There is a variety of reasons, types, and forms of migration. People move in search of better economic opportunities, some to study and others do it to escape conflicts or due to environmental factors. They may do it as individuals or in groups. Most humans migrate internally, meaning within a single country. External migration means leaving one country to move to another.

There are several types of migration and the most common are:

  1. Labor migration in 2019 there were more than 169 million international migrant workers in the world.
  2. Forced migration or displacement, by the end of 2020, 55 million people were living in internal displacement as a result of conflicts as well as disasters. 
  3. Human trafficking and modern slavery the 2017 report estimates that 40 million people were victims of modern slavery on any given day in 2016.
  4. Environmental migration around 7 million people in 104 countries and territories were living in displacement as a result of disasters that happened not only in 2019 but also in previous years.

The 2030 Agenda for Sustainable Development and its Goals, acknowledges the contribution of migration to sustainable development. The agenda’s core principle is to ”leave no one behind”, including migrants.
