What is mixed migration ?

“Mixed migration refers to complex population movements: people using the same routes and modes of transportation to travel, but moving for different reasons. The main characteristics of mixed migration flows include the multiplicity of factors driving the movement, and the different needs and profiles of the persons involved. These mixed movements may include migrants, some of whom may have specific needs, refugees, unaccompanied and separated children, or victims of trafficking. Some individuals may fall into more than one of these categories. Mixed migration frequently occurs irregularly, without the requisite documentation, and often involves human smuggling and trafficking.”
