The concept of international migration as reflected in data collection systems

The problems of statistics relating to international migration have been well documented. It is a fact that the concepts of legal nationality, residence, place of birth, time, and purpose of stay underlying those statistics vary considerably, not only between countries but even within countries through time or between different sources of information within the same country. The crusade to achieve greater homogeneity in the concepts underlying flow statistics on international migration was started at least 55 years ago, but despite some encouraging developments, it is unlikely that homogeneity will be achieved during the rest of this century. This article analyzes how these 5 basic concepts are used to characterize migration. Statistical systems generally use at least 1 or more of these concepts to identify migrants from other international travelers. A review of these basic concepts reveals the great influence that legal or regulatory considerations exert, whether explicitly or implicitly, in their definitions. Perhaps one of the most serious problems in understanding how migration is viewed and measured by national statistical systems is to disentangle the legal or quasilegal nature of certain concepts from those that can be taken at face value. The tendency to sift from their meaning all legal impurities and thus transform them into reflections of actual events operates under the assumption that migrants are free agents, able to determine their durations of stay, absence, or the type of work that they will perform. In reality, the freedom of migrants stops where the State's prerogatives start, and statistics often reflect an uneasy compromise between the 2. Despite their many deficiencies, statistics on international migration are a rich source of information, not only about quantitative aspects of the process, but also about how the process is conceived by their generators. A careful evaluation of their meaning, scope, and limitations can be, therefore, a rewarding exercise.     

The United Nations recommendations and data efforts: international migration statistics

This article reviews the UN's efforts to improve international migration statistics. The review addresses the challenges faced by the UN, the direction in which this effort is going, gaps in the current approach, and priorities for future action. The content of the UN recommendations has changed in the past and seems to be moving toward further changes. At each stage, the direction of change corresponds broadly to earlier shifts in the overall context of world social-economic affairs and related transformations in international travel and migration patterns. Early (1953) objectives were vaguely stated in terms of social, economic, and demographic impacts of long term settlement. 1976 recommendations continued the focus on long term resettlement and, at the same time, gave more attention to at least 1 kind of short term (work-related) movement. Most recent recommendations have given more attention to other classes of short term travellers, such as refugees and contract workers. Recommendations on the measures and data sources have changed over time, also. The 1953 recommendations were limited to flow data from international border statistics. 1976 recommendations drew attention to stock data and the use of civil registration data to supplement border crossing data. Recent UN reflections recognize that the volume of border crossings has now reached the point where many countries simply refuse to gather data on all travellers, choosing instead to make estimates. It is implied that either sample surveys at border points and/or visas and entry permits may be the best way of counting various specific kinds of migrants. Future recommendations corresponding to contemporary and emerging concerns will require that the guidelines be restructured: 1) to give more explicit attention in international migration statistics to citizenship and access to political and welfare benefits; 2) to distinguish more carefully various sub-classes of movers; 3) to expand objectives of data collection to include an assessment of social impacts to complement the current focus on demographic and economic impacts; 4) and to give more careful attention to ways of estimating undocumented migrants and workers within large streams of other travellers.     

The crisis of international migration in an integrating West Africa: a case study of Nigeria and Ghana

The mass expulsions of illegal immigrants that have taken place in recent years in Western Africa are examined, with particular reference to those in Ghana in 1969 and Nigeria in 1983. The author considers "the context within which they have taken place, including some of the longterm causes, and the systematic nature of the migrations which preceded them; the ways in which these have been handled by the states concerned; and their implications for the rights and status of migrants as a particular form of exploited labour within the development process in the subregion."

Research on international migration and census data co-operation in Latin America

Population censuses in Latin America have generally recorded the place of birth of all persons enumerated. The use of those data for the study of international migration has been less common because international movements were judged to be a relatively weak factor determining demographic change in the majority of Latin American countries and because the data gathered were generally not tabulated with sufficient detail. During the 1970s, the UN Latin American Demographic Center (CELADE) realized that international migration was not necessarily a minor factor in their evolution and launched a program to improve the quality and availability of census information on the foreign-born population enumerated by each country. The program on International Migration in Latin America (IMILA) has therefore been in operation for more than 10 years and has been successful in eliciting the in-depth tabulation and exploitation of census information in the majority of Latin American countries and in the 2 main receivers in the Americas: Canada and the US. As part of the IMILA project, CELADE has become the depository of magnetic tapes with census information on the foreign-born population, thus gaining greater flexibility in the exploitation of the data available. On the basis of the information gathered, CELADE has published twice in the past decade a compilation of tabulations of the foreign-born population by country of enumeration, country of birth, age, and sex. Although census data on place of birth are not free from problems, particularly in countries where illegal migrants may not be adequately enumerated by a census, they are a valuable source of reasonably comparable information on the overall impact of migration in receiving countries and are often the only source of information on emigration from the sending countries.     

The measurement of international migration in Belgium

This article examines legislation affecting international migration in Belgium from the perspective of 2 questions: 1) What types of migrants are definable by legislation? and 2) What kinds of documents may be utilized to compile statistics on international migration? The following are some of the article's main points. 1) Since January 1, 1847 each communal administration in Belgium has maintained a national population register that details births, deaths, marriages and household structures, and all movements within 1 commune, from 1 commune to another, and movements between states. 2) When a Belgian citizen leaves for a foreign destination with the intention of settling there, his name is struck from the registers. 3) To enter Belgian territory, the alien must possess the documents required under bilateral agreements between Belgium and each of the states concerned. Generally, the alien must obtain a visa to his passport from 1 of the diplomatic or consular offices of Benelux before entering Belgium. The alien must have sufficient means of subsistence to avoid being considered in need. He must not be listed as an undesirable alien in Belgium, he must not have been convicted of a crime, and he must not constitute a danger to public order or national security, The alien also should not have been expelled from Belgium less than 10 years earlier. 4) Absence from Belgium and the right to return is granted to aliens holding a valid certificate of enrollment or a settlement card. 5) Any individual who has reason to fear persecution can obtain refugee status; his stay is protected until his application is declared to be unfounded by the High Commission. 6) The National Statistical Institute issues various types of data from which international population movements can be identified. The 2 main sources of these statistics are the population censuses held every 10 years and the annual demographic statistics. 7) In 1967, the Belgian Council of Ministers authorized the setting up of the National Register, a computerized and centralized population register that is the most important source of demographic information. Law requires that residents provide to the database their names and surnames, main residence, address, profession, nationality, civil status, composition of the household, place and date of birth, and place and date of death.     

The future of international labor migration

"The article reviews the nature of international labor migration today and the economic and political rationale for its occurrence. It suggests that while the developed economies will continue to attract and exchange highly skilled labor, they will have little need for mass immigration by those with low skill levels. In contrast, poorer countries with rapid population growth and low living standards will encourage emigration, except by the highly skilled. One consequence will be more illegal immigration."     

The international migration of nurses in long-term care

This article describes five major factors that are affecting patterns of international migration among nurses who work in long-term care settings: DEMOGRAPHIC DRIVERS: The aging of the populations in developed countries and the low to negative growth in the working-age population will increase the demand for international workers to provide long-term care services. GENDER AND RACE: A dual labor market of long-term care workers, increasingly made up of women of color, is becoming internationalized by the employment of migrating nurses from developing countries. CREDENTIALING: The process of credentialing skilled workers creates barriers to entry for migrating nurses and leads to "decredentialing" where registered nurses work as licensed practical nurses or aides. COLONIAL HISTORY AND GEOGRAPHY: The colonial histories of many European countries and the United States have increased migration from former colonies in developing countries to former colonial powers. WORKER RECRUITMENT: Efforts to limit the recruitment of health care workers from some developing countries have had little effect on migration, in part because much of the recruitment comes through informal channels of family and friends.     

Trends of international migration since 1965: what existing data reveal

Relying on data from a variety of sources, this article sketches the main trends of international migration during 1965–1996, thus documenting the changes that both the character and the direction of international migration have undergone over the course of time. In doing so, it provides a quantitative basis to assess the validity of certain common tenets regarding the evolution of migration at the end of the twentieth century.
The article concludes that the changes observed are generally less striking than usually claimed, although major historical events, such as the end of the cold war and the transformations it entailed, have had a determining influence in shaping many of the key migration movements occurring since 1985.
In particular, migration originating in the former Eastern bloc countries increased markedly and the dynamics of population mobility within the former Soviet space underwent important modifications. In addition, the end of the bi-polar era allowed the resolution of some long-standing conflicts that permitted the repatriation of large numbers of refugees.
However, the proliferation of ethnic or civil conflict that has accompanied the nation-building process in several regions has led to a series of forced migration movements. These developments plus the social, economic and demographic differentials that persist between countries at different levels of development have continued and will continue to fuel international migration.
By reviewing the quantitative evidence available at the regional level, this article sets recent developments in perspective.     

Economic theory and international migration

The modern literature on the economics of immigration focuses on 3 related issues: 1) what determines the size and skill composition of immigrants flows to any particular host country; 2) how do the immigrants adapt to the host country's economy; and 3) what is the impact of immigrants on the host country's economy? This article reviews the theoretical framework and empirical evidence provided by the economics literature on these questions. It demonstrates that the economic approach, using the assumption that migration behavior is guided by the search for better economic opportunities and that the exchanges among the various players are regulated by an immigration market, leads to substantial insights in to these issues.     

Environmental concerns and international migration

"This article focuses on international migration occurring as a result of environmental changes and processes. It briefly reviews attempts to conceptualize environment-related migration and then considers the extent to which environmental factors have been and may be significant in initiating migration. Following is an examination of migration as an independent variable in the migration-environment relationship. Finally, ethical and policy dimensions are addressed."     

Broadening the scope: Gender and international economic development

The central claim of this essay is that gender is a key term for understanding economic development insofar as it reveals fundamental aspects in the organization of production and labor. Following a cursory review of influential approaches to development and their relationship to the parallel theorization of gender, I compare two recent modalities of industrial restructuring: the expansion of export-processing plants (maquiladoras) along the U.S.-Mexico border and the survival strategies of electronics firms in Southern California. My theoretical focus is on the specification of gender as a process that allows for the maintenance of a substratum of labor, predominantly female, outside of market exchanges. That labor is recurrently tapped by employers seeking competitive edges in domestic and international markets. The same mechanism enables the replication of patterns of unequal exchange through the articulation of two interdependent models of production — one domestic and one market oriented — by which capitalist accumulation is fulfilled.     

The Philippine national recording systems on international migration

The author reviews migration data sources and government collection agencies in the Philippines. He finds that "despite the importance of international migration for national policy, efforts to correct the serious data limitations in the area of migration statistics have been limited and uncoordinated. In fact, most estimates of emigration levels from the Philippines still rely heavily on the data gathered by receiving countries."     

Managing international migration in developing countries

IOM's research project on emigration dynamics in developing countries, launched in 1993, brought together teams of researchers in four regions of the developing world: Sub-Saharan Africa; South Asia; the Arab region; and Mexico, Central America and the Caribbean. The article reports the findings of team members as reported to, and discussed by, 180 participants, including those from 57 governments, at IOM's twelfth Migration Seminar held in Geneva during April 1997.
The research had been carried out under a common conceptual framework which addressed emigration dynamics through changing economic, demographic, political and ecological circumstances in each country or subregion; the role of networks already established between persons in sending and receiving countries; and the nature of entry restrictions imposed by receiving countries.
A central objective of the research was to try and measure interaction between the variables in specific country and subregional situations and, as far as possible, provide results that could assist policy makers in both developing and developed countries. This objective had been facilitated by workshops held in each region during 1995–96 comprising researchers, officials and policy makers.
Although economic, demographic, political and ecological circumstances varied considerably between countries in the four regions, conference delegates agreed that the approach adopted by the researchers, including contact with officials and policy makers, had provided new insights into the emigration dynamics process.
Recommendations made during conference discussions included the need to establish an effective system of migration information exchange between and across regions; that on the basis of results achieved so far research on emigration dynamics should be continued and broadened; and that there should be sustained dialogue between policy makers, officials, researchers and NGOs.     

Contemporary trends in international migration study

Recent trends in international migration are reviewed. Three major trends are identified: changes in the relationships between states due to the presence of a more or less permanent minority population from one state in the other; the flow of illegal migrants despite stricter immigration laws; and the growing problem of refugees and their impact on the migration policies of developed countries. The author reviews some theories concerning international migration and the role of institutions in the international division of labor. (SUMMARY IN FRE AND SPA)     

Environmental and ethical aspects of international migration

"U.S. immigration policy has a beneficent intent. However, recent work suggests that the signal it sends internationally--that emigration can be relied upon to relieve local (Third World) population pressure--tends to maintain high fertility rates in the sending country. This effect is counterproductive because high fertility is the primary driver of rapid population growth. In addition, it appears that the relatively open U.S. immigration policy has resulted in a rate of domestic population growth that threatens both the well-being of American labor and cherished environmental values."     

Future trends in international migration to Europe

The author discusses future trends in international migration to Europe, with a focus on the impact of the economic situation on labor force needs and resources. Aspects considered include changes in foreign direct investments, changes in the size of the European labor market, and the potential emigration of the labor force in underdeveloped countries.     

Comparing European and North American international migration

International migration is a vast, complex, and heterogeneous field of study. It requires not only knowledge about dynamic processes in the past and at present and in various regions of the world, but also interdisciplinary cooperation, not least in order to achieve a good theoretical development. Theories about international migration tend to be built on particular periods or regions. The test of these theories comes through comparative research. A comparison of North American and European immigration and immigration policy could examine 1) whether immigration is permanent or temporary, 2) the desire of Europeans for short-term immigration to allow the integration of the large numbers of immigrants from the recent past, 3) the differential development of welfare states, 4) the likely long-term outcome of large waves of immigration, and 5) the legal status of aliens.     

On interrelations between internal and international migration

International migration represents just one type of spatial population mobility, along with inter‐regional, rural‐urban, or intra‐urban migration. The possible connections among various forms of migration are, however, only rarely traced in the professional literature on the political and social determinants as well as consequences of international migration. Against this background, an attempt is made in the present paper to identify possible associations between internal and international migration in the case of Poland.     

Immigration history and the future of international migration

"International migration must be understood as a permanent phenomenon rather than as a temporary movement. In this article, the author proceeds from the premise that in appreciating the relation between the past and the present, we may be able to draw on 'lessons of the past' to modify our definition and perception of current problems and to analyze possible policies and decisions. The article is divided into several sections, historical changes within migration patterns including different categories of migrants, various phases within the migration process in recent history, theoretical considerations in analysis, distinct types of immigration policies pursued by various states, and current and possible future trends."
