Child migrants

Disaggregating migration data by age is essential for analyzing age dynamics of migrant populations. For child migrants, data disaggregated by age, gender and information on whether children are accompanied by a parent, family member, guardian, sponsor, or not, are particularly important to determine potential levels of vulnerability and protection needs during transit and on arrival. Child migrants are at risk of abuse, trafficking and exploitation, especially if they travel alone and through irregular migration pathways. There are several types of data sources that disaggregate migrant stocks and flows by age, although none can offer precise numbers or a full global picture.

Older persons and migration

It is important to collect, process and report data on older persons in the migration context to improve policy and planning. These endeavors will also support the achievement of ageing-related United Nations Sustainable Development Goals (SDGs), such as protecting the human rights of all people of all ages by “leaving no one behind”, and the commitment to address issues of ageing in the 21st century in the Political Declaration and Madrid International Plan of Action on Ageing. Currently, several migration data sources provide migration data disaggregated by age. Nevertheless, given the extensive attention to help the most vulnerable groups of migrants, namely women and children, data on the older migrant population are only occasionally prepared and used. Collecting and disaggregating migration data by age is not sufficient to tackle the challenges faced by older people in a migration context. Older persons in migration contexts are at risk of being overlooked, which might perpetuate vulnerabilities and inequalities. In addition, there is a lack of data on older persons left behind and their needs.

IOM Data Protection Manual

Data protection continues to be a growing field in the context of international organizations. It is also a necessary consideration at national and regional level given the increased use of advanced technology in migration management, data theft, data loss, and unnecessary or inappropriate use and disclosure of sensitive data. While there exists vast literature on data protection, there is limited guidance on protecting personal data in the context of migration.

Family migration

Family is a major driver of migration. Family migration is the term used to categorize the migration of people who migrate due to new or established family ties, and it encompasses several sub-categories: reunification with a family member who migrated earlier (a person with subsidiary protection is also entitled to (re)unite with family members); family accompanying a principal migrant; marriage between an immigrant and a citizen; marriage between an immigrant and a foreigner living abroad; and international adoptions. In general, data on family migration are sparse and family (re)unification programmes are the predominant means to collect such data. These programmes were developed to ensure the right to a family enshrined in Article 16 of the Universal Declaration on Human Rights. Data on family migration are based on visas and residence permits issued to family members, as well as population registers.

In search of a frame: What to expect when you’re sampling immigrants

  What is known about immigrants’ integration into European society?

Migration data sources

The demands for migration data arising from the 2030 Agenda for Sustainable Development have prompted the international statistical community to review the use of traditional sources for migration data, such as population and housing censuses, household surveys and administrative records. There is also increased interest in looking for alternative sources to enhance the collection and analysis of migration data. The better use and understanding of existing data sources are essential to improve migration management and policy. Information about migration comes from a variety of data sources that have strengths and limitations and can be used to produce different migration statistics.
