adjustment to permanent residency, especially since the Immigration Act of 1990 went into effect in 1992. There has been a sizable increase in the number of temporary workers over the past few years and those who adjust from specialty workers (H-1B) and intracompany transferee (L) have increased the overall skill composition of permanent immigrants. Secondly, the paper reviews the literature on the labor market impact of temporary migrants in academics and in the private sector. While there are marked concentrations of foreign-born workers among the college educated and especially Ph.D.s, the literature raises concerns but does not establish adverse effects (wage differentials, unemployment, etc.). There is, however, reason for some concern given trends in the postdoctoral labor market and for employersin `job shops' who undercut US workers with temporary workers.

Does it Take a Village? Migration among Rural South African Youth

In a rural African context, the saying, “it takes a village to raise a child,” suggests that community characteristics are substantially important in children’s lives as they transit to adulthood. Are these contextual factors also related to youth migration? Demographers are uncertain about how community characteristics improve our understanding of an individual’s propensity to migrate, beyond individual and household factors. In many low- and middle-income country settings, youth become migrants for the first time in their lives to provide access to resources that their families need. We employ discrete-time event history models from 2003 to 2011 Agincourt Health and socio-Demographic Surveillance System in rural South Africa to test whether markers of development in a village are associated with the likelihood of youth and young adults migrating, distinguishing between becoming temporary and permanent migrants during this critical life cycle phase. We find that village characteristics indeed differentially predict migration, but not nearly as substantially as might be expected.     

The effects of climate change on the geography and timing of human mobility

Human mobility over different distances and time scales has long been associated with environmental change, and the idea of climate change is now affecting movement in new ways. In this paper, we discuss three cases from the South Pacific to explain the ways anticipated climate futures are changing mobility in the present. First, we examine village relocation in response to coastal erosion and inundation in Fiji, drawing on our study of the unfolding experience of Narikoso village in Kadavu Province. In contrast to this spatially constrained process of permanent relocation, we examine the spatially extended yet temporally constrained seasonal migrant worker programme that aims to support economic development in the Pacific Islands by providing temporary work visas in Australia and New Zealand. Finally, we examine the likely effects of proposed open labour markets as a means to promote climate change adaptation, through a study of the analogous example of Niuean migration to New Zealand which has resulted in both permanent migration and a slow circulation of people between both countries. Across these examples, we highlight emerging and potentially constructive ways in which climate change is altering the spatio-temporal patterns and rhythms of mobility.     

The Impact of Migration on Fertility under China’s Underlying Restrictions: A Comparative Study Between Permanent and Temporary Migrants

Compared with that in other countries, the issue of fertility in China is more complicated because of its restriction policy or system. Several major hypotheses have been proposed to explain and predict the impact of migration on China’s fertility regardless of China’s real situation. Therefore, this paper analyzes the impact of migration on fertility considering China’s underlying restrictions using the data from the Chinese General Social Survey carried out in 2008. The social class in this study was divided into two, namely urban class and rural class. By building the 2 × 2 mobility tables and the diagonal mobility model, the study determined the impact of migration on fertility and analyzed the influence of some restrictions, such as family planning, traditional fertility concept, and household registration system. Results show that migration greatly affects fertility: upward migration (i.e., from rural to urban) may decrease the fertility, whereas downward migration (i.e., from urban to rural) may increase it. The degree of decline on fertility is greater than that of increase. Family planning still plays a role in fertility decline. Traditional concepts on fertility, for example, bringing up sons to take care of parents in their old age and preferring boys to girls, are anchored on the people’s mind, which is detrimental to the stability of the fertility rate. Moreover, the household registration system primarily influences the fertility behavior of temporary migration, with a negative relationship between them.     

Earnings adjustment of temporary migrants

The strong incentives of migrants to invest into human capital and the positive selective character of migration are the main explanations for the rapid decrease of the earnings gap between migrants and natives, and, in some cases, the cross-over of migrants' earings profiles with those of native workers, as found in a variety of empirical studies on migration to the USA, Canada and Australia. The present paper shows that in the case of temporary migration the optimal investment into country specific human capital should be lower than in the case of permanent migration. Investments may not be sufficient to allow migrants' earnings to catch up with those of native workers. Furthermore, it is shown that migration is positively selective only under certain labor market conditions. Empirical findings support the hypothesis that the migrant's length of stay in the host country has an effect on his investment into human capital and, consequently, on his earnings position. The results strongly suggest the need for carefully differentiating between temporary and permanent migration when investigating migrants' learnings assimilation.I am grateful to Augustin Maravall, John Micklewright, Graham Mizon, Christoph M.

Family Migration Pattern in China

Do an increase in ageing in developed countries and ＂getting old before getting rich＂ in developing countries indicate that fluctuations 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 retirement age and Long-term stability in a sustainable system,Gradually raising the replacement fertility is the key to solving the socioeconomic development dilemma presented by future population ageing in low fertility regions or cotlntries,but the latter is more urgent.     

Environmental security and labor migration in Nepal

Do changes in environmental security that result from declining access to forest resources shape labor migration in a context where household production and consumption are intimately dependent on natural resources? Using 1996 household data from the Chitwan Valley of Nepal, we examined if a decrease in access to firewood increased the likelihood of migration of individuals for work. The results of multinomial logistic regression showed that, environmental insecurity was a significant predictor for migration regardless of destination, domestic or international. Labor requirements for household maintenance also played an important role in the decision to migrate. Management of forest resources and poverty alleviation by providing firewood substitutes and economic opportunities at the local level is likely to change the labor migration flow, which could be an important issue for future research.     

中国超大城市常住外来和常住户籍人口居住－就业的空间错位--基于北京、上海和广州的实证

以北京、上海、广州作为中国超大城市的代表,探讨中国超大城市常住外来和常住户籍人口居住－就业空间错位的差异及其影响因素。总体而言,常住外来人口的居住－就业空间错位要高于常住户籍人口,且不同户籍属性人口的错位形态存在差异。分行业来看,公共管理和社会组织等公共服务业常住外来人口居住－就业空间错位程度相对较高,而制造业、居民服务和其他服务业常住户籍人口居住－就业空间错位程度相对较高。由计量分析发现,住房价格水平、就业集聚规模、高端产业比重和地区地方财政支出对不同户籍属性人口就业－居住空间分布差异均产生相似的影响;而租赁户数比重和低端产业比重对不同户籍属性人口的就业－居住空间分布则产生差异性的影响。     

Globalization and changes in Australian international migration

Australian international migration has undergone a massive transformation in the last decade, in part as a result of globalization. Although Australia has long been a country of immigration with a relatively high proportion of its residents foreign-born, the nature of international migration shaping the country has undergone profound change in the era of globalization. This paper outlines some of the major dimensions of this change in international migration. The links between globalization and migration are complex and two-way but there can be no doubt that processes which have accelerated international exchanges of goods, information, ideas, trade and finance and led to an internationalization of labour markets have been associated with shifts in Australian migration. This change has had a number of components which have increased the complexity of the international migration influencing Australia. The changes examined include the increasing significance of skill-related migration compared with other forms, increasing non-permanent migration, the increasing nexus between temporary and permanent migration, the increasing movement of Australians out of the country, the significance of student migration and the increasing significance of migration in influencing Australia’s relationship with its Asia-Pacific neighbours. These changes have profound implications for Australia’s contemporary and future demography.     

Climate change and internal migration intentions in the forest-savannah transition zone of Ghana

Migration is at the centre of demographic research on the population–environment nexus. Increasing concerns about the impacts of environmental events on human population are fuelling interest on the relationship between migration and environmental change. Using data from the Climate Change Collective Learning and Observatory Network Ghana project, we employ binary logistic regression to examine migration intentions of households in response to major community stressors including climate-related ones. The results indicate that the type of community stressor that affects households most does not differentiate migration intentions in Ghana’s forest-savannah transition zone: Even though the majority of the respondents mentioned climate-related events as the stressor that affects them the most, such events do not appear to directly explain migration intentions. However, socio-demographic factors such as age, household size and current migration status are significant predictors of migration intentions, with younger household heads, heads of migrant households and heads of smaller households being relatively more likely to have migration intentions than other household heads. We conclude that migration drivers are multifaceted and deserve further research because even in areas with perceived environmental stress, climate-related events may not be the primary motivation for migration intentions.
