Since 2002, the mayor has been Francisco Álvarez, of the Partido Revolucionario Dominicano (PRD).

[10][11][12] Tamboril is also one of the major agricultural producers in the province, principal crops being plantains, cassava, and sweet potato, which are sold in the markets in Santiago.

Due to the proximity to Santiago, where much of the population obtains health and education, the social services in Tamboril are abbreviated and consist of a health clinic, and two rural polyclinics.
