Cerdanya

Cerdanya, officially the Autonomous Region of Cerdanya (Región Autónoma de Cerdaña; Comunitat autònoma de Cerdanya) is one of the three cultural macroregions of the Baliscan Confederation and is named after the region of the same name in Arriola. Made up of some of the richest Baliscan regions and containing several major industrial complexes, Cerdanya's regions are often collectively dubbed the "locomotive of Balisca", the macroregion is responsible for 34.4% of the Baliscan GDP. Cerdanya's regions have the highest rankings in Human Development Index (HDI) and GDP per capita, some of the lowest infant mortality rates, the highest life expectancies, and the lowest rates of illiteracy among the autonomous regions of Balisca, being by far, the safest area in the country. The homicide rate is 1.8 per 100 thousand as of 2018, almost 1/3 of the national rate. Cerdanya's regions are collectively richer than Chile, Uruguay, Paraguay and Bolivia combined. If Cerdanya were an independent country, its nominal GDP would be ranked among the top 20 in the world (and the third largest in Latin America), and would have the highest HDI in all of Latin America. The economy of Cerdanya is the most developed in Balisca.

With more than 34 million inhabitants in 2019, the region of Cerdanya is the third most populous of the Baliscan regions (26% of the national population), of which around 14 million live in Greater Concepción-Metropolitian Merced area (commonly known as Mercepción) and 3 million in the rest of the province. Around 23.8% of the inhabitants weren't born in the province, of whom 3,918,552 are immigrants from other provinces and 758,640 were born abroad.

Most of its inhabitants are descendants from colonial-era settlers and immigrants from Europe who arrived within the 19th and 20th centuries, including Italian, Portuguese, Japanese and Aranese Baliscans, though composed mainly of descendants of German and Norwegian immigrants. There is also a large proportion of the population from other regions, especially from Santo Antônio. A number of suburbs in the province are also home to a large, predominantly mestizo population that began migrating from the Balisca's northern provinces in the mid-20th century to take advantage of growing employment opportunities. These same communities are also home to considerable numbers of more recent migrants from Paraguay and Bolivia.
