Answer:
B) migration flow within Mexico
Step-by-step explanation:
The interregional migration is a migratory pattern that occurs inside a country, or rather from one region of the country to another of its regions. This happens in pretty much every country in the world, where people choose the most attractive places in the country as their future home, as they offer some advantages when it comes to their professional development, finances, higher standard of living. In a country like Mexico, the majority of the interregional migration is between the countryside and the large cities, especially the capital Mexico City. The reason for this is that the people in the rural areas are much more limited in their opportunities and they live in poverty in general, while the large cities are well developed and they offer lot of opportunities for better careers and life.
