International Migration Statistics: Guidelines for Improving Data Collection Systems
Since its creation in 1919, the ILO has devoted attention to international migration issues, including the availability and quality of international migration statistics. These guidelines aim to establish the basis for strengthening national capacities to generate the data required for policy analysis in the area of international migration. To this end, this book discusses the conceptual and analytical issues related to the measurement of international migration and their implications for the international comparability of international migration statistics. It then provides a critical review of the adequacy of current data sources on international migration and suggests ways of improving them so as to enhance their usefulness and international comparability.
A similar review has not been undertaken since at least 1949 when the UN issued the report, "Problems of migration statistics" (United Nations, 1949). Attention is also paid to the use of specially designed surveys to gather information for the analysis of the determinants and consequences of international migration. A better understanding of the processes giving rise to international migration flows and their consequences, for both migrants themselves and their communities of origin and destination, is crucial for developing realistic and effective policies. This book includes annexes presenting model questionnaires for use in surveys carried out in countries of destination and countries of origin.
