- Background Paper - Data and analysis: Partnering to better understand and address the human development implications of migration (UNDESA Population Division 2010)
This paper provides an overview of major data sources and examples of best practice regarding data dissemination, capacity-building, and research and analysis in the field of international migration. It also reviews the contributions of GMG members to the improvement of migration data and to policy-relevant migration research, discusses the obstacles that still remain to be surmounted, and suggests ways to address them.
This publication examines historical and recent levels and trends in international migration, including refugee flows, its economic and social effects, international migration policies, and the state of international cooperation in the field. The publication is also available in French and Spanish.
The 2009 Report starts with the point that the large inequalities in the global distribution of opportunities are a major driver for movement of people. The main message is that mobility has the potential to enhance human development - among movers, those who stay and destination communities. In practice, however, processes and outcomes can be adverse to movers, and there is an important role for better policies and institutions at the national, regional and international levels.
As UNHCR commemorates in 2011 the 60th anniversary of the 1951 Convention Relating to the Status of Refugees and the 50th anniversary of the 1961 Convention on the Reduction of Statelessness, this report demonstrates the continued relevance of forced displacement and statelessness to the international agenda. It depicts some of the major humanitarian trends that occurred during 2010 in relation to displacement, either within or beyond international borders. The report also reviews statistical trends and patterns for populations considered to be of concern to UNHCR - refugees, returnees, stateless persons and internally displaced persons (IDPs) - collectively referred to as “persons of concern.”
This 2010 Statistical Yearbook presents statistics on trends in displacement, protection and solutions for persons of concern to the UNHCR.

The main purpose of this book is to suggest concrete ways in which the international community can begin to address the huge gaps in our knowledge relating to the likely impact of climate change on migration. The book does this by taking stock of the existing evidence on the effects of climate change and environmental degradation on migration, providing a comprehensive overview of the findings of recent research studies. Throughout, the focus is on how research can best inform policy and provide the evidence that decision-makers will need in the future to plan for and respond to environmentally induced migration.
This publication provides an analysis of recent developments in migration movements and policies in OECD countries and two analytical chapters, covering migrant entrepreneurship and international migration to Israel.
Responding to the demand for evidence-based policies, this report provides a review of sources and quality of statistics on international migration in selected countries of the Commonwealth of Independent States (CIS): Azerbaijan, Kazakhstan, Kyrgyzstan, the Russian Federation, and Tajikistan.
- Old and New Topics in the Estimations of International Migration in Latin America and the Caribbean (in Spanish) (CEPAL 2011)
Changes in population dynamics and migration patterns prevailing in the countries of Latin America and the Caribbean have brought new requirements to the estimates of international migration. This paper addresses this problem from several aspects. It also acknowledges the existence of a Latin American tradition for the measurement of international migration that is centered on population censuses, discusses the core of variables traditionally used for the study of migration, and considers the existing international and regional recommendations regarding this issue.
