Cities with this climate include Paranavaí (according with Maack) with some characteristics - "Cfa"(h), transition with a humid climate all year round. Parana is the sixth most populous state in Brazil. Its level of urbanization is 83.5%. The 2005 IBGE survey gave the following breakdown by race for the state: White (Branca) 73.0%, Pardo (mixed) 23.3%, Black (Preta) 2.5%, and Indigenous 1.2%. Parana's white population is primarily descendant of Portuguese, Italian, Polish and Ukrainian immigrants, but many German families also settled in the state. A variation of German known as Paraná-Wolga-Deutsch originated in the area. Initially settled by the Guarani and Kaingang Amerindians, until the 17th century, virtually no European presence existed in Paraná. The number of settlers grew around 1750 and the population was composed of Amerindians, Portuguese, and some Spaniards. African slaves from Angola and Mozambique were also present, but in fewer numbers than in other Brazilian areas, because Paraná was an unexplored region that did not need much slave manpower. As part of the province of São Paulo, immigration grew in the mid-19th century, mostly composed of Italian, German, Polish, Ukrainian, and Japanese peoples. While large numbers of Poles and Ukrainians are present in Paraná, their presence in the rest of Brazil is relatively small, especially Ukrainians. In the early 20th century, two waves of migration to Paraná occurred: one coming from the north, mostly of Portuguese, but also of African and Amerindian origin, and another from southern Brazil to the southwest and west, mostly of Portuguese, Italian, and German origins. In 2013, the Paraná had the fifth largest GDP of Brazil, representing 5.90% of the Brazilian GDP in 2005, against 6.4% in 2003. About 15% of Paraná's GDP comes from agriculture. Another 40% comes from industry and the remaining 45% comes from the tertiary sector. As for its exports, in 2012 the main products exported were soybeans (18.73%), Meat Poultry (10.50%), sugar in Natura (8.09%), Soybean Meal (8.00%) and corn (6.36%). The main economic activities are agriculture (sugarcane, maize, soybeans, coffee, tomato), industry (agribusiness, automotive, and paper) and plant extraction (wood and yerba mate).
