This is an inland valley between the cities of Concepción and Los Angeles, and it felt the greatest impact of the earthquake of 27 February 2010. The Department of Rere was a vital settlement area of Chileans and the three-hundred-year struggle (until the 1870s) to defeat the strong indigenous tribe of the Mapuches.
Chilean settlers of Spanish California from the present Region of the Bio Bío (especially from Concepción, Talcahuano, Los Angeles, Santa Barbara, and the Department of Rere) may have played a part in the establishment of Los Angeles and the rest of southern California in the period between 1775 and 1820.[citation needed]
According to data from the 2017 census, the Region of the Biobío, with 2,018,803 inhabitants, is the second most populous region of Chile, after the Metropolitan Region of Santiago.

Taking into account their 37062.6 km ² in area, was in 2002, a density of 50.23 inhabitants per km2, the third highest nationally.
The 2002 census showed an urban population of 1,528,306 inhabitants, corresponding to 82.1% of regional population and a rural population of 333,256 inhabitants, equivalent to 17.9% of the population of the region. Of the 1,861,562 inhabitants of the region of Biobío in 2002, 915,200 (49.16%) were men and 946,362 (50.84%) were women.
The metropolitan area of Concepción is one of the most populated conurbations in the country with a population of 979,937 inhabitants, corresponding to the sum of the population of the ten districts of Greater Concepción: Concepción (216,061 inhabitants) Talcahuano (250,348), Hualpén (88,046), San Pedro de la Paz (80,447) Chiguayante (81,302) Colonel (95,528) Lota (49,089) Penco (46,016) Tomé (52,440) and Hualqui (20,660).

Along with Araucania, Ñuble, Maule and O'Higgins regions, Biobío's population is believed to be a remarkably homogeneous culture, but is of various ethnic and racial backgrounds. About 70% of inhabitants are of European origin, primarily of Spanish, German, French and other European communities. The mestizos make up 27% of the population and are the result of mixing between Europeans and Amerindians, while Amerindian population is 3%, mainly Mapuche. There is a romantic symbol of Chilenidad: huaso or cowboy/ shepherd "culture", typical of Chile.
According to a 2002 census 58.63% of the inhabitants of the Biobío Region profess Catholicism, equivalent to 805,517 people, the third largest concentration of Catholics in a region in Chile, while the lowest percentage of Catholics corresponding to a region nationwide. 28.36% declare themselves as Protestant or Evangelical, equivalent to 389,632 people, the second largest concentration of Protestants in a region, while the highest percentage of Evangelicals corresponding to a region nationwide.
The province of Arauco is the only province to national level in which the number of Evangelicals, corresponding to 47.47% of the population, is greater than that of Catholics, corresponding to 36.33% of the population. It is a result of Protestant (Lutheran and Calvinist), Jehovah's Witnesses, Seventh-day Adventist and Mormon missionary work in Arauco during the 20th century.
Biobío tends to show a more culturally conservative attitude in contrast to the urban areas of Santiago/Valparaiso, which have a more liberal cosmopolitan position. It is more common for residents to attend church regularly, be it Catholic or Protestant.
Economy
For decades, the characteristic feature of the Biobío Region has been its manufacturing industry, which contributes 35.6% of its GDP and operates mainly around the ports of Talcahuano, San Vicente, Lirquén, and Coronel, the greatest concentration of ports in Chile. The range of activities is broad, extending from iron and steel making to foodstuffs manufacture, petrochemicals, metalworking, oil refining, and shipyards.
The region's dynamism is also rooted in its large rivers. The important hydroelectric power complex on the Laja River is composed of the El Toro, Abanico, and Antuco power plants, and the Pangue and Ralco plants on the upper Biobío River. These facilities supply 26.6% of the energy used from Taltal in the north to Chiloé Archipelago 2,500 km (1,553 mi) to the south.
The region contains almost 44% of Chile's forest plantations, of which around 82% are radiata pine. It is the largest exporter of forestry products and supplies raw materials for pulp and paper plants, sawmills, and related activities.
The fishing industry is another dynamic sector. The region possesses 32% of the country's total fishing fleet, while approximately 50% of the national catch is unloaded at its ports. Moreover, this region alone is responsible for 4% of the world's catch of seafood. Main items include shellfish and conger eel, sardines, anchovy, mackerel, hake, mollusks, crustaceans, and algae.
High-quality fertile soils support a wide variety of crops, principally produce, grains, vegetables, artificial and improved pastures.
Animal husbandry focuses on production of beef, milk, and dairy products. Mining activity includes non-metallic minerals, principally quartz for the glass and steel industries.
