Family Migration in a Developing Country

A family model of migration is developed and empirically tested by using longitudinal data for respondents living in Ilocos Norte Province, Philippines. Based on the framework of a family-migration system, family migration is assumed to depend on the character of linkage to the migration system, family household structure, socio-economic resources, family pressure to migrate, family/kin ties to place of origin, and previous mobility experience of family members. Family-migration behaviour is specified as migration of some (one or more) family members, or of the entire family. The findings support the importance of linkage to a family-migration system by way of remittances and the previous mobility experience of family members in the prediction of both types of family migration. Migration of some family members is also predicted by fewer parcels of land owned, higher levels of education, larger household size, and an early life-course stage. Family pressure to migrate, indicating the interactional context of the family, is important for the migration of entire families. It is concluded that the framework used and results presented help explain how migration becomes an institutionalized reality of family life in many developing countries.     

Work disability and migration in the early years of welfare reform

The inter- and intra-state migration of American families with work-disabled members is a neglected area of empirical study. Longitudinal migration and health status data from the 1996 Panel of the Survey of Income and Program Participation (SIPP) are merged with state-level welfare policy indicators to investigate migration behavior under welfare reform’s emphasis on requiring work and encouraging reliance on social support networks. We use a nested discrete-choice event history model that incorporates the departure decision and interstate destination choice in a single model that tests the effects of state-level welfare policy and economic opportunity characteristics, with state fixed effects, plus family sociodemographic characteristics and social networks, as the basis for comparing migration of families with and without work disabilities. The results show that although families with disabilities and illnesses are less likely to migrate than other families generally, they are “pushed” to migrate if they live in states that do not exempt them from TANF activities requirements. Furthermore, in-migration is inhibited by stringent state welfare illness exemption rules and high state unemployment rates. Intrastate migration is more likely among families who received family and community social support, regardless of work-disability status.     

Labour migration as a response to relative deprivation

In this paper we define the relative deprivation of a person with income y as an increasing function of the percentage of individuals in the person's reference group whose income is larger than y. We obtain his satisfaction by adding up the marginal utilities of income over the range of income a person possesses. We model migration from one reference group to another as a response to relative deprivation and satisfaction: We say that a strong incentive to migrate exists if relative deprivation decreases while satisfaction rises with migration and that a weak incentive exists if the individual increases or decreases his satisfaction and deprivation at the same time by migrating. We derive conditions under which different incentives, weak or strong, hold for different individuals. We obtain the result that in general the richest individual in a society will not have a strong incentive to migrate but may have a weak incentive to migrate, whereas the poorest individual may have a strong incentive to migrate and also a weak incentive to migrate. Our analysis enables us to explain several perplexing migratory phenomena, identify income inequality as a distinct explanatory variable of migration and establish an incentive to migrate in situations where the utility-social welfare approach does not.This is a revised version of Harvard University Migration and Development Program, Discussion Paper No. 20. We are indebted to an anonymous referee for helpful comments and suggestions.     

The impact of changes in the marital status on return migration of family migrants

Many migrants have non-labour motives to migrate, and they differ substantially from labour migrants in their migration behaviour. For family migrants, the decision to return is highly influenced by changes in their marital status. Using administrative panel data on the entire population of recent family immigrants to the Netherlands, we estimate the effect of a divorce and remarriage on the hazard of leaving the Netherlands using a ‘timing of events’ model. The model allows for correlated unobserved heterogeneity across the migration, the divorce and remarriage processes. The family migrants are divided into five groups based on the Human Development Index (HDI) of their country of birth. We find that both divorce and remarriage increase return of family migrants from less-developed countries. Remarriage of family migrants from developed countries makes them more prone to stay. Young migrants are influenced most by a divorce. The impact of the timing of a divorce and remarriage on return is quantified graphically.     

The Relationship Between Resources and Human Migration Patterns in Central Kamchatka During the Post-Soviet Period

This paper examines the relationship between resources and migration in post-Soviet Kamchatka (Russian Far East). During the post-Soviet period of socio-economic hardship, migration trends have changed drastically both in central Kamchatka and throughout the Russian Far East. I predicted that there would be a clear relationship between resource scarcity and people's decisions to leave in search of more propitious opportunities. Against the backdrop of economic decline, out-migration prevailed in central Kamchatka throughout the post-Soviet period; however, migration patterns among villages in this rural and resource-dependent region diverge considerably. Villages in central Kamchatka facing a local natural resource crisis show greater net negative migration than those with a relatively intact resource base. Such variation is notable, given the relatively contained area of the study; it suggests migration patterns are closely tied to ecological conditions. Besides socio-economic and ecological factors, historical circumstances also influence migration patterns. The decision to migrate is complex, arising from the interaction of socio-economic, political, ecological, and historical conditions.     

Vertical mobility and community type as factors in the migration of college graduates

Internal migration statistics are generally inadequate. One of the chief sources of this is the lack of direct data relating to migration. There appears also to be a lack of interest on the part of researchers in pursuing the study of the relationship between vertical mobility and migration. This study is designed to determine the relative importance of intergenerational vertical mobility and type of community or place of origin in contributing to the migration of college graduates by using direct mobility and migration data.The study sample consists of 850 employed male graduates of eight private colleges in Iowa between 1954 and 1958. Data were obtained through the colleges and consist, among other things, of information about fathers' occupations, graduates' occupations, and the addresses of graduates both at matriculation and at the time of the study. Information about communities or places of origin is dichotomized on the basis of whether they are located in Standard Metropolitan Areas (SMA's) in 1950 or whether they are located in non-SMA's (NSMA's). Upward mobility is treated as a product of higher education and as an antecedent of migration.Hypotheses asserting the existence of associations between mobility and migration and between type of community or place of origin and migration are tested. Associations are established showing (1) that upwardly mobile graduates are more likely to migrate than others and (2) that graduates from NSMA's are more likely to migrate than graduates from SMA's.The relative influence of the two factors is determined by partialing the associations between each factor and migration while holding the other factor constant. Type of community or place of origin is found to be of greater importance for migration than is upward mobility. Graduates from NSMA's are more likely to migrate than those from SMA's, regardless of their relative mobility. Graduates from SMA's are likely to migrate only if they are also upwardly mobile.     

Social status inconsistency and migration

We use NLSY79 panel data to extend the line of sociological research encouraged in the early work of Lenski by analyzing the effects of social status inconsistencies on the likelihood and direction of migration. Given that migration is often viewed as a way for individuals to locate prospective returns fitting for their qualifications, analysis of migration behavior offers an opportunity to examine the impact of status inconsistency. Key findings indicate that under-rewarded individuals, specifically relatively highly educated individuals in low status and low paying occupations, are more likely to migrate than are status consistent individuals. Over-rewarded individuals are less likely to migrate. These findings vary across metropolitan and nonmetropolitan places: individuals in nonmetropolitan areas who are under-rewarded or have mixed statuses have higher odds of migration than status consistent respondents. Individuals in metropolitan areas with inconsistent statuses are not more likely to migrate than status consistent respondents once other determinants of migration are entered in the analysis. Exploratory analysis shows migration increases the likelihood of achieving status consistency. Further examination of the interrelationship between migration and status inconsistency is recommended.     

Different Reasons,Different Results: Implications of Migration by Gender and Family Status

Previous research on migration and gendered career outcomes centers on couples and rarely examines the reason for the move. The implicit assumption is usually that households migrate in response to job opportunities. Based on a two-year panel from the Current Population Survey, this article uses stated reasons for geographic mobility to compare earnings outcomes among job migrants, family migrants, and quality-of-life migrants by gender and family status. We further assess the impact of migration on couples’ internal household economy. The effects of job-related moves that we find are reduced substantially in the fixed-effects models, indicating strong selection effects. Married women who moved for family reasons experience significant and substantial earnings declines. Consistent with conventional models of migration, we find that household earnings and income and gender specialization increase following job migration. Married women who are secondary earners have increased odds of reducing their labor supply following migration for job or family reasons. However, we also find that migrating women who contributed as equals to the household economy before the move are no more likely than nonmigrant women to exit work or to work part-time. Equal breadwinner status may protect women from becoming tied movers.     

A Panel Based Analysis of the Effects of Race/Ethnicity and Other Individual Level Characteristics at Leaving on Returning

Individual level differentials between migrants and nonmigrants are examined to ascertain the likelihood of return migration to a prior residence based on characteristics at the time of departure from place of origin. Analysis focuses on comparisons of Hispanics, blacks and whites, examining the odds of return migration by education, employment status, marital status, home ownership, length of residence, gender, age, and migration interval. The 1979 National Longitudinal Survey of Youth (NLSY79) is utilized to identify 13,798 preliminary migrations that may be followed by at least one return migration. Findings indicate a sharp decline in propensity to return migrate as length of absence from origin increases. Regardless of length of time since the preliminary migration, both blacks and Hispanics are more likely to return migrate than are whites. Individuals who resided at place of origin for longer periods before leaving had strikingly higher odds for return migration.

Effects of Parents' Migration on the Education of Children Left Behind in Rural China

This essay draws on an original cross‐sectional survey of 1,010 children and their guardians in highly migratory regions of Anhui and Jiangxi provinces located in China's interior. It uses propensity score matching, a technique that mitigates endogenity, to examine the impact of parental migration and post‐migration guardianship arrangements on the children's educational performance as measured by test scores for Chinese and mathematics. One core finding is that the educational performance of children is adversely affected by parental migration only when both parents migrate or when a non‐parent guardian is the principal carer. Additionally, longer durations of parental absence are associated with poorer educational performance. The migration of two parents only significantly adversely affects the educational performance of boys. There is no significant effect on the educational performance of girls. On the basis of our findings we argue that rather than support left‐behind children within the countryside, the long‐term policy response should be to remove the institutional obstacles that prevent family resettlement in the cities.     

Elderly migration: For sun and money

Discussions about elderly migration and its implications for growth planning tend to neglect the role of economic forces. Our view is that cost-of-living variations among states give elderly households on fixed incomes an incentive to move that closely resembles the effects of wage opportunities on workers who migrate. To test this view, we employ a state-by-state index of cost of living for a retired couple to explore its impact on migration choices of the elderly. The effects of cost of living on migration are investigated in terms of the probability that an elderly person will move out-of-state during a five-year period and the probability that a given state will be chosen as destination once a decision has been made to migrate. The influences of cost of living at both origin and destination are strongly confirmed.

Youth Migration Decisions in Sub-Saharan Africa: Satellite-Based Empirical Evidence from Nigeria

This article examines the implications of urban growth on youth migration decisions in Nigeria. We use night light intensity data combined with Living Standards Measurement Study-Integrated Surveys on Agriculture data, as an indicator of urban growth and associated economic opportunities. Employing alternative econometric approaches that exploit the spatial and temporal differences in urban growth as proxied by night light intensity, we find that urban growth in potential migrant destinations encourages youth migration. We also find heterogeneous responses to urban growth among various groups of youth as well as varying responses to different types of migration. Broadly, women and those youth with more education are more likely to migrate, while those in households with livestock are less likely to migrate. Often, however, the effects are complex and varied. For example, land and physical asset ownership encourage temporary migration; but greater land ownership discourages permanent migration, while physical assets have insignificant effects. Our results from Nigeria show that policy makers concerned about rural–urban youth exodus should adopt a differentiated, in terms of targets, and multidimensional policy approach to reap the benefits of urbanization while avoiding its negative consequences.     

Self-selection in migration and returns to unobservables

We build a model of migration that considers both observable and unobservable individual characteristics and their returns across locations. We focus on the interprovincial migration patterns of Canadian physicians, in part, because physicians are paid on a fee-for-service basis. Because fees are exogenous, we can estimate a mixed conditional-logit model to determine the effects of individual- and destination-specific characteristics (particularly earnings differentials) on physician location decisions. We find, among other things, that individuals with greater earnings potential based on unobservables are more likely to migrate to provinces where the returns to such unobservables are greater.      

Fertility adaptation of rural-to-urban migrant women: A method of estimation applled to Korean women

This study proposes to test for the existence of an adaptation effect of rural-to-urban migration. The design is to divide migrants into two groups at the time of observation: one group which had migrated by that time, and another group consisting of individuals who had not yet migrated but are known to migrate later. It is presumed that if the former group had not migrated it would have had a birth path similar to the latter group. Adaptation is measured by the difference between this hypothetical birth path and the actual birth path of migrants observed after they migrate. The model is tested on Korean women and found to support the existence of an adaptation effect.     

Who moves and who stays? Rural out-migration in Nigeria

Data from the nationally representative 1993 Migration and Urbanization Survey of Nigeria are used to simultaneously examine the patterns of rural-rural and rural-urban migration in Nigeria. A multinomial logistic regression model predicts the independent and collective association between individual, household, and regional variables and migration from rural areas to rural and urban destinations. Associations between education, religion and ethnicity and migration propensities exist at the national level. The Kanuri-Shua Arabs are generally non-migrants, the Hausa-Fulani and Yoruba are predominantly rural-rural migrants and the Igbo-Ibibio and Urhobo-Isoko-Edo are predominantly ruralurban migrants. Christians are significantly more mobile than Muslims. While the highly educated are most likely to choose an urban destination, a significant proportion migrate to other rural areas. Concern over population concentration is not supported, as rural migrants move to all regions and to urban and rural areas.     

Migration decision making and migration behavior in rural Kenya

Micro theories of migration have generally been tested with data which do not allow one to distinguish between the decision to move and the act of moving. The latter is usually treated as a proxy for the former. Using data from a two round survey of youth in rural Kenya we classify respondents as decision processors/nondecision processors from round one data, and determine who migrates over a nine month interval from round two data. Thirty-four percent of the sample are classified as decision processors and 25% as migrants, but decision processors were only slightly more likely to migrate than nondecision processors and more migrants actually came from the latter group.A simple model is developed to determine the extent to which the same factors that influence decision-processing influence who migrates. The model is tested using regression procedures by first treating decision-processing as the dependent variable then migration. The model explains 26% of the variance in who decides, but only 10% of the variance in who actually moved. Finally, separate analyses are done of the determinants of migration for decision processors and nondecision processors.     

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。
