Internal migration in Brazil occurs mainly for economic reasons and ecological disasters. Internal migration involves the movement of people within the same territory, which can be between regions, states or municipalities. It does not affect the total number of inhabitants in a country, but it does change the regions involved in this process. In Brazil, economic factors exert the greatest influence on migratory flows, as the capitalist production model creates privileged areas for industries, forcing people to move from one place to another in search of better living conditions and jobs to meet their basic survival needs.
Some examples of internal migration in Brazil occurred in the 1960s, when the droughts devastated the Northeast of Brazil, leading thousands of people to abandon their homes in the Brazilian hinterland due to the lack of agricultural alternatives and social policies in the region. At the end of the 19th century, northeasterners migrated to the North of Brazil because of the rubber cycle.
In the 1970s, migrants from the Northeast and the South left in search of a better life in the Southeast, Brazil's only industrial center at the time.
