Since the 1970s, international migration to Italy has accentuated the economic and social differences between the North and South of the country. The prevalence of informal jobs, the instability of work, the lack of social mobility have caused many parts of Southern Italy to become areas of "temporary presence" or area of "transition", at least initially, for most of immigrants. This was the role both of immigrants with short-term migratory plans and those who considered their arrival in Southern regions as merely an intermediate stage in a long-term migratory strategy towards the final destination in the Central and Northern regions of Italy; these regions had a high demand for registered migrant workers and therefore offered the prospect of job stability. The migration of regularised migrants from the South to the North of Italy has continued unabated over the years and represents a sort of "migration within the migratory process". However, an opposing trend has emerged in the last years due to the economic crisis, especially among those who have lost their jobs, especially from small and medium-sized enterprises in the area known as the "Third Italy" (Central/North-Eastern Italy) and the main industrial cities (especially Turin). The economic crisis - which has had more immediate and direct consequences in the areas of Central-northern Italy, the destinations of internal migration - has led to increased internal mobility. Migration is now taking place from the North to the South where the possibility of doing irregularly temporary work has re-emerged as a decisive factor.
