Migration and fertility in the Philippines: Hendershot's selectivity model revisited

A demographer compared 1983 data on 5092 currently married migrant and nonmigrant women living in the Philippines to determine whether migration was still selective in terms of fertility behavior or not. Fertility was basically the same between migrant and nonmigrant women in their early reproductive years, but clear differences existed between older migrants and nonmigrants as indicated by children ever born (CEB). In fact, migration did not significantly affect cumulative fertility at all (correlation ratio=.03). Moreover its effect was further reduced when the researchers controlled for age and duration of marriage. Besides level of education and contraceptive use status contributed more to explanations of fertility differentials (correlation ratio=.09 for both) than did migration. The mean number of CEB adjusted for all variables fell with level of education from 4.18 for those with primary education to 3.63 to those with college education. This result identified education as a means to reduce high fertility in the Philippines. On the other hand, the mean was higher among women who ever used contraception than it was for those who never used it (4.21 vs. 3.72). Apparently considerable family size motivated mothers to use contraception. Since women who migrated to cities tended to be in the beginning of their reproductive period, considerable natural increase could occur in urban areas. Therefore the Philippines needed to devise a strategy for reducing fertility among migrant women as well as strategies for other groups such as professional/career oriented women and women who remained at home to tend to children and/or the home.     

Is There an Urban Advantage in Child Survival in Sub-Saharan Africa? Evidence From 18 Countries in the 1990s

Evidence of higher child mortality of rural-to-urban migrants compared with urban nonmigrants is growing. However, less attention has been paid to comparing the situation of the same families before and after they migrate with the situation of urban-to-rural migrants. We use DHS data from 18 African countries to compare child mortality rates of six groups based on their mothers’ migration status: rural nonmigrants; urban nonmigrants; rural-to-urban migrants before and after they migrate; and urban-to-rural migrants before and after they migrate. The results show that rural-to-urban migrants had, on average, lower child mortality before they migrated than rural nonmigrants, and that their mortality levels dropped further after they arrived in urban areas. We found no systematic evidence of higher child mortality for rural-to-urban migrants compared with urban nonmigrants. Urban-to-rural migrants had higher mortality in the urban areas, and their move to rural areas appeared advantageous because they experienced lower or similar child mortality after living in rural areas. After we control for known demographic and socioeconomic correlates of under-5 mortality, the urban advantage is greatly reduced and sometimes reversed. The results suggest that it may not be necessarily the place of residence that matters for child survival but, rather, access to services and economic opportunities.     

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.     

Residence background and fertility in Greater Bombay

Abstract The residence background of wives who migrate to metropolitan areas plays an important role in determining their fertility. From the data collected during 1966, relating to 7,872 currently married women of Greater Bombay, an attempt was made to establish differentials in marital fertility by residence background of the wives. This was categorized into three groups - non-migrants, urban migrants and rural migrants. It was observed that rural migrant wives exhibited significantly higher fertility compared with the other two groups, and this was explained by their lower educational attainment. Between the non-migrant and the urban migrant wives the latter consistently showed lower fertility for all age groups up to 40, while there was a reversal in the age group 40 and above, where non-migrants exhibited lower fertility. The urban migrant wives showed a somewhat higher level of education, most likely on account of selectivity, compared to the non-migrants. However, presence of a sizeable number of Parsee wives, characterized by a distinct urban culture and considerably lower fertility, was largely responsible for the low fertility of the non-migrant wives in the age group 40 and above. The variable that has emerged as the most influential in creating fertility differentials is education of the wife, which is shown to be negatively associated with the level of fertility. Wife's education explains to a large extent the observed fertility differentials by residence background.     

Migration Processes,Familial Characteristics,and Schooling Dropout Among Black Youths

This study uses data from the 2000 U.S. census to examine whether the schooling advantage of black immigrants’ children found in previous studies is robust. According to the results, the advantage associated with having migrant parents is not restricted to the children of immigrants. Black migrant parents, regardless of foreign-born status, have children with favorable schooling outcomes. Such parental-level influences, however, seem stronger among some immigrant groups than among native internal migrants. The study also suggests that the collective advantage of the children of immigrants is driven by positive migrant selectivity. Accordingly, comparisons between the children of native migrants and children in various immigrant groups reveal that the immigrant advantage is not robust. In fact, the results suggest that when immigrant ethnicity is considered, some children of immigrants may be disadvantaged relative to the children of native migrants. Among recent migrants, the children of native internal migrants also have more favorable outcomes than the children of immigrants, although these differences disappear after background factors are controlled. Further, internal-migrant and immigrant households are less likely to have characteristics that adversely affect schooling than nonmigrant households. Unsurprisingly, the children of nonmigrants have the worst outcomes among black youths.     

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.     

Interdivisional migration differentials by education for groups of selected SMSA’S,United States, 1960

An attempt is made to investigate the educational differentials between various types of interdivisional migrants and nonmigrants in selected Standard Metropolitan Statistical Areas (SMSA’s) of the United States. The analysis is carried out for four color-sex groups standardized for age. We have been able to identify three distinct patterns of migration differentials by education, that is, the J-shaped, the U-shaped, and the reverse J -shaped distributions. The tendency for migrants to be better educated than nonmigrants, by and large, has received support from the data we have analyzed. Wherever this tendency has not been confirmed, the main factors which, we believe, have influenced the differentials are the proportion of foreign-born whites, the geographic location of the places of origin and destination, and the differences in levels of educational attainment.     

Bombay migration study: A pilot analysis of migration to an Asian metropolis

This paper reports on a pilot study of migration to Greater Bombay, initiated on the recommendation of the Population Commission of United Nations, and utilizes both published tables from the 1961 Census of India and a set of specially prepared tables from the same census. Migrants were defined by birthplace and cross-classified by age and duration of residence in Bombay.Data (1901-61) on net migration (obtained from successive age-sex distributions) are analyzed in terms of underlying trends to give historical perspective to the analysis of recent data with special emphasis on changes in industrial and occupotiona structure.For the 1951-61 decade, the extensiveness of out-migration of former in-migrants, its age-sex selectivity, and its high incidence among recent migrants are demonstrated. As is true elsewhere, migration to Bombay is shown to be highly selective for ages of maximum economic activity. Migration streams to Bombay were preponderantly male, and, among males, the married segment predominated. The propensity to migrate was unusually high among minority religious groups. As to educational level, migrants were superior to the general population at origin but inferior to nonmigrants residing in Bombay. The work participation rates of migrants were higher for every age group than for resident nonmigrants; the proportion of employees was higher; and there was evidence of migrant concentration in industries and occupations requiring less skill, less education, and less capital than was true of nonmigrants. There were significant tendencies toward "division of labor" among various migration streams on the basis of skills and abilities acquired not only by formal education but also through tradition and precept. From the standpoint of the promotion of social change, the large volume (and selectivity) of reverse or return migration is especially note-worthy.The paper concludes with a methodological evaluation of the reliability and validity of duration-of-residence data and indicates that the relatively simple techniques of enumeration and tabulation utilized in this pilot study may have wide applicability in other developing countries.     

Men’s Migration and Women’s Fertility in Rural Mozambique

Labor migration profoundly affects households throughout rural Africa. This study looks at how men’s labor migration influences marital fertility in a context where such migration has been massive while its economic returns are increasingly uncertain. Using data from a survey of married women in southern Mozambique, we start with an event-history analysis of birth rates among women married to migrants and those married to nonmigrants. The model detects a lower birth rate among migrants’ wives, which tends to be partially compensated for by an increased birth rate upon cessation of migration. An analysis of women’s lifetime fertility shows that it decreases as the time spent in migration by their husbands accrues. When we compare reproductive intentions stated by respondents with migrant and nonmigrant husbands, we find that migrants’ wives are more likely to want another child regardless of the number of living children, but the difference is significant only for women who see migration as economically benefiting their households. Yet, such women are also significantly more likely to use modern contraception than other women. We interpret these results in light of the debate on enhancing versus disrupting effects of labor migration on families and households in contemporary developing settings.     

教育不平等与外来工工资的民族差异——兼论少数民族外来工教育获得的“三重弱势”

外来工工资收入的民族差异一直没有引起学术界的充分关注。2010年珠三角和长三角外来工问卷调查显示,少数民族外来工月平均工资为1636．16元,比汉族低约300元,差距显著。Oaxaca—Blinder模型分解表明,个人特征、企业特征、来源地等变量共解释了少数民族外来工与汉族外来工资差异的58．9％,其中主要来自于前劳动力市场阶段的教育不平等。导致少数民族外来工教育落后的原因是他们主要来自西部农村地区,当地经济发展水平和教育投入水平相对落后,而少数民族的语言和风俗习惯也影响到少数民族外来工的教育成就。     

Rural-to-Urban migration and child survival in Senegal

Analysis of the 1986 Senegal Demographic and Health Survey reveals that mothers may be able to improve their children's survival chances by migrating from the countryside to the city. Children of urban migrants, however, continue to experience a much higher risk of mortality before the age of 5 than children of urban nonmigrants, even after the mother has lived in the city for several years. This migrant mortality disadvantage persists when controlling for numerous socioeconomic and fertility-related factors typically associated with child mortality in developing countries, which also serve as indicators of migrant selection and adaptation.     

Christian–Muslim differences in child survival in Egypt

Ethnic and religious inequalities in child survival have been documented in many countries. In Egypt, during the 1980s and 1990s, Christians had higher childhood mortality than Muslims despite their higher socio-economic status (SES) and concentration in urban areas. This paper explores reasons for this Christian–Muslim mortality gap. Data for this study are drawn from Egypt’s 1988, 1992, 1995, 2005 and 2008 Demographic and Health Surveys, which recorded the respondents’ religious affiliation. The main analysis compares children of Christian and Muslim mothers in survival to age five using proportional hazards Cox regression models. Results indicate that differences in the regional distributions of Christians and Muslims positively contributed to the mortality gap during the 1980s–1990s. The majority of Christians resided in Upper Egypt where childhood mortality rates were considerably higher than in other regions. However, only part of higher Christian mortality can be explained by their regional concentration. In Upper Egypt, despite their higher SES, as well as greater urban residence, Christians had higher mortality than Muslims. These findings are at odds with research demonstrating the significance of SES and urban concentration in explaining ethnic–religious mortality gaps.     

Migration and the latino family: The union formation behavior of Puerto Rican women

This study examines the transition to first union among Puerto Rican women. I argue that understanding the behavior of mainland Puerto Ricans requires attention to family patterns in Puerto Rico and to the dynamics of migration between Puerto Rico and the United States. The study therefore is based on pooled data from comparable surveys undertaken in the two settings. These data allow for event history analyses that compare the union formation behavior of migrants with that of nonmigrants, and consider the role of migration in producing the observed union patterns. Multivariate models show that migrants are more likely than nonmigrants to form unions early and to enter informal unions. Additional analyses show that selective migration plays a role in producing this pattern. Overall the findings demonstrate the importance of using data from both origin and destination locales for understanding the behavior of migrant groups.     

Women’s employment, religion and multiculturalism: Socio-demographic emphasis

Giving the central focus to ‘religious affiliation’ which ‘was once at the forefront of demographic research (McQuillan 2004: 25), this paper examines the association between religion and women’s market employment. Generally speaking, gender characteristics such as high fertility and low employment levels for Muslim women in both intracountry and worldwide comparisons have been asserted in an extensive literature. The context, method and comparison groups of this study provide the opportunity to examine the longstanding debate as to whether religionper se or other determinants explain such gender characteristics in Islamic settings. It is, however, acknowledged that the present study faces limitations mainly associated with the selectivity of migrants. Using logistic regression and the multicultural context of Australia containing a substantially diverse ethnic composition of Muslims, this paper highlights Muslim/non-Muslim employment differentials. The paper also analyses the employment level of Muslim women across the regions of origin representing various contexts in order to provide empirical evidence to examine the above debate.     

Tracking rural-to-urban migration in China: Lessons from the 2005 inter-census population survey

We examined migration in China using the 2005 inter-census population survey, in which migrants were registered at both their place of original (hukou) residence and at their destination. We find evidence that the estimated number of internal migrants in China is extremely sensitive to the enumeration method. We estimate that the traditional destination-based survey method fails to account for more than a third of migrants found using comparable origin-based methods. The ‘missing’ migrants are disproportionately young, male, and holders of rural hukou. We find that origin-based methods are more effective at capturing migrants who travel short distances for short periods, whereas destination-based methods are more effective when entire households have migrated and no remaining family members are located at the hukou location. We conclude with a set of policy recommendations for the design of population surveys in countries with large migrant populations.

我国人口流动中的健康选择机制研究

利用2008年中国流动与健康调查数据,对农村留守人口、农村外出返乡人口、乡城流动人口以及城镇居民等不同流动特征群体之间的健康差异进行比较,并系统检验了我国人口流动过程中的两种健康选择机制——"健康移民"(healthy migrant)效应和"三文鱼偏误"(salmon bias)效应。模型分析结果表明,我国人口流动存在着较为明显的"健康移民"和"三文鱼偏误"选择效应。在控制被访者的年龄、性别、主要社会经济特征以及相关健康行为后,流动人口自评一般健康、慢性病状况、经常性身体不适和肺活量等健康指标显著优于农村留守人口,乡城流动人口患有慢性病和出现经常性身体不适的可能性也显著低于农村返乡人口。在控制相关变量后,乡城流动人口与城镇居民的健康状况(除慢性病和心率过高症状外)不存在显著差别。     

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.     

The differential migration of population in China: the analysis on sample survey data on urban population migration in 74 towns]

The paper analyzed data from a migration survey in 74 Chinese cities and towns in 1986. Several characteristics of the migrant population were found from the data analysis. The biggest proportion of migrants was in 20-24 age group. This age group sent 26.1% of the migrants to metro-cities, 27.6% to large cities, 25.1% to median sized cities, 22.4% to small cities, and 22.2% to towns. Migrants in the 15-29 age groups accounted for 50% of the migrants to different-sized cities and towns. Female migration is 4.2-15.4% lower than male. The proportion migrating because of marriage ranged between 84/7-92.5% to different-sized cities for females, which is much higher than for males. The level of education in the migrant population is higher than in the general population, as educational qualifications are important for job opportunities. Those with middle school and above education, make up the bulk of the migrants, and 30-40% of the migrant population to big cities increased their educational level after migrating. The currently and never married comprise, the majority of the migrant population, while the number of widowed and divorced is minimal (2 and 0.4%, respectively). Most of the widowed were 60 years old and migrated for subsistence to cities where their children lived. Among the unmarried migrants, female make up 1/3. Whereas among the married, there are more females than males.
