In the beginning of the XX century, 12% of the population of Rio Grande do Sul were foreigners, an index much higher than the one of Brazil. This fact resulted from the intense migration to the State by the end of the XIX century. This trend has changed over time, indicating an increase in the number of people born in other Brazilian states.
After 1990 the number of migrants from other Brazilian states was already proportionally higher than the number of foreigners. Data from the Population Census of 2010 indicate a total of 347,036 persons residing in RS who were born in other Brazilian states.
On the other hand, the number of persons born in RS who, from the 1940s on, moved to other Federation Units has also increased. Emigration in the State increased significantly until the 70s, having as main destinations the states of Santa Catarina and Paraná. In the following decades the flow of migrants from RS had as predominant destination Central-West region. In 2010 the Population Census identified 1,066,500 persons born in RS residing in other Brazilian states.
Another important aspect of the state demographic dynamics are inter-regional migrations. Approximately 80% of the state migrants have RS itself as their destination. These movements follow the economic and social dynamics of the State, concentrating the flows in the most dynamic regions.
In absolute terms, the COREDEs which have received more migrants are Metropolitano Delta do Jacuí, Vale do Rio dos Sinos, Serra and Produção. In relative terms, those with the highest balance were regions Litoral, Paranhana-Encosta da Serra, Serra and Vale do Caí. On the other hand, those with the highest rates of rural population were those that lost the most population, with relative highlights for COREDEs Médio Alto Uruguai, Fronteira Noroeste, Missões, Noroeste Colonial, Alto da Serra do Botucaraí and Nordeste, all of them with balances lower than -5%.
However, it should be noted that the loss of population is not homogeneous. Even in regions that lost population, hub municipalities have shown positive growth, although it was lower than that of perimetropolitan regions, which have concentrated a higher number of migrants.

¹ Net Rate of Emigration = (natives of RS residing outside the State, except foreign countries) / Total population of natives of RS, except those residing in another country)*100
² Net Rate of Immigration = (non-natives of the State residing in RS, including foreigners / Total Population of RS)*100
³ Net Rate of Internal Immigration = (non-natives of the State residing in RS, excluding foreigners / Total Population of RS)*100
