Languages of Catalonia
The main cause of Spanish and Catalan social bilingualism in modern Catalonia was large-scale migration from the rest of Spain during the 20th century, as Catalonia started a significant industrialization which demanded an increased workforce from elsewhere. Spanish has historically been spoken among a minority of civil servants born in other regions in Spain and among segments of the wealthiest bourgeoisie. Spanish has also been spoken as a second language by most Catalans, as it has been the only official language over long periods since the eighteenth century.
Catalonia
The Parliament of Catalonia (in Catalan: "Parlament de Catalunya") is the legislative body of the Generalitat and represents the citizens of Catalonia. It is elected every four years by universal suffrage, and it has powers to legislate in different matters such as education, health, culture, internal institutional and territorial organization, election and control of the president of the Generalitat and the Government, budget and other affairs, according with the Statute of Autonomy. The last Catalan election was held on 21 December 2017, and its current president is Roger Torrent, incumbent since January 2018.
