Relative deprivation and international migration.

This article provides theoretical reasoning and empirical evidence that international migration decisions are influenced by relative as well as absolute income considerations. Potential gains in absolute income through migration are likely to play an important role in households' migration decisions, but international migration by household members who hold promise for success as labor migrants can also be an effective strategy to improve a household's income position relative to others in the household's reference group. The findings reported in this article provide empirical support for the hypothesis that relative deprivation plays a significant role in Mexico-to-U.S. migration decisions. The findings also suggest that this migration is an effective mechanism for achieving income gains in households that send migrants to the U.S. and that households wisely choose as migrants those of their members who are most likely to provide net income gains.

International migration and control of communicable diseases.

The epidemiology and policy implications of communicable disease (CD) transmission associated with international migration have received little systematic study. This is a review of clinical and epidemiological reports in search of strategies to assess and manage the impact of international migration on the transmission of CDs. The economics and demography of migration from less developed to industrialized nations is considered. Migration-related transmission should differentiate between actual transmission as opposed to geographic relocation of disease. Limitations of current screening and disease prevention strategies are discussed. Social and ecological processes through which migration can contribute to increased CD transmission are described, including placement in refugee camps, unclear legal status of migrants in recipient nations, and temporary return migration. Strategies for non-discriminatory and non-punitive control of migration-related CDs, needed changes in clinical practice, and complexities presented by CDs of long latency (such as HIV infection) are reviewed.

Nativity concentration and internal migration among the foreign-born.

Are immigrants who live in states where large numbers of their compatriots reside more or less likely to migrate than those who live in other states? Using 1980 U.S. Census data to address that question, the analysis shows that nativity concentration deters interstate migration but not migration within the same state. Residing in a state where fellow nationals live is a more important determinant of internal migration than human capital, immigration status, or a state's unemployment rate. New York State residence in 1975 also promotes interstate migration. This research suggests that social dimensions should be taken into account in modeling internal migration of the foreign-born.

Can patient registers give an improved measure of internal migration in England and Wales?

This article describes a new source of internal migration data for England and Wales. These data are extracted from the 98 Family Health Service Authority (FHSA) patient registers that hold the details of people in England and Wales who are registered with the National Health Service. Migration estimates are derived from changes in postcodes on the patients' records. The findings presented in the article show that the registers provide high quality estimates of migration into and out of the constituent areas of the FHSAs (as compared to other sources). Where limitations are identified, compensatory adjustments can be introduced to further enhance the quality of the estimates.

International migration and development in Mexican communities.

The theoretical and empirical literature generally regards international migration as producing a cycle of dependency and stunted development in sending communities. Most migrants' earnings are spent on consumption; few funds are channeled into productive investment. We argue that this view is misleading because it ignores the conditions under which productive investment is likely to be possible and profitable. We analyze the determinants of migrants' savings and remittance decisions, using variables defined at the individual, household, community, and macroeconomic levels. We identify the conditions under which U.S. earnings are repatriated to Mexico as remittances and savings, and indicate the factors leading to their productive investment.

Transitional society, health status and international migration of Muslim villagers in the lower part of southern Thailand.

A survey was carried out in a Malay-speaking Muslim community in southern Thailand to obtain baseline data for planning of long term multidisciplinary research and development. By using a 30-cluster sampling technique, 210 households of 1,308 subjects were studied in the post-Ramadan period. It was found that the community was in a social transition. The crude birth rate was 4% and 37.6% of the households had at least one migrant. About half of these migrants had been to Malaysia and mainly worked in rubber plantations. Ninety-five per cent of the households had electricity whereas only 23.8% had a latrine. Boiled or rain water was regularly drunk in only 13.3 per cent of the households. Home-grown agricultural products were not sufficient to provide adequate food. Twenty-six per cent of the adults were unemployed and 24.6% were illiterate. Of the pregnancies 26.7% had no antenatal care and complete tetanus toxoid was given to only 27.8%. Traditional birth attendants conducted 81.1% of the deliveries and only 28.9 and 24.4% of the umbilical cords were correctly cut and correctly dressed, respectively. Breast feeding was still a common (87.8%) practice. However, complete immunization was given to only 10.8%, and 37.8% of the infants had at least one diarrheal episode in the previous month. It was concluded that high birth rate, high migration, low education, low income and bad health of infants are major problems. These problems were interlinked and needed a special multidisciplinary approach. In addition to common obstacles for routine health delivery, migration may create international complications, particularly related to maternal and child care.

Tuberculosis control in Europe and international migration.

This is a consensus-based position paper of a Task Force, comprising representatives of nongovernmental and governmental organizations in the European Region of the International Union Against Tuberculosis and Lung Disease and the World Health Organization, on tuberculosis control in the countries of Europe and international migration. Tuberculosis among the foreign population entering European countries represents an increasing and important proportion of all tuberculosis cases reported in these countries. Adequate surveillance systems allow the identification of population segments at an excess risk of tuberculosis compared to the general population. Among groups of foreigners with a risk considerably exceeding that of the general population, screening for tuberculosis and infection with M. tuberculosis yields a large number of persons in many countries who can benefit from curative and preventive interventions. The Task Force recommends that European countries: 1) have notification systems based on both mandatory laboratory and physician reports of tuberculosis cases, to allow identification of population segments at an excess incidence of tuberculosis compared to the general population; 2) consider screening of high incidence and prevalence groups among the entering foreign population for tuberculosis and infection with M. tuberculosis amenable to curative and preventive i intervention; 3) utilize existing governmental and nongovernmental organizations to provide culturally and socially sensitive services to ensure proper follow-up and implementation of interventions; 4) provide comprehensive curative and preventive services to treat tuberculosis; and 5) evaluate efficiency and efficacy of screening procedures on an ongoing basis.

Changing patterns of internal migration 1970-1990: a comparative analysis of Jews and whites in the United States.

Independently conducted yet complementary sets of data from the 1970/1971 and 1990 National Jewish Population Surveys and the U.S. censuses of the same years were used to analyze changes in the internal migration of Jews and whites during the periods 1965-1970(1971) and 1985-1990. Interstate lifetime and five-year migration rates among Jews increased to levels significantly surpassing those of whites. Adjusting Jewish migration rates for the educational achievement of their white counterparts did not have much of an effect on lifetime migration or on the recent migration of the 1970/1971 Jewish population; however, it accounted meaningfully for the migration propensities of Jews in the period 1985-1990. These findings suggest that socioeconomic status has begun to play a larger role in promoting different migration patterns than in promoting ethnic group differences. Further, the direction of Jewish migrations followed those of whites (i.e., from the North-east and Midwest to the South and West): and due to their higher migration rates, Jews have considerably narrowed the regional distribution differences between themselves and whites. I interpret these results as evidence of the weakening role of ethnicity in present-day America.

Dietary habits, internal migration and social class in a sample of a northern Italian population.

The study of migrants has generated interesting hypotheses on the etiology of different types of cancer. In particular, it has been suggested that both colon and breast cancer could be related to living conditions, including diet, in the country of immigration. Considerable internal migration occurred in Italy in the sixties. We studied a random sample of 1,400 subjects living in the city of Torino and the province of Varese. They were interviewed with a detailed questionnaire about their dietary habits, and the consumption of several nutrients was considered according to the area of birth and social class. The hypothesis we tested was whether, after controlling for social class, there were different dietary habits among the migrants and the native population, and whether such differences could help in the formulation of etiologic hypotheses on cancer. We found that the intake of saturated fatty acids and cholesterol was lower among the migrants from the south, whereas they consumed higher levels of vegetables than people born in the north. The different intake of saturated fatty acids and cholesterol seemed to be attributable mainly to the consumption of butter, for which the south/north ratio was as low as 0.47 in men and 0.56 in women. Important gradients by social class were also suggested for several nutrients.

International migration and biodemographical behaviour: a study of Italians in Belgium.

This paper describes the matrimonial and reproductive behaviour of Italians who migrated to Belgium after the Second World War. Migrants were either already married, or later became married, to other Italians. Among the children of migrants, men equally chose Italian or Belgian wives but women tended to prefer Italian partners. Italian-Belgian marriages were more frequent among the better educated groups. Family size is smaller among migrants marrying after migration and in heterogamous marriages. Significant differences in birth intervals are found when marriage occurred before or after migration, between generations, and between homogamous and heterogamous marriages.

The impact of immigration on the internal migration of natives and immigrants.

In this paper we examine the internal migratory response, by native-born non-Hispanic white men and foreign-born men in the United States, to recent immigration. Our analysis does not support the claim that natives have made a migratory response to recent immigration. Native-born men and foreign-born men were less likely to leave states that received large numbers of immigrants in the 1980s than they were to leave other states, and native-born men had less propensity toward out-migration than did foreign-born men. Out-migration was most likely to be deterred if recent immigrants originated in Europe or Asia. Although native-born non-Hispanic white men showed a tendency toward out-migration if recent immigrants originated in Latin America or the Caribbean, this result was insignificant after we controlled for state economic and regional context.

DNA bound to polypyrrole films: high-resolution imaging, DNA binding kinetics and internal migration.

We have studied the time-dependent uptake of 35S radiolabeled DNA with electrochemically prepared polypyrrole films. The two distinct polypyrrole film surfaces, a rough (solution polymeric growth face, R) and a smooth surface (electrode face, S) were characterized by low-resolution AFM and high-resolution transmission electron microscopy (TEM). These studies showed the presence of steep contours and defects in the form of large and small surface holes and valleys on the rough surface of polypyrrole. The void dimensions ranged from the nanoscale to micron size. By contrast, the smooth surface was flatter and largely devoid of significant structural defects and exhibited closer packing of the polypyrrole chains over large areas. Both surfaces were comprised largely of chains whose average diameters were 1.0-1.2 +/- 0.3 nm. The surface characterization studies were complemented by time-dependent DNA uptake studies which showed a t1/2-dependent total uptake of 35S DNA at higher levels on the rough surface compared to the smooth surface. This is consistent with the apparent higher effective surface area of the rough surface compared to the smooth. Using a proportional counter the time-dependent ratio (R/S) of the 35S DNA detected from the rough surface of the polypyrrole disk to that detected from the smooth surface suggested that DNA was migrating into the disk interior from its uptake surface. The rough side defect dimensions measured by TEM were more than sufficient to allow for the penetration and migration of DNA into the disk interior. Both R/S ratios were extrapolated and found to intersect at an R/S value close to 1.0, suggesting a kinetic process leading ultimately towards a nearly uniform radiolabeled DNA distribution in the disk. These kinetic results were in agreement with the surface characterization studies and suggest a model in which sizeable internal pores exist throughout the electrochemically prepared polypyrrole, that could account for the DNA migration effect. This was confirmed by TEM of the interior of a polypyrrole disk produced by Argon ion milling.

Minor psychiatric morbidity and internal migration in Brazil.

Studies of non-psychotic disorders in migrants have shown inconsistent results. This paper reports the findings of a case-control study carried out in three cities in Brazil to investigate the association between migration and minor psychiatric morbidity (MPM). Two hundred and seventy-six cases and 261 controls were selected from a survey of 6740 people aged 15 years or more. Diagnoses were made using the DSM-III Symptom Checklist. A statistically significant increase in risk of MPM in migrants was found by univariate analysis [odds ratio (OR) = 1.76; 95% confidence interval (CI) = 1.21-2.57. After controlling for gender, age, educational level, marital status, place of residence and position in the labour market, the overall increase in risk of MPM disappeared (OR = 1.02; 95% CI = 0.64-1.64), but a statistically significant increase in risk was present only in migrant unemployed women. This finding did not support models that explain risk in migrants by viewing migration as associated with cultural change and stressful life events. On the other hand, models based on the concept of selection- displacement from the labour market are more consistent with the present findings.

International migration of health manpower in Sub-Saharan Africa.

This paper concerns itself with a few questions related to the impact of the emigration of health manpower on the health status of individuals and economic development of Sub-Saharan Africa (SSA). The paper evaluates the harmfulness of the migration from Sub-Saharan Africa. The analysis leads to some observations about the effect of the quality of the migration on Africa's health care system development and the appropriateness of some of Africa's policies for controlling the migration.

International migrations. A framework for directing research.

Current, large-scale, cross-cultural migrations offer promising research targets for the study of human adaptations. The opportunities for such research, however, remain substantially unused in the mainstream of psychology. The purpose here is to provide a framework encompassing components of the migration experience to aid such research. Contextual factors in the sending and receiving societies impinge on the components of the migration experience: social networks, socioeconomic status, and culture. The components, treated as intertwining transitional experiences in migration, should be juxtaposed in research to examine their effects. Gender and age mediate the effects. The framework aims to benefit research that implicates, directly or heuristically, the experiences of persons exposed to rapid sociocultural change and the consequences of such changes in their lives.
