Central America, geographic region of the Americas, comprising Panama, Costa Rica, Nicaragua, Honduras, El Salvador, Guatemala, and Belize. Some geologists and physical geographers extend the northern boundary to the Isthmus of Tehuantepec in Mexico.
This article covers the history of the area from prehistoric and pre-Columbian times to the present. Additional information on the region’s physical and human geography can be found in articles on the individual countries of the region (see Belize; Guatemala; El Salvador; Honduras; Nicaragua; Costa Rica; and Panama). Area 201,594 square miles (522,129 square km). Pop. (2025 est.) 50,510,000.
Geography and climate
Central America makes up most of the tapering isthmus that separates the Pacific Ocean, to the west, from the Caribbean Sea. It extends in an arc roughly 1,140 miles (1,835 km) long from the northwest to the southeast. At its narrowest point the isthmus is only about 30 miles (50 km) wide, and there is no location in Central America that is more distant than 125 miles (200 km) from the sea.
Humid swamps and lowlands extend along both the west and east coasts, but four-fifths of Central America is either hilly or mountainous. The western band of Pacific coastal lowland is narrow and overshadowed by mountain ranges, and, except in Nicaragua and Honduras, the eastern plains along the Caribbean are also narrow. Elevation steadily increases west of the Caribbean lowlands, until, toward the Pacific Coast, plateau highlands culminate in mountain ridges and some 40 volcanic cones, some of which attain elevations of more than 12,000 feet (3,700 meters). Some of Central America’s volcanoes erupt violently from time to time, and earthquakes frequently occur in the region. The weathered volcanic lavas produce a fertile soil, however, and the highlands of the volcanic zones have consequently become highly productive agricultural zones and areas of dense population.
The climates of Central America are essentially tropical, tempered by proximity to the sea, by elevation, by latitude, and by local topography; in consequence, they may vary substantially over short distances. Elevation mitigates the climatic effects of Central America’s tropical latitude so that average temperatures in the highlands are much lower than those in the coastal lowlands. Rainfall is concentrated in a distinct rainy (wet) season, generally from May to November, followed by a drier season from December to April. In general, the Caribbean side receives about twice as much rain as the Pacific region.
Plants and animals
Central America’s natural vegetation is varied. Tropical rainforests occupy the eastern lowlands, while evergreen forests clothe the lower slopes along the Pacific coast, and pine and oak forests grow at somewhat higher elevations. Much of Central America’s timberland, however, has been cleared by slash-and-burn cultivators, who move on when the soil is exhausted. This extensive form of cultivation has become less sustainable as fallow periods are shortened in response to rising demographic pressures and as the forest soils lose their ability to recuperate. Central American forests support comparatively fewer large mammals than those of some other tropical regions but are rich in reptiles and exceptionally diverse in birds and insects. Monkeys, tree frogs, iguanas, and snakes are widespread.
Demographics of Central America
The region can be broadly divided into a more sparsely populated Caribbean lowland zone and a more densely populated Pacific coastal slope, separated by a chain of highland regions that contain many of the largest urban centers. Population growth in Central America has historically been high, though social indicators vary widely across the region. Countries such as Costa Rica and Panama generally exhibit high life expectancy and low infant mortality, though other countries, including El Salvador and Nicaragua, have made significant gains in recent decades. Differences persist, however, reflecting variations in health care systems, infrastructure, and levels of inequality. Spanish is the dominant language of Central America and the official language in six of the countries; English is the lingua franca of much of the Caribbean coast and the official language of Belize. Many Indigenous languages are also spoken throughout the region.

Roman Catholicism has historically been the dominant religion in Central America, though its share of the population has declined in recent decades. Protestant churches, especially Evangelical ones, have grown rapidly since the late 20th century, and Catholics no longer constitute a majority in several countries; in some, including Honduras, Protestants may now outnumber them. In some rural areas, particularly among Indigenous communities, traditional beliefs and practices coexist with Christian traditions.
Most Central Americans identify as of mixed ancestry, reflecting the region’s colonial history. During the colonial period, immigration from Spain predominated, shaping the region’s linguistic and cultural development. Today people of mixed Indigenous and European descent (often referred to as mestizos, or ladinos in Guatemala) make up a majority of the population in many countries. Significant Indigenous populations remain, particularly in Guatemala, where Maya peoples constitute a large share of the population, as well as in parts of Honduras and El Salvador; in Belize, Indigenous groups also form an important minority. Smaller populations include people of African descent and communities descended from more recent immigrants, including those from Asia and the Caribbean.
Economy and development
From the mid-19th century Central America’s economy was based largely on the production of coffee and bananas for export. Cotton, sugar, and beef were exported in increasing amounts after World War II. Corn (maize), beans, and squash traditionally have been grown as staple foods. Vigorous economic growth during the 1960s and ’70s was followed by national indebtedness and economic stagnation in the 1980s. Throughout the 1980s and into the ’90s, armed conflict, civil wars, high inflation, and poor social conditions contributed to economic decline, and most countries had to seek foreign aid from the World Bank or the International Monetary Fund. The civil unrest of the 1980s displaced up to 1,000,000 people, including an estimated 500,000 Salvadorans who entered the United States. Tens of thousands of others migrated to Mexico, Guatemala, Honduras, and other countries in the region. By the late 20th century, the region’s economies began to recover, aided by privatization, trade liberalization, and the expansion of free-trade zones. Manufacturing, particularly in export-oriented assembly plants (maquiladoras), grew, and governments promoted diversification into nontraditional exports.
Economic diversification in Central America has not always produced a more equitable distribution of wealth, and inequality remains pronounced across the region. Much economic activity takes place in the informal sector, where employment is often unstable and lacks social protections, limiting income mobility for large segments of the population. Although manufacturing and service industries have expanded, their benefits have been unevenly distributed. Agriculture continues to provide livelihoods for many, particularly in rural areas where poverty remains higher, and growth in tourism and other services has often been concentrated in specific locations. Remittances (money sent home by migrants working abroad) constitute a major source of income in several Central American countries; in El Salvador, Nicaragua, and Honduras, for example, they account for a substantial share of gross domestic product and play a critical role in household economies.
El Salvador and Panama use the U.S. dollar as their official currency. The principal trading partners outside the region include the United States, Canada, China, and the European Union. Since the 2000s El Salvador, Honduras, Guatemala, Nicaragua, and Costa Rica have participated in the Central America–Dominican Republic Free Trade Agreement (CAFTA-DR), which has further integrated the region into global markets.
