Since the 2006 High level Dialogue on International Migrationand Development, organized by the United Nations General Assembly, and the creation of the Global Forum on Migration and Development, the issue of international migration has risen on the agenda of policy -makers around the world. The increased demand for policy relevant migration information has exposed serious deficiencies in the availability of basic data on global migration levels, trends and characteristics. Many countries collect data on persons under 20 years of age who were born outside the country of enumeration and who may or may not have the citizenship of that country, usually as part of their population census or through administrative means, and at different intervals. While more information on child and adolescent migrants has become available in the recent past, harmonize destimates for all countries and are as in the world at regular intervals are currently not available. Answers to basic questions, such as "how many children and adolescents are participating in international migration?", "what are the age profiles of those moving across borders?", "do girls and boys have the same propensity to migrate?", and "how does migration affects children and adolescents moving across borders and those who stay behind?" remain elusive. The absence of information on basic migration trends and its impacts on children and adolescents severely hampers one of UNICEF’s main concerns to ensure children's,adolescents’and women’s rights in receiving societies regardless of citizenship and migratory status as well as the endeavors of policymakers at national and regional levels todesign and implement evidence-based policies in order to maximize the positive effects of migration and to minimize its negative effects on migrant families and migrant communities of origin and destination.
