of −1.5 per thousand. Continual decline has been documented since the census period of 1975–1985, which showed a rate of −5.6 per thousand. The decrease is due in large part to lowered fertility, partly offset by mortality, and to a smaller degree in migration. The birth rate declined by 19% from 1996 (17 per thousand) to 2004 (13.8 per thousand). Similarly, the total fertility rate (TFR) declined from 2.24 in 1996 to 1.79 in 2004. However, mortality continued to fall with life expectancy at birth for both sexes increasing by 1.73 years. In the census of 2011, Montevideo had a population of 1,319,108.

The municipality's first mayor (1909–1911) was Daniel Muñoz. Municipalities were abolished by the Uruguayan Constitution of 1918, effectively restored during the 1933 military coup of Gabriel Terra, and formally restored by the 1934 Constitution. The 1952 Constitution again decided to abolish the municipalities; it came into effect in February 1955. Municipalities were replaced by departmental councils, which consisted of a collegiate executive board with 7 members from Montevideo and 5 from the interior region. However, municipalities were revived under the 1967 Constitution and have operated continuously since that time. Since 1990, Montevideo has been partially decentralized into 18 areas; administration and services for each area is provided by its Zonal Community Center (Centro Comunal Zonal, CCZ), which is subordinate to the Intendancy of Montevideo. The boundaries of the municipal districts of Montevideo were created on 12 July 1993, and successively amended on 19 October 1993, 6 June 1994 and 10 November 1994. In 2010, the city CCZ were abolished and eight municipalities were created instead. The city government of Montevideo performs several functions, including maintaining communications with the public, promoting culture, organizing society, caring for the environment and regulating traffic. The city hall is the Palacio Municipal on 18 de Julio Avenue in the Centro area of Montevideo. The legislative branch of government, the Junta Departamental, or the Congress of Montevideo, governs the Department of Montevideo.
