The contemporary scientific literature dedicated to cross-border movements of the population prefers to describe these processes using the terms mobility and movers instead of the traditional migration and migrants. The reset of the conceptual framework and language used to characterize movements of people reflects real transformations in the space of human flows. Noting the extremely small and practically not growing share of the world population involved in classical (long-term) migrations and the decreasing attractiveness of resettlement in other countries for permanent residence, some scholars see in these processes the impending end of “the age of migration.” However, the dynamic development of short-term and multiple movements of human masses may testify to the growing expansion of the phenomenon of “permanent mobility”.
