Internal Migration The migration by internal population contingents follows a geographical logic of proximity and flows. The population also underwent changes due to the limit of the municipality that normally went until the Santa Catarina border to the south, since the registries was by the area covered by the parish. It is noticed that between 1823 and 1879 of the residents of Ponta Grossa who live in the same country or had origin in some city of Paraná (305 people or 8.9%) or of São Paulo, in a greater number: 462 people (13.5%) Among the Paraná cities that contributed most to the population increase were Castro (for historical and economic reasons), followed by Campo Largo, Palmeira, Lapa, São José dos Pinhais, Curitiba, Itapetininga, Itapeva and Sorocaba. But it was not just the two states that made up the population of the city. Rio Grande do Sul had its participation in consequence of the tropeirismo, mainly with the cities of the north of the state: Passo Fundo, Vacaria and Cruz Alta. Other cities that have emerged along the Way of Viamão as well as Ponta Grossa also appear in the origin of the resident princesinos like Lages in Santa Catarina (6 men and 4 women). In recent history Ponta Grossa has received interstate migrants between 1990 and 2010, as a consequence of the dynamics of flows to the mesoregion centers, as has also been occurring in other attractive urban areas of the state. Immigration Russians, Germans, Poles and Austrians form the largest group of immigrants of the nineteenth and twentieth centuries. By the civil registry in the Sant'Ana Registry, one of the principal of the city, the largest registry of grooms between 1889 and 1920 are from the previous three, which proves the affirmative. They are 257 Poles, 102 Germans and 64 Austrians, with booms in different decades according to the biggest waves of immigrants. Since 1870, Empire politicians have encouraged European immigration to the country, considering their advanced agricultural techniques and seeking to fill areas. Although inhabited, were often surrounded by forests and depopulated regions such as the case of Paraná. Other reasons were the lack of the basic foodstuffs. Most of the population was focused on yerba mate production and there were no more slaves for free labor. Immigrants were brought in with the ideal of being French-style "progress" for the city, based on other large urban centers. Russian-Germans
