According to the Survey of the Involvement of the Adult Population in Learning Activities[1] distributed by the National Institute of Statistics with data from 2016, in regards to the languages in Spain that are native languages or languages that are not native but used, 98.9% of the population speaks Spanish, 17.5% speaks Catalan, 6.2% speaks Galician, 5.8% speaks Valencian and 3.0% speaks Basque. For autonomous communities, Catalan can be used by almost 85% of the population of Catalonia and 63.1% of the Balearic region, Galician is used by 89% of Galicians, Valencian is used by 51.8% of the residents in that community and Basque is spoken by 55.1% of the Basque population and 21.7% of people in Navarre. With regard to native languages alone, Galician is the native language of 82.8% of Galicians, Catalan is the native language of 31.6% of people in Catalonia and of 42.9% of the residents in the Balearic region. Valencian (a variety of Catalan) is the native language of 35.2% of the population in that community and Basque is the native language of 33.7% of the Basque people and of 14.6% of those from Navarre.[2]
With the exception of Basque, which is a language isolate, all of the vernacular languages spoken now in Spain are Romance languages, within the family of the Indo-European languages. The majority belong to the sub-group of languages Iberian Romance, with the exception of Catalan/Valencian and Aranese, belonging to the Occitano-Romances and Aragonese. Affiliation between one subgroup or the other is a cause for active discussion.
See main article: Spanish language. Spanish (sometimes called Castilian) is the only official language of the entire country and is spoken habitually and as a native language among a vast majority of the Spanish population. Spain is, along with Colombia[3] and after Mexico and the United States,[4] ranked third in the world as the country with the most Spanish speakers.
Spanish is the only official language in Asturias, Cantabria, La Rioja, Aragon, Castile and León, Madrid, Castilla-La Mancha, Extremadura, Andalusia, the Canary Islands and the region of Murcia, as well as Ceuta, Melilla, and half of Navarre.
It is also co-official with other languages in Catalonia, Balearic Islands, Valencia, Galicia, Basque Country and the Basque zone of Navarre. In all of the bilingual autonomous communities, with the exception of Galicia, Spanish is actually the native language of the majority of the population, although this is due in large part to the internal migration processes that occurred in Spain from the middle of the 20th century.
The predominance of Spanish started in the Middle Ages with the Reconquista, expanding throughout the Kingdom of Castile (in which the language was born) and later to other areas in the Iberian peninsula; it had cultural prestige and was also spoken in part of the Kingdom of Aragon and of the Kingdom of Navarre. It gained importance in becoming an auxiliary language, along with commercial and diplomatic communication, in the 16th and 17th centuries. In the following centuries Spanish continued its expansion at the expense of the languages bordering with it; this is shown clearly in the case of the Leonese and Aragonese languages, and also in the case of Basque. During the second half of the 20th century, Francoism drove the regional languages away from public use and favored the use of Spanish; the internal migrations happening around the same time contributed to the predominance of Spanish too. This situation was reverted with the arrival of democracy in Spain and especially with the passing of the Constitution of 1978 which recognized the co-official status of the regional languages in their respective territories; from then on the bilingual autonomous communities began several different policies to normalize the use of their languages, a situation that had special success in the field of education.
The autonomous communities have established the following official languages in their respective territories: Catalan in Catalonia and the Balearic Islands, Valencian in Valencia, Galician in Galicia, Basque in the Basque Country and a part of Navarre, and the Aranese language in the Aran Valley. Catalan and Valencian are considered two varieties of the same language.
Catalan or Valencian have the recognition of an official language in Catalonia along with Spanish, as well as in the Balearic Islands and the Valencian Community; in Aragon, the Statute of Autonomy defines the language, along with Aragonese, as "one of the manifestations that most stand out of Aragonese history and culture and a social value of respect, coexistence, and understanding". In all of these territories the official name for the language is Catalan, while in Valencia the official name is Valencian.
Additionally, within Spain Catalan is also spoken, though not official, in the easternmost part of Aragon (known as La Franja)[8] and in the region of El Carche, in the northeastern region of Murcia.
In total, Catalan is the language spoken at home by approximately 4,452,000 Spanish citizens.
Galician is co-official in Galicia (Spanish Constitution of 1978 article 3.2 and Statute of Autonomy of Galicia article 5). It also has "respect and protection" in Castile and León, according to article 5.3 of the Organic Law 14/2007, of 30 November, from the reform of the Statute of Autonomy of Castile and León; Galician is spoken in a northwestern corner of that community. Galician belongs, along with Spanish, to the group of Iberian Romance languages, and is closely related to Portuguese, with which it formed linguistic unity (Galician-Portuguese) during the Middle Ages. In fact, according to some Galician and Portuguese authors, they should still be considered a single language today despite the differences that have appeared since the Middle Ages (see Reintegrationism). Galician has three main dialectal areas: western, central, and eastern; those are subdivided into other areas. In addition to Galicia, Galician is spoken in western Asturias and in the westernmost area of the provinces of Leon and Zamora. The Fala of the Valley of Jalama in northwestern Extremadura is related to Portuguese and also to Galician.
In Galicia, Galician is the native language of 40.9% of the population, 30.9% claim Spanish as their native language, and 25.3% have both languages as native; 50.8% of the population habitually use more Galician than Spanish, while 47.8% habitually use Spanish.[9]
As in other autonomous communities, Spanish is the language that is spoken most in urban areas of Galicia, while Galician is spoken in rural areas. In total, Galician is the language spoken at home by approximately 1,302,000 people. Another 563,000 speak Galician interchangeably with Spanish. Unlike in Catalonia, the Valencian Community and the Balearic Islands, in Galicia the main cause of the advance of Spanish over the local language (Galician) is not immigration, but language shift.
Basque is a co-official language with Spanish in the Basque Country and in the northern third of the Foral Community in Navarre. There are six main Basque dialects and a standard variety, Standard Basque.
Basque is spoken altogether by almost one million Spanish citizens (2.15% of the population).
Aranese, a variety of Occitan/Gascon spoken in the Aran Valley, in the northwest of Lleida province, is official in this valley and from 2006 in all of Catalonia following the new Statute of Autonomy. In the Aran Valley, Spanish is the native language of 38.8% of the population (many of them born elsewhere), Aranese is the native language of 34.2% and Catalan of 19.4%, according to the data from the census in 2001.[12] Aranese is the native language of about 2,800 people, representing 0.007% of the population of Spain.
In addition to the official languages, some languages in Spain enjoy status as "protected languages."[13] In contrast to the co-official languages, a protected language
While protected languages may be available as electives, they are not required in any schools, as are the co-official languages. Additionally, protected languages are not used as the vehicular language in any region. The status of protected languages is often debated, and, there are movements to promote Aragonese and Asturian from protected to co-official status.[14]
Aragonese is a romance language spoken by 25,556 native speakers (56,235 including passive speakers) according to a 2011 study.[15]
As of 2023, Aragonese is offered as a subject in about 30 schools of the Aragon region, with around 1,300 students.[16] Limited Aragonese-language television content is available on the regional public broadcaster, with shows such as A Escampar la Boira or Charrín Charrán. Aragonese is protected by the government of Aragon
Asturian language is spoken by 100,000 native speakers (400,000 including pasive speakers)[17] in the region of Asturias.
Limited Asturian-language broadcasting is available on RTPA, and the language is learned as an optional subject by a 53% of primary education students.[18] There is a prominent movement demanding for the declaration of Asturian as an official language in Asturias, which is a matter of an ongoing political debate.[19] At this moment Asturian is a protected language,[20] but could be co-official soon.[21]
The Astur-leonese variant known as leonese is spoken in the Castile and Leon region, where it has protection.
