The commune encompasses a large number of villages, hamlets and other rural entities. Its second most populous locality, after San Carlos, is Cachapoal, with 1,164 residents in 2002 (578 male, 586 female). This village has been considered as "urban" in the 2002 census by the National Statistics Institute.

The city was founded by a Spaniard, don José Joaquín del Pino de Rozas y Negrete on July 3, 1800.

On May 15, 1813, San Carlos was the setting for one of the most important battles of the Chilean War of Independence, the Battle of San Carlos, where the patriot army, led by general José Miguel Carrera defeated the royalist army. The outcome of the battle set the ground for the patriot uprising in the whole region.

The city of San Carlos is also the birth city of various artists and famous people including painters, authors, and singers. The painter Hernán Gazmuri was born here. The famous group of singers called Los Angeles Negros (The Black Angels) was also formed here. Although the township of San Fabián argues the birth place of Violeta Parra, she is included amongst Gazmuri and Los Angeles Negros as a famous folklorist, author, investigator, and singer born in San Carlos. The house in which the famous artist was supposedly born is located on the street El Roble # 535-531. This place was declared a National Monument in accordance with the Decree Law Number 668 on September 29, 1992.

Currently the city is working on a new initiative to create the "Casa Museo de Violeta Parra" (House Museum of Violeta Parra). This is a project based on the San Carlos Government’s idea that not only will the Fundación Violeta Parra de Santiago (Foundation Violeta Parra of Santiago) participate, but also specific contacts of the Parra family that have already visited the site in numerous occasions.

Among the city’s attractions lies the Medialuna of San Carlos which is a sports arena where the Chilean rodeo is practiced. The arena has a capacity of 8,000 people; second in size only to the Medialuna of Rancagua. It is fitting to also note that the Chilean rodeo is a very popular sport in this zone.

San Carlos has about 50 elementary schools, 10 of them in the urban area, as well as 6 high schools, 5 of them in the urban area.

According to the 2002 census, 25,141 residents of San Carlos commune aged 15 years or older identified themselves as Catholics, equivalent to 68.51% of the total population, while 22.01% described themselves as Evangelical protestants, 0.59% as Jehovah's Witnesses and 1.35% as Latter-day Saints. About 5.03% of the population identified themselves to be atheist or agnostic, while 3.19% declared to follow other religions.

In 1850, General Sofanor Parra was born in this city, who was a renowned Chilean officer of the cavalry branch of the Chilean Army that stood out in the War of the Pacific.

San Carlos is the birthplace of one of the most widely recognized names in Chilean and Latin American folk music, Violeta Parra. She has long been acclaimed as a great folk artist, author, painter, researcher and singer. The house where this famous artist was born is located in the city of San Carlos. It was declared National Monument by Law Decree 668 on September 29, 1992. San Carlos is also the birthplace of other well-known artists. Among them there are painters such as Hernán Gazmuri and a popular band from the 1970s, Los Ángeles Negros.

As a commune, San Carlos is a third-level administrative division of Chile administered by a municipal council, headed by an alcalde who is directly elected every four years.

Within the electoral divisions of Chile, San Carlos is represented in the Chamber of Deputies by Jorge Sabag (PDC) and Frank Sauerbaum (RN) as part of the 42nd electoral district, together with San Fabián, Ñiquén, San Nicolás, Ninhue, Quirihue, Cobquecura, Treguaco, Portezuelo, Coelemu, Ránquil, Quillón, Bulnes, Cabrero and Yumbel.
