The ten regions
| Region | States covered | What defines it |
|---|---|---|
| Yucatán Peninsula | Yucatán, Quintana Roo, Campeche | Flat limestone shelf, cenotes, Maya sites, no surface rivers |
| Riviera Maya | Quintana Roo (Caribbean coast) | 130 km of Caribbean resort coast, Cancún to Tulum |
| Baja California Peninsula | Baja California, Baja California Sur | 1,250 km peninsula, desert, whales, Sea of Cortez |
| Pacific Coast | Sinaloa to Chiapas (8 states) | Resort bays, Sierra Madre del Sur falling to the sea |
| Gulf Coast | Tamaulipas, Veracruz, Tabasco, Campeche | Humid lowlands, oil, historic ports |
| Central Mexico | Mexico City, State of Mexico, Morelos, Puebla, Tlaxcala, Hidalgo | High valleys and volcanoes; a third of the population |
| El Bajío | Guanajuato, Querétaro, Aguascalientes, parts of Jalisco | Colonial silver towns, auto and aerospace industry |
| Northern Mexico | Chihuahua, Coahuila, Nuevo León, Sonora, Durango, Tamaulipas | Deserts and ranching; border and industrial cities |
| Southern Mexico | Oaxaca, Chiapas, Guerrero | Mountainous, indigenous, the poorest and most diverse region |
| Sierra Madre | Cross-cutting: about 20 states | The three mountain systems framing the central plateau |
How big each region is
The eight regions built from whole states, largest first. Population is the 2020 INEGI census total for the states listed; area is their combined area, and the last column is the share of Mexico's 1,960,682 km². The Riviera Maya (about 5,800 km²) and the Sierra Madre are not whole-state regions and are left out of the arithmetic.
| Region | States | Population (2020) | Area km² | Share |
|---|---|---|---|---|
| Northern Mexico | 6 | 20,978,307 | 846,142 | 43.2% |
| Pacific Coast | 8 | 31,307,448 | 458,712 | 23.4% |
| Gulf Coast | 4 | 14,921,275 | 234,313 | 12.0% |
| Southern Mexico | 3 | 13,216,661 | 230,664 | 11.8% |
| Baja California Peninsula | 2 | 4,567,467 | 145,359 | 7.4% |
| Yucatán Peninsula | 3 | 5,107,246 | 141,736 | 7.2% |
| Central Mexico | 6 | 39,182,978 | 87,849 | 4.5% |
| El Bajío | 3 | 9,961,008 | 47,914 | 2.4% |
The two extremes are the first and second-to-last rows. Northern Mexico takes 43% of the land and holds 17% of the people; Central Mexico takes 4.5% of the land and holds 31%. Everything about travel in the two — driving distances, bus frequency, how far apart towns are — follows from that difference.
Why regions rather than states?
Travel, climate and history follow geography more than state lines. The Yucatán Peninsula behaves as one unit across three states; Puerto Vallarta shares more with Mazatlán than with Guadalajara. If you are planning a trip or studying the country, start with a region map, then drop down to the state maps for detail.
There is no official answer to how many regions Mexico has. INEGI, the national statistics institute, publishes data by state and municipality and defines no standard regional division. Federal bodies each cut the country their own way for their own purposes: the Bank of Mexico reports the regional economy in four blocks, CONAGUA manages water through 13 hydrological-administrative regions drawn on watersheds, and tourism promotion has used its own circuits and routes. The ten regions here are the ones travellers and guidebooks actually use, and they match the physical map: three mountain systems, two peninsulas, two coastal plains and a high central basin.
Where the regions overlap
Several states sit in two regions at once, which is a feature of the scheme rather than a flaw. Quintana Roo is part of the Yucatán Peninsula as geology and part of the Riviera Maya as a coastline. Tamaulipas belongs to Northern Mexico by border, industry and climate, and to the Gulf Coast by its 420 km of shore. Campeche is peninsular and Gulf at once. Oaxaca, Guerrero and Chiapas appear in both Southern Mexico and the Pacific Coast, and Jalisco straddles the Pacific coast and El Bajío. The Sierra Madre is the one region defined by relief alone, and it crosses every other region on the list, which is why it is mapped separately.
What each zone is like to travel
The north is big, dry and driven: 800,000 km² of desert, sierra and ranch country, with long empty highways between Monterrey, Chihuahua and the border cities, and the Copper Canyon railway as the one classic journey. The two peninsulas are the country's road trips — Highway 1 down 1,250 km of Baja to La Paz and Los Cabos, and the flat run across Yucatán between Mérida and Cancún through cenote country.
The centre is the opposite: short distances, dense bus networks and the highest ground in the country, with Mexico City, Puebla and the volcanoes within a two-hour drive of each other, and the Bajío's silver towns an hour or two further north. The Pacific coast is a 2,200 km string of resort bays on Highway 200, from Mazatlán through Puerto Vallarta and Acapulco to the Oaxacan surf beaches. The Gulf coast is humid, green, industrial and much less visited, with Veracruz the oldest port in the Americas. The south is mountainous and indigenous, slow to cross and the strongest region for craft, food and archaeology.
Season matters more than region for most trips. November to April is dry almost everywhere; June to October is the rainy season inland and the Atlantic hurricane season on the Caribbean and Gulf coasts, which runs 1 June to 30 November. The climate map shows the pattern, and the physical map shows the relief the regions are drawn around.
Questions about the regions of Mexico
What are the main regions of Mexico?
There is no official list. The ten used here are the Yucatán Peninsula, the Riviera Maya, the Baja California Peninsula, the Pacific Coast, the Gulf Coast, Central Mexico, El Bajío, Northern Mexico, Southern Mexico and the Sierra Madre. They follow climate, terrain and travel patterns, so a few states belong to more than one.
Which region is Cancún in?
Cancún is in the state of Quintana Roo, which puts it in two of the regions here: the Yucatán Peninsula, the three-state limestone shelf, and the Riviera Maya, the 130 km of Caribbean coast that starts just south of the city.
What is the Bajío?
The high farming and manufacturing plain north-west of Mexico City, at 1,700–2,000 m, covering Guanajuato, Querétaro, Aguascalientes and parts of Jalisco and Michoacán. It holds the colonial silver towns of Guanajuato and San Miguel de Allende and most of Mexico's car and aerospace plants.
Is the Yucatán Peninsula the same as the Riviera Maya?
No. The peninsula is the whole limestone platform of Yucatán, Quintana Roo and Campeche, about 141,700 km². The Riviera Maya is a strip of it: roughly 130 km of Caribbean shore in Quintana Roo, from Puerto Morelos south to Tulum.
