Guerrero is a state in southern Mexico that is divided into 85 municipalities. According to the 2020 INEGI census, Guerrero is the 13th most populous state with 3,540,685 inhabitants and the 14th largest by land area spanning 63,803.42 square kilometres (24,634.64 sq mi).
Municipalities in Guerrero are administratively autonomous of the state according to the 115th article of the 1917 Constitution. Every three years, citizens elect a municipal president (Spanish: presidente municipal) by a plurality voting system who heads a concurrently elected municipal council (ayuntamiento) responsible for providing all the public services for their constituents. The municipal council consists of a variable number of trustees and councillors (regidores y síndicos). Municipalities are responsible for public services (such as water and sewerage), street lighting, public safety, traffic, and the maintenance of public parks, gardens and cemeteries. They may also assist the state and federal governments in education, emergency fire and medical services, environmental protection and maintenance of monuments and historical landmarks. Since 1984, they have had the power to collect property taxes and user fees, although more funds are obtained from the state and federal governments than from their own income.
