Administrative structure of Spain

Autonomous communities, provinces, comarcas, municipalities

In Spain, an autonomous community (C.A.)​ is a territorial entity that, within the Spanish constitutional legal system, is endowed with autonomy, with its own institutions and representatives and certain legislative, executive and administrative powers, which assimilates it in many aspects to federated entities, therefore it could be said that Spain is quasi-federal.

The promulgation of the 1978 Constitution, which includes the right to autonomy of the nationalities and regions that make up the State, represented a 180-degree change with respect to the previous regime, which was based on traditional centralized plans.

After the ratification of the Magna Carta, and as a result of the implementation of the principles contained in Title VIII, in the course of a few years the process of establishing the 16 autonomous communities and the foral community has been completed, through the approval of their Statutes of Autonomy, although only four of them —Catalonia, the Basque Community, Galicia and Andalusia— have been endorsed by their citizens.

However, in practice, the autonomic pacts forced the provinces to form autonomous communities. In fact, it serves as an example that, in March 1983, the only province that was not part of any community, Segovia, was forced by government decree to integrate into Castille y León “for reasons of national interest.”

Spain and its 17 autonomous communities are subdivided into 50 provinces.

Most of the provinces—with the exceptions of Álava, Asturias, Biscay, Cantabria, Gipuzkoa, the Balearic Islands, La Rioja, and Navarre—are named after their principal town. Only two capitals of autonomous communities—Mérida in Extremadura and Santiago de Compostela in Galicia—are not also the capitals of provinces.

Seven of the autonomous communities comprise no more than one province each: Asturias, the Balearic Islands, Cantabria, La Rioja, Madrid, Murcia, and Navarre. These are sometimes referred to as “uniprovincial” communities.

The municipality is the basic local administrative division in Spain together with the province.

Each municipality forms part of a province which in turn forms part or the whole of an autonomous community. There are a total of 8,118 municipalities in Spain, including the autonomous cities of Ceuta and Melilla. In the Principality of Asturias, municipalities are officially named concejos (councils).

In Spain traditionally and historically, some autonomous communities are also divided into comarcas. Some comarcas (in Catalonia or in Aragon) have a clearly defined status, are regulated by law and even their comarcal councils have some power.

In some other cases (La Carballeda) their legal status is not very formal for they correspond to natural areas, like valleys, river basins and mountainous areas, or even to historical regions overlapping different provinces and ancient kingdoms. In such comarcas or natural regions municipalities have resorted to organizing themselves in mancomunidad (commonwealth), like the Taula del Sénia, the only legal formula that has allowed those comarcas to manage their public municipal resources meaningfully.

There is even a comarca, the Cerdanya that is divided between two states, the southwestern half being counted as a comarca of Spain, while the northeastern half is part of France.

In English, a comarca is equivalent to a district, county, area or zone.
