International Migration Statistics: Guidelines for Improving Data Collection Systems
SUMMARY FROM BOOK: Since its creation in 1919, the International Labour Organization has devoted attention to international migration issues, including the availability and quality of international migration statistics. The present book continues that tradition. Its purpose is to set forth the basis for strengthening national capacities to generate the data required for policy analysis in the area of international migration. To fulfil its purpose, 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 sources of data on international migration and suggests ways of improving such data so as to enhance their usefulness and international comparability. A similar review has not been undertaken since at least 1949 when the United Nations issued the report entitled 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 interna- tional migration. A better understanding of the processes giving rise to international migration flows and their consequences, for both the migrants themselves and their communities of origin and destination, is crucial for developing realistic and effective policies. This book is divided into seven chapters, the first of which is this introduction. In addition, it contains annexes presenting model questionnaires for use in surveys carried out in countries of destination and countries of origin, respectively.
