The Dominican Republic is divided into 31 provinces (), while the national capital, Santo Domingo, is contained within its own district.
The division of the country into provinces is laid down in the constitution (Title I, Section II, Article 5) and enacted by law. The latter is currently Law 5220 on the Territorial Division of the Dominican Republic (), issued 1959 and frequently amended to create new provinces and lower-level administrative units.
The provinces are the first-level administrative 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 () for each province but not for the Distrito Nacional (Title IX of the constitution).
The provinces are divided into municipalities (), which are the secondâÂÂlevel political and administrative subdivisions of the country.
The Distrito 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 new Santo 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 () and mayor () which are in charge of its administration.
The provinces are also constituencies for the elections to the bicameral National Congress (). Each province elects one member of the Senate () and a guaranteed minimum of two members of the Chamber of Deputies ().
