Municipalities (Spanish:Municipios) are the administrative divisions under thestates ofMexico according to theconstitution. Municipalities are considered as the second-level administrative divisions by thefederal government. However, some state regulations have designedintrastate regions to administer their own municipalities. Municipalities are further divided intolocalities in the structural hierarchy ofadministrative divisions of Mexico. As of December 2024, there are 2,462 municipalities in Mexico.[1]
In Mexico, municipalities should not be confused with cities (Spanish:ciudades). Cities arelocality-level divisions that are administered by the municipality, although somelarger cities are consolidated with its own municipality and form a single level of governance. In addition, the 16boroughs ofMexico City are considered municipality equivalent, this makes the total number of municipality-level divisions to be 2,478.
The internal political organization and their responsibilities are outlined in the 115th article of the1917 Constitution[2] and detailed in the constitutions of the states to which they belong.Municipalities are distinct fromcities, a form of Mexicanlocality, and are divided intocolonias (neighborhoods); some municipalities can be as large as full states, while cities can be measured in basic geostatistical areas orcity blocks.
All Mexican states are divided into municipalities. Each municipality is autonomous; citizens elect amunicipal president (Spanish:presidente municipal) who heads amunicipal council (Spanish:ayuntamiento), responsible for providing all the public services for their constituents. This concept, which originated after theMexican Revolution, is known as amunicipio libre (free municipality).
The municipal president is elected byfirst-past-the-post voting system for a three-year term and cannot be reelected for the next immediate term. The municipal council consists of acabildo (chairman) with asíndico and severalregidores (trustees).
If the municipality covers a large area and contains more than one city or town (collectively calledlocalidades), one city or town is selected as acabecera municipal (head city, seat of the municipal government) while the rest elect representatives to apresidencia auxiliar orjunta auxiliar (auxiliary presidency or council). In that sense, a municipality in Mexico is roughly equivalent to thecounties of theUnited States, whereas the auxiliary presidency is equivalent to a township. Nonetheless, auxiliary presidencies are not considered a third-level administrative division since they depend fiscally on the municipalities in which they are located.
North-western and south-eastern states are divided into small numbers of large municipalities (e.g.Baja California is divided into only seven municipalities), and therefore they cover large areas incorporating several separated cities or towns that do not necessarily conform to one single conurbation. Central and southern states, on the other hand, are divided into many small municipalities (e.g.Oaxaca is divided into 570 municipalities), and therefore large urban areas usually extend over several municipalities which form one single conurbation. Although an urban area might cover an entire municipality, auxiliary councils might still be used for administrative purposes.
Municipalities are responsible for public services (such as water and sewerage), street lighting, public safety, traffic, supervision of slaughterhouses and the cleaning and 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 1983, they can collect property taxes and user fees, although more funds are obtained from the state and federal governments than from their own collection efforts.
Some municipalities in Mexico are subdivided into internal, third-level administrative organizations. Allmunicipalities of Baja California are subdivided into boroughs, ordelegaciones.Mexicali municipality, for example, is divided into 14 boroughs besides theCity of Mexicali, which comprises the municipal seat and three additional metropolitan boroughs.[3]Querétaro municipality is subdivided into seven boroughs.[4] Nonetheless, the heads of government of the boroughs are not elected by the residents but rather appointed by the municipal president.
Mexico City is a special case in that it is not organized into municipalities. As a result of the Political Reforms enacted in 2016, it is no longer designated as a Federal District and became a city, a member entity of the Mexican federation, seat of the Powers of the Union and the capital of Mexico.[5] Mexico City is divided in16 boroughs, officially calleddemarcaciones territoriales, substituting the olddelegaciones. The boroughs are considered as third-level territorial divisions for statistical data collection and cross-country comparisons.
According to Mexico'sNational Institute of Statistics and Geography, there are in total 2,462 municipalities under the 31states of Mexico as of December 2024.[6] Consider also the 16boroughs ofMexico City, the total number of municipality-level divisions to be 2,478.
Since the Conquest and colonization of Mexico, the municipality became the basic entity of the administrative organization ofNew Spain and theSpanish Empire. The first city council in Mexico was established byHernán Cortés in 1519 inVeracruz; it was also the first in the American mainland.[7] Settlements located in strategic locations received the status ofciudad (the highest status within the Empire, superior to that ofvillas andpueblos) and were entitled to form anayuntamiento or municipality. During the first decades, the local authorities had full powers on the public and economic administration of each municipality, but successive reforms diminished their attributions.[8]
After Independence, the1824 Constitution did not specify any regulation for the municipalities, whose structure and responsibilities were to be outlined in the constitution of each state of the federation. As such, every state set its own requirements for a settlement to become a municipality (usually based on population).
The Constitution of 1917 abolished thejefatura política ("political authority"), the intermediate administrative authority between the states and converted all existing municipalities intomunicipios libres ("free municipalities"), that is, gave them full autonomy to manage local affairs, while at the same time restricting the scope of their competencies.[9] However, in 1983 the 115th article was modified to expand the municipalities' authority to raise revenue (through property taxes and other local services) and to formulate budgets.
Since the 2015 Intercensal Survey, the following municipalities have been created by the state governments.
