Since 1987, the city has been divided into 10 administrative districts (‘districtes’ in Catalan, ‘distritos’ in Spanish):
Barcelona
Barcelona is the capital and largest city of the autonomous community of Catalonia, as well as the second most populous municipality of Spain. With a population of 1.6 million within city limits its urban area extends to numerous neighbouring municipalities within the Province of Barcelona and is home to around 4.8 million people.

Districts
The districts are based mostly on historical divisions, and several are former towns annexed by the city of Barcelona in the 18th and 19th centuries that still maintain their own distinct character. Each district has its own council led by a city councillor. The composition of each district council depends on the number of votes each political party had in that district, so a district can be led by a councillor from a different party than the executive council.
