Mexico covers roughly 1.96 million square kilometres in the southern part of North America, between the United States to the north and Guatemala and Belize to the southeast. Its western and southern shores face the Pacific Ocean and Gulf of California, while the east opens to the Gulf of Mexico and Caribbean Sea. Mexico City, on the high interior plateau, is the federal capital. The land is organized around the Sierra Madre Occidental and Sierra Madre Oriental, which frame the Mexican Plateau before converging toward the Trans-Mexican Volcanic Belt. Farther south, the Sierra Madre del Sur, Chiapas highlands and low-lying Yucatán Peninsula create sharply different landscapes. Pico de Orizaba, the country’s highest summit, rises above the central volcanic belt, while broad arid basins dominate much of the north. River systems are generally shorter and more seasonal in the dry north than in the humid southeast, where the Grijalva-Usumacinta basin carries much larger flows.
Climate varies as much with elevation and exposure as with latitude. Much of northern and north-central Mexico is arid or semi-arid, with sparse, irregular rainfall and large temperature ranges, while the central highlands are generally milder because many cities stand well above 1,500 metres. Gulf and Caribbean lowlands are warmer and more humid, and southern Pacific and southeastern regions have tropical wet-and-dry or humid climates. Most of the country receives the largest share of its rain in the summer half of the year, although northwestern Baja California has a Mediterranean-type winter-rainfall regime. Tropical cyclones affect both the Pacific and Gulf-Caribbean coasts, causing destructive flooding but also supplying seasonal water. Drought is a recurrent economic risk, particularly across northern and central basins, where large cities, irrigated agriculture and industry place heavy pressure on groundwater. Flooding, heat, wildfire, soil erosion and coastal exposure create different environmental risks elsewhere.
These climatic gradients support deserts and xeric scrub in the north, pine-oak forests across the mountains, cloud forests on humid slopes, tropical dry forests along parts of the Pacific, humid forests in the southeast, and mangroves, wetlands and coral environments on the coasts. Mexico’s position between the Nearctic and Neotropical realms, combined with rugged topography, helps explain its high species richness and endemism. Protected landscapes range from desert reserves and volcanic highlands to the Sian Ka’an wetlands and Calakmul forests. INEGI recorded about 29.8 million hectares of agricultural land in 2022, supporting maize and beans alongside commercial avocado, berries, tomatoes, peppers, livestock and agave. Irrigation is especially important in the drier north and northwest, whereas rain-fed smallholder farming remains widespread in the centre and south. Forests covered about one-third of national land area in 2023, while deforestation, fragmentation and land degradation remain uneven regional concerns.
Human settlement in present-day Mexico reaches back thousands of years, but the societies conventionally grouped within Mesoamerica developed especially complex urban, political and religious systems in the centre and south. Olmec centres on the Gulf lowlands influenced later traditions, while Monte Albán, Teotihuacan and Maya cities became major nodes of trade, ritual and political authority at different periods. Teotihuacan flourished for centuries before its decline in the first millennium CE; later Toltec, Mixtec, Zapotec, Maya and other polities continued to reshape regional power. By the fifteenth century the Mexica, whose capital Tenochtitlan stood in the Basin of Mexico, headed an expansionist tribute empire but did not control all of Mesoamerica. Hernán Cortés reached the mainland in 1519 and allied with Indigenous enemies of the Mexica; after warfare, epidemic disease and siege, Tenochtitlan fell in 1521. Spanish rule then consolidated New Spain, linking silver-mining districts, Indigenous farming communities, Atlantic commerce and the trans-Pacific Manila galleon system. Colonial institutions transformed landholding, religion and political authority while many Indigenous communities preserved distinct local identities.
The crisis of Spanish monarchy helped trigger the insurgency that began in 1810, and independence was consummated in 1821 after eleven years of conflict. The new state struggled to establish stable institutions, finances and territorial control; the nineteenth century brought federalist-centralist disputes, the 1846–1848 war with the United States and loss of vast northern territories, the liberal Reform era, French intervention and the restored republic. Under Porfirio Díaz, especially from the 1880s to 1911, railway building, mining and foreign investment accelerated integration but coincided with concentrated landholding and political exclusion. The Mexican Revolution began in 1910 and produced prolonged regional warfare before the Constitution of 1917 established a durable federal framework and major principles on land, labour and national resources. Post-revolutionary governments built a centralized political order dominated for most of the twentieth century by the Institutional Revolutionary Party. Electoral reforms gradually widened competition, culminating in the opposition presidential victory of 2000. Contemporary Mexico is a federal presidential republic of 31 states and Mexico City, with institutions shaped by both the revolutionary settlement and later democratization.
Mexico has one of Latin America’s largest and most diversified economies, combining a vast domestic market with deep integration into North American manufacturing. Vehicles and parts, electronics, electrical equipment, machinery, medical devices and other manufactures dominate merchandise exports, while oil remains economically and fiscally important without the overwhelming export role it once held. Agriculture is commercially significant in fruit, vegetables, beverages and livestock products; services account for most output and employment, while tourism and remittances are major sources of foreign exchange and household income. INEGI reports that real GDP grew only 0.8% in 2025, a marked slowdown after the post-pandemic expansion. Banco de México recorded about US$62.5 billion in remittance receipts that year. Export-oriented industrial clusters are strongest along the northern border and in the Bajío and central corridor, reinforcing disparities with poorer southern states. Proximity to the United States supports complex cross-border supply chains but also exposes investment and production to U.S. demand, tariff policy and rules of origin.
The 2020 Population and Housing Census counted 126,014,024 residents; a World Bank estimate placed the population at about 130.9 million in 2024, distinguishing the census count from later demographic estimation. National density in 2020 was about 64 people per square kilometre, but settlement is heavily concentrated on the central plateau and in major metropolitan and industrial corridors. INEGI classified 79% of residents as living in urban localities in 2020, compared with 43% in 1950. The Mexico City metropolitan region is the dominant political and financial centre, while Guadalajara, Monterrey, Puebla-Tlaxcala, Tijuana, León and other border and Bajío cities anchor manufacturing, logistics and regional services. Population is much thinner across the deserts of Baja California, Sonora, Chihuahua and Coahuila and in many mountainous southern districts. Federal administration comprises 31 states and Mexico City, below which municipalities—and territorial boroughs in the capital—perform important local functions.
Spanish is the dominant language of government, education, media and commerce, but Mexico is legally pluricultural rather than linguistically homogeneous. The National Institute of Indigenous Languages identifies 68 Indigenous linguistic groupings encompassing 364 recognized variants in 11 language families. The 2020 census counted about 7.36 million people aged three or older who spoke an Indigenous language, with especially strong concentrations in Oaxaca, Chiapas, Yucatán, Veracruz and Puebla; Nahuatl, Maya, Mixtec and Zapotec are among the most widely spoken. Religious affiliation has also diversified: the 2020 census recorded about 78% of the population as Catholic, alongside growing Protestant and evangelical communities and a larger population reporting no religion. Mexican culture reflects Indigenous, European, African, Asian and later migrant influences that vary strongly by region. The muralism of Diego Rivera, José Clemente Orozco and David Alfaro Siqueiros connected art to revolutionary politics, while literature, music, architecture and craft traditions continue to express regional identities and debates over nationhood, class and Indigenous rights.
Transport geography reflects both Mexico’s scale and its trade orientation. SICT reported that the National Road Network extended about 405,092 kilometres in 2025 and railway lines about 29,034 kilometres. Freight rail is especially important for automotive, industrial, agricultural and bulk cargo moving between northern and central production zones, border crossings and ports; passenger rail remains much more limited despite recent expansion projects. Major Pacific gateways include Manzanillo and Lázaro Cárdenas, while Veracruz and Altamira connect the industrial interior to the Gulf and Atlantic. Mexico City, Cancún, Guadalajara, Monterrey and Tijuana are principal aviation nodes. Electricity access reached 99.7% of the population in 2023, although service quality and network resilience vary regionally. The power system combines natural gas, oil products, hydroelectricity, wind, solar, geothermal and nuclear generation, while oil and gas infrastructure remains concentrated around Gulf producing areas and national pipeline networks. The World Bank recorded internet use at about 83% of the population in 2024.
Mexico’s international weight comes from the intersection of geography, industrial capacity, population and diplomacy. It is a member of the G20 and OECD, participates in the Pacific Alliance, and sits at the core of North American production through the United States-Mexico-Canada Agreement. That framework remains in force, but the July 2026 joint review did not produce immediate renewal in its existing form, leaving further negotiations over automobiles, steel, agriculture, labour rules and economic security. This matters because Mexican manufacturing is tightly embedded in U.S.- and Canadian-linked supply chains even as the country seeks stronger domestic value added and broader investment. At home, water stress, uneven productivity, infrastructure gaps, informality, regional inequality and organized-crime violence constrain development; preliminary INEGI data nevertheless showed the national homicide rate falling to 21.4 per 100,000 in 2025 from 25.8 in 2024. Mexico’s medium-term position will depend on whether continental integration produces wider productivity and institutional gains while environmental and security pressures remain manageable.
