Introduction
The Caribbean is a region of more than 7,000 islands, islets, reefs, and cays scattered across the Caribbean Sea — a 2,754,000 km² semi-enclosed body of water bordered by Central America to the west, the Greater Antilles (Cuba, Jamaica, Hispaniola, Puerto Rico) to the north, the Lesser Antilles volcanic arc to the east, and Venezuela and Colombia to the south. Total land area of the islands is just 239,681 km² — about the size of Romania — but the region's combined exclusive economic zone covers most of the Caribbean Sea. About 44 million people live across the Caribbean's 13 sovereign nations and 20+ dependent territories, with three quarters concentrated in the four large islands of the Greater Antilles. Tectonically, the region sits on the Caribbean Plate, a small but seismically active oceanic plate that produces both the Lesser Antilles' chain of active volcanoes (where the Atlantic Plate subducts beneath it) and the deepest point in the Atlantic Ocean — the Puerto Rico Trench at 8,376 m below sea level. Climatically, the Caribbean is in the Atlantic hurricane belt and has been the most hurricane-affected region on Earth for as long as such records have been kept.
Physical Geography
The Caribbean islands fall into two distinct groups separated by tectonic origin. The Greater Antilles (Cuba, Hispaniola — divided between Haiti and the Dominican Republic — Jamaica, Puerto Rico, and the Cayman Islands) make up about 90% of the region's land area and were formed primarily by ancient continental crust, with extensive limestone karst landscapes, fertile alluvial plains, and major mountain ranges including the Sierra Maestra of Cuba (Pico Turquino, 1,974 m), the Blue Mountains of Jamaica (Blue Mountain Peak, 2,256 m), and the Cordillera Central of Hispaniola (Pico Duarte, 3,098 m — the highest point in the entire Caribbean). The Lesser Antilles, running south from Anguilla through Dominica, Martinique, St. Vincent, and Grenada, are a volcanic island arc — the surface expression of where the South American and Atlantic Plates are subducting beneath the Caribbean Plate. Active volcanoes in the chain include Soufrière Hills on Montserrat (which has been continuously erupting since 1995, burying the former capital Plymouth), La Grande Soufrière on Guadeloupe (1,467 m), La Soufrière on St. Vincent (which last erupted in April 2021), and Mount Pelée on Martinique (which destroyed Saint-Pierre in 1902, killing nearly 30,000 people). The Bahamas archipelago, north of Cuba, is geologically distinct — formed by carbonate platforms with no volcanism. The Puerto Rico Trench, north of Puerto Rico, plunges to 8,376 m — making it the deepest point in the Atlantic Ocean.
Climate & Weather
Caribbean climate is tropical maritime almost throughout, with year-round temperatures averaging 24–30°C and minimal seasonal variation. The Caribbean lies between roughly 10°N and 25°N latitude, well within the tropics, and is bathed by the Caribbean Current — a warm westward flow that carries Atlantic surface water through the islands and into the Gulf of Mexico via the Yucatán Channel. Northeasterly trade winds blow steadily across the region year-round. Rainfall varies enormously: from under 500 mm/year on arid leeward islands like Aruba, Bonaire, and Curaçao (in the Caribbean rain shadow of the eastern South American mountains) to over 5,000 mm/year on the windward slopes of mountainous islands like Dominica and St. Lucia. The defining climatic phenomenon is the Atlantic hurricane season, June through November, with peak activity in August–October. The Caribbean averages about 12 named storms per year, of which roughly 6 reach hurricane strength. Major hurricanes (Category 3+) strike specific islands every few years on average; some recent catastrophic examples include Hurricane Maria (2017, devastating Puerto Rico and Dominica), Hurricane Irma (2017, the most powerful Atlantic hurricane ever recorded at landfall), and Hurricane Beryl (2024, the earliest Category 5 hurricane on record).
Natural Resources & Environment
The Caribbean's economic geography reflects unequal natural endowment. Trinidad and Tobago has substantial petroleum and natural gas reserves and is a major LNG exporter, with Pitch Lake — the world's largest natural deposit of asphalt at 40 hectares — also lying on Trinidad. Jamaica is the world's fifth-largest bauxite producer and the largest in the Western Hemisphere; mining the alumina-rich red soils that overlie the limestone karst has dominated Jamaican exports since the 1950s. Cuba is the world's sixth-largest nickel producer and has cobalt and copper resources; sugar cane, tobacco, and citrus dominate Cuban agriculture. The Dominican Republic produces gold and silver (Pueblo Viejo is one of the largest gold mines in the Americas) and has world-class agriculture in cocoa, sugar, and coffee. Tourism is the dominant economic sector across most of the eastern Caribbean smaller islands. The Caribbean is also one of the world's 36 biodiversity hotspots — defined by 11,000+ plant species with 72% endemism — though much of the original tropical forest cover has been lost. Coral reefs ring most islands and support fisheries plus a major dive-tourism economy; about 25% of Caribbean reefs have been lost since the 1970s due to bleaching, ocean warming, and disease.
Human Geography
The Caribbean's 44 million people are distributed across vastly different sized states. Cuba (11 million), the Dominican Republic (11 million), and Haiti (11 million) together hold roughly 75% of the region's population on Hispaniola and Cuba alone. Jamaica (2.8 million), Puerto Rico (3.2 million; a US territory), and Trinidad and Tobago (1.4 million) are the other large polities. The remaining ~25 islands and dependencies range from Barbados (280,000) and the Bahamas (400,000) down to islands of just a few thousand inhabitants. Major urban centers include Havana (2.1 million; one of the great Spanish colonial cities of the New World), Santo Domingo (3.4 million; the oldest continuously inhabited European-founded city in the Americas, founded 1496), Port-au-Prince (1.2 million; Haiti's capital, devastated by the 2010 earthquake), San Juan (2.4 million metro), Kingston (660,000), Port of Spain, Nassau, Bridgetown, and Fort-de-France. Linguistically the region splits into English-speaking, Spanish-speaking (the largest by population, anchored in Cuba, the DR, and Puerto Rico), French-speaking and Haitian Creole, and Dutch-speaking blocs reflecting different colonial histories.
Economy & Industry
Caribbean GDP totals around $300 billion (2024), unequally distributed: the Dominican Republic alone produces about $115 billion, Cuba around $100 billion (varying with exchange rate methodology), and Trinidad and Tobago around $30 billion. Tourism is the dominant export industry across most islands; the cruise sector visits ports of call across the region with very high passenger volumes (about 30 million cruise passengers annually pre-pandemic). Petroleum and natural gas (Trinidad), bauxite/alumina (Jamaica, Suriname, Guyana adjacent to the Caribbean), and offshore financial services (Cayman Islands, BVI, Bahamas) round out the major sectors. Remittances from Caribbean diasporas (especially in the United States, Canada, and the United Kingdom) are a significant share of GDP for most island states.
Notable Landmarks
Caribbean landmarks span natural and cultural geography. Natural: the Pitch Lake in Trinidad (the world's largest natural asphalt deposit); the Boiling Lake in Dominica (the world's second-largest boiling lake); the Pitons of St. Lucia (UNESCO World Heritage twin volcanic peaks); the Cockpit Country karst landscape in Jamaica; Old Havana (UNESCO World Heritage colonial cityscape); Soufrière Hills volcano on Montserrat (active since 1995). Historical: Old San Juan and the El Morro fortress complex (UNESCO); the Citadelle Laferrière atop a Haitian mountain (UNESCO; the largest fortress in the Americas, built 1805–1820 after Haitian independence); Trinidad's historic center (UNESCO, Cuba); Brimstone Hill Fortress on St. Kitts (UNESCO).
Geography & Culture
The Caribbean's culture reflects 500 years of contact and colonialism: Indigenous Taino, Carib, and Arawak populations were largely eradicated by European disease and conquest in the 16th century; the trans-Atlantic slave trade brought millions of West and Central Africans (an estimated 5+ million people, or roughly 40% of total Atlantic slave trade arrivals); subsequent indentured-labor migrations brought South Asian Indians (especially to Trinidad, Guyana, and Suriname), Chinese, and Lebanese-Syrian populations; and 20th-century migration patterns have created large Caribbean diasporas in New York, Miami, Toronto, and London. The result is a region of extreme cultural creolization: Haitian Creole, Jamaican Patois, Trinidadian English-Creole, Papiamento (Dutch-Iberian-African mix on the ABC islands); musical genres including reggae, calypso, soca, salsa, son, merengue, bachata, zouk, and reggaeton; Indo-Caribbean Hindu and Muslim communities; santería, vodou, and obeah Afro-Caribbean religious practices alongside Catholic, Protestant, and Anglican traditions.

Frequently asked questions
What is the Caribbean?
The Caribbean is a geographic region of more than 7,000 islands, islets, reefs, and cays scattered across the Caribbean Sea between North and South America. It includes 13 sovereign nations and 20+ dependent territories, with about 44 million people total. The region is divided into the Greater Antilles (Cuba, Jamaica, Hispaniola, Puerto Rico) and the Lesser Antilles volcanic island arc, plus the Bahamas to the north.
Where is the Caribbean located?
The Caribbean lies in the western Atlantic Ocean, bounded by Central America to the west, the Gulf of Mexico to the northwest, the Atlantic Ocean to the east, and Venezuela/Colombia to the south. The Caribbean Sea itself covers approximately 2,754,000 km² and includes Latitudes roughly 9°N to 23°N, with the Tropic of Cancer crossing through the Bahamas at the region's northern edge.
What countries are in the Caribbean?
The 13 sovereign Caribbean nations are: Antigua and Barbuda, Bahamas, Barbados, Cuba, Dominica, Dominican Republic, Grenada, Haiti, Jamaica, St. Kitts and Nevis, St. Lucia, St. Vincent and the Grenadines, and Trinidad and Tobago. Major dependencies include Puerto Rico (USA), the Cayman Islands and British Virgin Islands (UK), Martinique and Guadeloupe (France), and Curaçao and Aruba (Netherlands).
What is the largest island in the Caribbean?
Cuba is the largest Caribbean island at 109,884 km² — nearly half of the region's total land area. Hispaniola (76,192 km²; divided between Haiti and the Dominican Republic) is second, followed by Jamaica (10,991 km²) and Puerto Rico (8,870 km²). Together these four "Greater Antilles" islands hold about 90% of the Caribbean's land and roughly 75% of its population.
Why does the Caribbean have so many hurricanes?
The Caribbean lies entirely within the Atlantic hurricane belt — the latitudes (10–25°N) and warm sea surface temperatures (typically 28°C+ in the August-October peak) where tropical cyclones develop and strengthen. Northeasterly trade winds steer storms westward across the region from their formation zones in the central Atlantic. The Caribbean averages about 12 named storms per year, with roughly 6 reaching hurricane strength.
