TheDominican Republic is divided into 31provinces (provincias), while thenational capital,Santo Domingo, is contained withinits own district.
The division of the country into provinces is laid down in the constitution (Title I, Section II, Article 5)[1] and enacted by law. The latter is currently Law 5220 on the Territorial Division of the Dominican Republic (Ley No. 5220 sobre División Territorial de la República Dominicana), issued 1959 and frequently amended to create new provinces and lower-level administrative units.
The provinces are the first-leveladministrative subdivisions of the country. The headquarters of the central government's regional offices are normally found in the capital cities of provinces. The president appoints an administrative governor (Gobernador Civil) for each province but not for the Distrito Nacional (Title IX of the constitution).[1]
The provinces are divided intomunicipalities (municipios), which are the second–level political and administrative subdivisions of the country.[1]
TheDistrito Nacional was created in 1936. Prior to this, the Distrito Nacional was the old Santo Domingo Province, in existence since the country's independence in 1844. It is not to be confused with the newSanto Domingo Province, which split off from it in 2001. While it is similar to a province in many ways, the Distrito Nacional differs in its lack of an administrative governor and consisting only of one municipality,Santo Domingo, the city council (ayuntamiento) and mayor (síndico) which are in charge of its administration.[2]
The provinces are also constituencies for the elections to thebicameralNational Congress (Congreso de la República). Each province elects one member of theSenate (Senado) and a guaranteed minimum of two members of theChamber of Deputies (Cámara de Diputados).[1][3]
The following is a table of the provinces and their capital cities. The population figures are from the 2021 population estimate.[4]
