markedly since 1989 due to rapid urbanization and real estate speculation that generated the "lack" of land (20% were idle). In all, there were 58,730 people living in precarious conditions in 2004. Often residing near urban arroyos sand with buildings in places that should be areas of preservation and inefficient policies for transfer or denial of relocation. By 2040 the population may reach 460 thousand inhabitants, an increase of 31% in relation to that registered in 2019, 3.4% above the national average and 11% of the predicted state average. Race and Color According to the archives of the region (now state) of São Paulo in 1824 there were 75.1% of whites, together with a small share of pardos (4.8%) and free Afro-Brazilians (0.1%), reaching 80%. Historical data of the Sant'Ann Parish exposes 92.52% whites, with only 6.66% of pardos and 0.82% of Afro-Brazilians. The number of natives was not evaluated. For the same year, 76.52% of Afro-Brazilians and 23.48% of pardos were among slaves. But due to the purchase and sale it is possible to change the values. It is from 1832 that in the maps the natives begin to appear, oscillating to less than 1%. Due to the history of European colonization and slavery not so present as in other regions, even in Paraná, the population is predominantly white. The black population declared is smaller than cities with lower population size such as Cascavel, Foz do Iguaçu and São José dos Pinhais. At the same time the number of whites is lower in these cities, but in relation to "Princess of the Fields" is proportional to their fourth place by total number of people. The indigenous population is larger than Maringá, which has a larger population, and Ponta Grossa is behind only the two largest cities in the state. The yellow population is the smallest in proportion to the number of inhabitants in front of the five largest cities of Paraná, with values closer to cities between 100 thousand and 200 thousand inhabitants, being surpassed by some cities of Paraná, especially in the north of the state. The self-reported white population is higher in the center (91.3%) and the lowest in the south of the city: Cará-Cará (72.6%). The black population has greater expression in Santa Cruz and Sutil, between the limits of Ponta Grossa and Palmeira where they are quilombola refugees, coming from the coast and first plateau.
