Mexico is a federation of 32 autonomous entities, but not all are equal

In short: While Mexico is a federal republic of 31 states and one capital, the structure is more complex than it appears. From the revolutionary concept of the free municipality to the unique status of Mexico City, the nation balances local autonomy with federal oversight through a layered, constitutional hierarchy.

The United Mexican States is composed of 32 federative entities. Under the Constitution of Mexico, the 31 states are free and sovereign regarding their internal affairs, each maintaining its own constitution, unicameral congress, and Superior Court of Justice. This autonomy allows states to govern themselves, provided they do not contradict federal law or form unauthorized alliances with other nations.

Mexico City occupies a distinct position. Originally the Federal District, it served as the capital without belonging to any specific state. Following a 2016 constitutional reform, it transitioned into a fully autonomous entity on par with the states, adopting its own constitution. Unlike other states, however, it receives specific federal funding for health and education. Its internal administration is divided into 16 boroughs, or alcaldías, which are led by elected mayors.

Beneath the state level, the country is organized into 2,460 municipalities. These units are rooted in the concept of the free municipality, a legacy of the Mexican Revolution. Each municipality is autonomous, electing its own administration every three years to manage local utilities. While some states further organize these municipalities into administrative regions or districts to improve governance, these groupings are not constitutional requirements.

The federal government maintains a broader view of these divisions through the National Institute of Statistics and Geography, which classifies smaller settlements as localities, such as cities, towns, or villages. This hierarchy ensures that while states hold significant sovereign power, the administration of territory remains deeply connected to local representation and specific constitutional protections for both municipalities and boroughs.
