Linkages between internal and international migration: the Ilocos Norte experience

This paper reviews the arguments concerning whether internal and international migration can or should be incorporated in the same migration theories or models and examines the ways in which the 2 processes are linked in a variety of contexts. To provide some illustrative empirical results, reference is made to the Philippine Migration Study (PMS), a research project which incorporates both internal and international migration in its research design. The study examined migration from Ilocos Norte to the principal internal destination, Manila, and the principal international destination, Honolulu. Ilocos Norte is a largely rural, resource poor province with a long history of outmigration that is attributable primarily to population pressure in the region. Due to the fact that 1 of the principal migration streams from the Ilocos is within the Philippines and the other is outside the country, the Ilocos presents an ideal situation for a comparative analysis of internal and international migration. The study consists of 7 different surveys conducted in Ilocos Norte, Manila, and Honolulu between 1980-83. More than 5000 interviews were conducted in the 3 locations. The initial baseline survey in Ilocos Norte was conducted in 1980. After 2-1/2 years, the initial 830 households in the Ilocos Baseline Survey were recontacted to determine the migration behavior of the household members since the 1st survey. Those who had moved to either Manila or Hawaii during this period were traced to the destination and interviewed there. The PMS uses a single integrated model (the value-expectancy or VE framework) to explore migration decision making for both internal and external migration. Despite the complexity of the VE questions, respondents were able to distinguish different locations as being relatively good places or bad places to realize their different goals. Manila was not highly regarded by Ilocanos in most respects, and there was not a single value on which Manila ranked higher than both alternative locations. Relative to the other values, however, Manila is seen as being a good place for educational opportunities and entertainment. Hawaii rated very well on items having to do with wealth and status, but was regarded as a relatively poor place to satisfy one's desire for affiliation. Comfort, affiliation, and morality were viewed as being most easily achieved in the present barangay. Based upon the value-expectancy framework, the findings of the Philippine Migration Study confirm that a global model of migration decision making is feasible and that other important concepts in migration equally apply well in the case of both internal and international population movements.     

Interrelations between migration and fertility in Thailand

Based on special tabulations of 1960 census data on migration within Thailand, this analysis attempts to assess the role of migration in the urbanization process and the relation between migration and fertility. The importance of migration to urban growth is evidenced by the clearcut positive relationship between the percentage of persons classified as either lifetime or 5-year migrants and the urban character of their 1960 place of residence. Yet, the evidence also points to an increasing proportion of urban growth in recent decades attributable to natural increase. The specific relation between fertility and migration varies depending on the measure of migration used: Compared to nonmigrants in their place of destination, the fertility levels of lifetime migrants are not very different; but those of 5-year migrants are considerably lower. Regardless of migration status, however, fertility level is markedly lower for those living in urban places compared to those in rural places. This suggests the important role of both migration and urbanization in affecting fertility levels in Thailand.     

Migrant fertility in Ghana: selection versus adaptation and disruption as causal mechanisms

The aim of the study presented in this paper is to disentangle the roles of three mechanisms -- selection, adaptation, and disruption -- in influencing migrant fertility in Ghana. Using data from the 1998 Ghana Demographic and Health Survey, we fit Poisson and sequential logit regression models to discern the effects of the above mechanisms on cumulative fertility and annual probabilities of birth. Characteristics of migrants from four types of migration stream are examined and compared with those of non-migrants at origin and destination. We find substantial support for the selection hypothesis among both rural-urban and urban-rural migrants. Disruption is evident only in the fertility timing of second and higher-order births in Ghana. Our finding that migrants bear children at about the same rates as the natives at destination implies that the growth rate of cities will slow down quickly and that the rural population will continue to have high fertility. Thus to achieve a reduction in the national fertility level, family planning activities need to be directed towards rural areas.     

Location of adult children as an attraction for black and white elderly return and onward migrants in the United States: Application of a three-level nested logit model with census data

This article assesses the influence of the location of adult children on the 1985-90 interstate migration of black and white elderly "nonnatives" (i.e., those whose state of residence in 1985 was different from their state of birth) in the United States, based on the application of a three-level nested logit model with 1990 census data. The model accounts for (1) the choice between departing and staying put, (2) the choice between return and onward migration, and (3) the choice of a specific destination. The main findings are as follows. First, elderly nonnatives were strongly attracted by the location of their adult children when they made their migration decisions at all levels of the choice framework, and this attraction was stronger for the widowed than for those of other marital statuses. This finding can be taken as empirical support for Eugene Litwak's theory of the modified extended family. Second, in the return/onward and destination choice processes, the attraction of the location of adult children was found to be stronger for whites than for blacks. This finding is consistent with the finding of Hogan et al. (1993) that whites had stronger inter-generational connections than did blacks.     

The Process of Familization of Migration in China

China is a transitional and developing country with the largest population and number of farmers in the world, and shows a striking feature of urban-rural dual structure. The major content in China＇s rising modernization is the process of urbanization transformation, urbanization of small and middle-sized city in China should become the basic path selection. Which involves three important issues： concept, people, and institution. Only based on the modernization of concept, people and institution, there will automatically generate the modernization of industry, agriculture, technology and national defense, and thus consistently developing prosperous of both the country and the citizens.     

Health Selection,Migration, and HIV Infection in Malawi

Despite its importance in studies of migrant health, selectivity of migrants—also known as migration health selection—has seldom been examined in sub-Saharan Africa (SSA). This neglect is problematic because several features of the context in which migration occurs in SSA—very high levels of HIV, in particular—differ from contextual features in regions that have been studied more thoroughly. To address this important gap, we use longitudinal panel data from Malawi to examine whether migrants differ from nonmigrants in pre-migration health, assessed via SF-12 measures of mental and physical health. In addition to overall health selection, we focus on three more-specific factors that may affect the relationship between migration and health: (1) whether migration health selection differs by destination (rural-rural, rural-town, and rural-urban), (2) whether HIV infection moderates the relationship between migration and health, and (3) whether circular migrants differ in pre-migration health status. We find evidence of the healthy migrant phenomenon in Malawi, where physically healthier individuals are more likely to move. This relationship varies by migration destination, with healthier rural migrants moving to urban and other rural areas. We also find interactions between HIV-infected status and health: HIV-infected women moving to cities are physically healthier than their nonmigrant counterparts.     

Explaining hierarchical and interprovincial migrations of Chinese young adults by personal factors and place attributes: a nested logit analysis

"This paper uses a two-level nested logit model to explain the inter-stratum (city, town and rural county) and interprovincial migration behaviors of the young adults (aged 17-29) in China during a three-year period (1985-87), based on the micro data of the 1987 National Population Survey. The migration propensity of each person is represented by a departure probability and a destination choice probability. These probabilities are then expressed as functions of personal factors and place attributes. The main findings are that personal factors are of paramount importance in explaining the departure behaviors, and that both departure and destination behaviors responded to market forces in a sensible way, despite government control on territorial movements."     

Fertility adaptation by rural-urban migrants in developing countries: The case of Korea

Summary The purpose of this study is to develop and test a model to assess the influence of rural-urban migration on fertility in less developed countries. Two major reasons may account for lower fertility levels observed among such migrants than among women who remained in rural areas: a selection effect, and adaptation to constraints in the area of destination. Results of previous studies have only rarely suggested that the effect of adaptation was significant. We use the detailed personal migration and pregnancy histories recorded in the Korean World Fertility Survey of 1974 and an autoregressive model to control for unobservable variations in personal preferences for different family sizes between migrants and non-migrants. Our study provides evidence that adaptation following rural-urban migration is a significant factor which explains the lower fertility of rural-urban migrants compared with that of rural stayers.     

From Europe to the Americas: a comparative panel-data analysis of migration to Argentina, Brazil, and the United States, 1870–1910

We use annual panel data, 1870–1910, to estimate and compare the determinants of European emigration to Argentina, Brazil, and the USA. The Hausman–Taylor instrumental variable technique we use provides for cross-sectional (country) controls, accounts for variables that are potentially correlated with the unobservables and allows the recovery of the coefficients of temporally invariant variables. In general, migration was from low-wage source countries, from countries with large stocks of immigrants in the destination who were born in the origin, and from countries with relatively much recent migration to the destination. Certain determinants differ considerably for the three countries.     

Exploring Child Mortality Risks Associated with Diverse Patterns of Maternal Migration in Haiti

Internal migration is a salient dimension of adulthood in Haiti, particularly among women. Despite the high prevalence of migration in Haiti, it remains unknown whether Haitian women’s diverse patterns of migration influence their children’s health and survival. In this paper, we introduce the concept of lateral (i.e., rural-to-rural, urban-to-urban) versus nonlateral (i.e., rural-to-urban, urban-to-rural) migration to describe how some patterns of mothers’ internal migration may be associated with particularly high mortality among children. We use the 2006 Haitian Demographic and Health Survey to estimate a series of discrete-time hazard models among 7,409 rural children and 3,864 urban children. We find that compared with their peers with nonmigrant mothers, children born to lateral migrants generally experience lower mortality, whereas those born to nonlateral migrants generally experience higher mortality. Although there are important distinctions across Haiti’s rural and urban contexts, these associations remain net of socioeconomic factors, suggesting they are not entirely attributable to migrant selection. Considering the timing of maternal migration uncovers even more variation in the child health implications of maternal migration; however, the results counter the standard disruption and adaptation perspective. Although future work is needed to identify the processes underlying the differential risk of child mortality across lateral versus nonlateral migrants, the study demonstrates that looking beyond rural-to-urban migration and considering the timing of maternal migration can provide a fuller, more complex understanding of migration’s association with child health.     

A Profile of the World's Young Developing Country International Migrants

Individual‐level census and household survey data are used to present a rich profile of young developing country international migrants around the world. They are found to comprise a large share of the flow of migrants, particularly among migrants to other developing countries, with the age distribution of migrants peaking in the late teens or early twenties. Detailed data are presented on the age and sex composition of migrants, on whether young migrants move alone or with a parent or spouse, on their participation in schooling and work in the destination country, on the types of jobs they have, and on the incidence and age of return migration. The results suggest a high degree of commonality in the youth immigrant experience across a number of destination countries. Recent developing country young migrants tend to work in similar occupations and are more concentrated in these occupations than recent older migrants or young immigrants who arrived at an earlier age. Nevertheless, there is also considerable heterogeneity among young immigrants with respect to school attendance and work in their destination country. The potential of international migration for building human capital is significant but far from being fully used.     

Race,gender, and marriage: destination selection during the great migration

Using historical census microdata, we present a unique analysis of racial and gender disparities in destination selection and an exploration of hypotheses regarding tied migration in the historical context of the Great Migration. Black migrants were more likely to move to metropolitan areas and central cities throughout the period, while white migrants were more likely to locate in nonmetropolitan and farm destinations. Gender differences were largely dependent on marital status. Consistent with the "tied-migration" thesis, married women had destination outcomes that were similar to those of men, whereas single women had a greater propensity to reside in metropolitan locations where economic opportunities for women were more plentiful.     

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.     

Metropolitan migration efficiency

The migration efficiency ratio of an area is defined as the net migration of the area (in-migrants minus out-migrants) divided by the total number of moves whose origin or destination is that area (in-migrants plus out-migrants) multiplied by 100. This paper investigates variations in migration efficiency from 1955 to 1960 among Standard Metropolitan Statistical Areas with populations of 250,000 or more. Regional variation in migration efficiency was evident, ranging from an average of ?9.7 in the Northeast to 19.6 for SMSA’s in the Western region. Nonwhites tended to have higher migration efficiency than whites. Rapidly growing metropolitan areas had higher migration efficiency ratios than areas growing at a lower rate or losing population. The educational level of a metropolitan area, as measured by the percent of the population 25 years old or over with at least a high school education, was positively related to migration efficiency. The composition of the migrant population, both in- and outmigrants for a given area, was related to the value of the migration efficiency ratio. If the migrant population contained a large proportion of persons aged 20–34, migration efficiency was low, regardless of the direction of the major migration stream. Region was found to have a major effect. Variables that had a strong and positive relationship with migration efficiency in one region were usually found to have no relation, or a negative relation, with it in other areas. Obviously, further research is needed for the identification of factors producing these strong regional effects.     

Commoditization of Lifestyle Migration: Japanese Retirees in Malaysia

Abstract

This paper aims to explore the relationship between mobilities created from individual choices and the market factors driving lifestyle migration. The transnational mobility of elderly Japanese throughout Asia is considered one of the emerging cases of international retirement migration in Asia, an overall relatively new phenomenon. Through examining the sociocultural aspects of lifestyle migration in the case of Japanese international retirement migration to Malaysia, this paper argues that lifestyle migration, as a form of consumption, results in self-realization that has a culturally specific meaning for Japanese retirees. By linking tourism and migration, this paper proposes that the mobilities market serves as a mediator of transnational human mobilities and argues that the commoditization of Japanese international retirement migration reflects on both the socioeconomic and sociocultural aspects of Japan as an aging society. Ethnographic data, alongside media discourse analysis, demonstrates how the expectation of self-realization is mediated through the promotion of Malaysia as a destination country of Japanese international retirement migration and their culturally specific understandings of retirement lifestyle.     

Will They Stay? Foreign-Born Out-Migration from New U.S. Destinations

Immigrants living in new destinations in 1995 were 2.5 times more likely to have migrated to another labor market by 2000 as immigrants living in traditional places. The researchers look at two competing explanations for immigrants’ differential internal migration patterns, namely that immigrants prefer areas with relatively large nativity concentrations which provide them with social support versus immigrants are target earners who prefer robust labor markets with strong employment growth and high wages. Utilizing confidential Census data for 1990 and 2000, the authors develop new destination classifications for 741 labor markets that take into account the differential growth and composition characteristics of 24 Asian, Latin American and Caribbean immigrant groups living in those markets. The empirical analysis of labor market out-migration indicates that immigrants do not see internal migration as an either/or choice between economics and social support but prefer residence places that allow them to maximize both conditions.

Migration,Marital Change,and HIV Infection in Malawi

Research on the relationship between migration and HIV infection in sub-Saharan Africa often suggests that migrants are at higher risk of HIV infection because they are more likely to engage in HIV risk behaviors than nonmigrants, and they tend to move to areas with a relatively higher HIV prevalence. Although migration may be a risk factor for HIV infection, I instead focus on the possibility that the HIV positive are more likely to migrate. Using a longitudinal data set of permanent rural residents and migrants from Malawi, I find that migrants originating from rural areas are indeed more likely than nonmigrants to be HIV positive and to have engaged in HIV risk behaviors. The increased HIV risk among migrants may be due to the selection of HIV-positive individuals into migration; I find that HIV-positive individuals are more likely to migrate than those who are HIV negative. The explanation for this phenomenon appears to be marital instability, which occurs more frequently among HIV-positive individuals and leads to migration after marital change.     

Migration Selection, Protection, and Acculturation in Health: A Binational Perspective on Older Adults

In this article, we test for four potential explanations of the Hispanic Health Paradox (HHP): the “salmon bias,” emigration selection, and sociocultural protection originating in either destination or sending country. To reduce biases related to attrition by return migration typical of most U.S.-based surveys, we combine data from the Mexican Health and Aging Study in Mexico and the U.S. National Health Interview Survey to compare self-reported diabetes, hypertension, current smoking, obesity, and self-rated health among Mexican-born men ages 50 and older according to their previous U.S. migration experience, and U.S.-born Mexican Americans and non-Hispanic whites. We also use height, a measure of health during childhood, to bolster some of our tests. We find an immigrant advantage relative to non-Hispanic whites in hypertension and, to a lesser extent, obesity. We find evidence consistent with emigration selection and the salmon bias in height, hypertension, and self-rated health among immigrants with less than 15 years of experience in the United States; we do not find conclusive evidence consistent with sociocultural protection mechanisms. Finally, we illustrate that although ignoring return migrants when testing for the HHP and its mechanisms, as well as for the association between U.S. experience and health, exaggerates these associations, they are not fully driven by return migration-related attrition.     

Descriptive Analysis of the Individual Migratory Pathways According to Environmental Typologies

This study tests the influence of environmental changes on migration in Burkina Faso. It describes individual migratory pathways in the 1960–1999 period in Burkina Faso, using environmental typologies of origins and destinations based on rainfall variations and land degradation. The study links data from a national longitudinal (retrospective) survey with fine resolution rainfall data and land degradation data. Results suggest that environmental factors influence, but in different ways, both the probability to out-migrate and the selection of a destination once the migration decision has been made. Migration seems to be more influenced by a slow-acting process such as land degradation than by episodic events such as droughts.
