Using census and survey data to measure undocumented immigration and emigration for the United States.

The estimation of emigration and undocumented immigration rates for the United States is discussed. "A residual methodology compares census or survey data on the resident foreign-born population with an independently derived estimate of the legally resident foreign-born population. The difference is the estimated undocumented population which may be compared for alternative dates to derive measures of change. In 1988, this difference was 1.9 million, similar to the 1980 estimate of 2.1 million.... Measurement of emigration...has recently relied on resident reports of immediate relatives who have emigrated. Controlling for multiple reporting of the same emigrants, the direct estimate of the emigrant population from the United States is about 1.2 million. Allowing for undercoverage of the emigrant population due to nonresident relatives, there could be 2.0 million or more emigrants."

Symptoms of asthma, bronchial responsiveness and atopy in immigrants and emigrants in Europe. European Community Respiratory Health Survey.

Migration studies on asthma may provide information on its environmental causes. The European Community Respiratory Health Survey has potential advantages due to the number of countries involved, standardized collection of information, assessment of directionality of migration, and availability of physiological data on bronchial responsiveness and atopy. Prevalence rates of symptoms associated with asthma were compared for immigrants, emigrants and nonmigrants living in centres mostly in western Europe. Similar analyses were carried out for bronchial responsiveness (provocative concentration causing a 20% fall in forced expiratory volume in one second and slope) and atopy. Medication and use of health services were also explored. Overall, 1,678 (8.6%) of 19,516 participants were immigrants in the 18 countries participating in the study, of whom 581 were emigrants from one of the participating countries. Rates of asthma symptoms were higher in immigrants (odds ratio (OR): 1.21, 95% confidence interval (CI): 1.00-1.51) and emigrants (OR: 1.31, 95% CI: 0.96-1.51) compared to nonmigrants after controlling for area, sex, age and smoking status. However, bronchial responsiveness and atopy were equally distributed between immigrants, emigrants and nonmigrants. Use of health services was observed to be similar in migrants and nonmigrants with asthma. In the European Community Respiratory Health Survey, migrants reported more asthma symptoms, but had similar bronchial responsiveness, atopy, and use of health services when compared with the nonmigrant population.

Social Security and the emigration of immigrants.

Each year the Social Security Administration forecasts the financial status of the Old-Age, Survivors, and Disability Insurance (OASDI) programs by projecting trends in key variables such as the labor-force participation and earnings of the U. S. population. In the difficult task of projecting the long-term financial status of Social Security, assumptions are made concerning the relationship of immigrants to Social Security. An important aspect of that relationship is the emigration of immigrants. This article describes the general assumptions related to the level and timing of emigration that underlie projections of Social Security's financial status and examines how closely these assumptions fit research findings based on a variety of data sources. Previous trends in emigration and factors that may affect current and future levels of emigration are described. The article also presents theoretical expectations and empirical evidence concerning the timing of emigration.

Possible approaches to improving the international comparability of immigration and emigration statistics: an illustration of the Canadian situation

"This article seeks to highlight the extent of the lack of standardization which exists in the field of international migration statistics and, using statistics for Canada as an example, to illustrate how significant progress towards resolving this problem could be made if sufficient numbers of countries made their immigration and emigration statistics gradually comply more fully with the United Nations recommendations."

Emigration, return, immigration: a review and evaluation of Greece's postwar experience of international migration.

"This paper offers a review and evaluation of the Greek experience of international migration.... The analysis is based partly on available published data, and partly on qualitative appraisals. Three major international migration phases are analysed--emigration, return migration and immigration--and the main socio-economic and cultural effects of these migration trends are discussed. The paper pays particular attention to the recent mass immigration movements, noting their heterogeneity...and describing their impact on the Greek labour market. The article concludes with some comments on the difficulties of formulating a Greek migration policy in the light of the country's location, open borders and internationalized economy."

A parity-dependent immigration-birth-death-emigration process.

An immigration-birth-death-emigration process is studied when the immigration, birth, death, and emigration parameters depend on two parity classes of individuals, namely, zero and nonzero parity. The expected number of individuals in the population at time t and that of emigrants in (0,t) of both parity classes are obtained using the probability generating function (pgf) technique. The explicit expression for the pgf of the process is derived when the parameters are parity-independent. Population extinction and some limiting results are also discussed.

[Emigration and immigration in Greece: recent trends and political questions].

"In order to give an account of the migrations related to Greece, the Greek territory can be characterized by several attributes that account for the way in which a certain form of migration has been understood in relation to this country. Therefore, Greece can be spoken of, not only as a space of work, circulation, settlement, especially for the citizens of the EEC and for clandestine immigrants, but also as a space of retirement, retreat and transit, whether for refugees or for people belonging to a Greek minority.... We will attempt a statistical approach of the migratory phenomenon as well as a presentation of the figures for each country of origin, and a global appreciation of the economic and social importance of these migratory movements for Greece." The implications for migration policy are discussed. (SUMMARY IN ENG AND SPA AND ITA)

Return migration on the policy agenda in Sweden.

"Explicit policies on return migration are of rather recent date in most European countries, including Sweden. During the last few years a number of new policy initiatives have been taken in this field. The purpose of this paper is to examine how official Swedish policies on return migration have changed during the last 20 years. The conclusion is that Sweden has moved from a ¿non-policy' in the 1970s, much in opposition to ¿guestworker' or rotation systems, towards an active and explicit policy promoting return in the mid-1990s. The major trends in the country's immigration, emigration and return flows are also presented."
