Accra sits on the Gulf of Guinea coast at approximately 5.6 degrees north latitude, occupying the Greater Accra Region at the southeastern corner of Ghana. The city extends across 225.7 square kilometers of coastal savanna, bounded by the Atlantic Ocean to the south and stretching inland across relatively flat terrain that rises gradually from sea level to roughly 61 meters at its northern edges. The Odaw River flows through the eastern portions of the city, emptying into the Korle Lagoon, a brackish water body that separates central Accra from industrial zones to the west. The Densu River marks the western boundary of the metropolitan area, creating a natural division between Accra proper and its western suburbs. Rainfall follows a bimodal pattern with a major rainy season from April through June and a minor season in October, depositing an annual average of 730 millimeters—significantly less than most other West African capitals at comparable latitudes. Temperatures remain consistent throughout the year, ranging from 24 to 28 degrees Celsius, with the harmattan winds from the Sahara bringing dry, dusty conditions between December and February.
The population of metropolitan Accra reached approximately 2.27 million in the 2021 census, making it Ghana's largest urban center and containing roughly seven percent of the national population. The Greater Accra Metropolitan Area, which includes peripheral municipalities such as Tema, Ashaiman, and Ga South, holds an estimated 4.1 million people. Population density in central districts exceeds 9,000 persons per square kilometer, particularly in neighborhoods like Nima, Mamobi, and James Town. The city's demographic composition reflects internal migration patterns, with substantial communities from the Ashanti Region, Northern Region, and Volta Region supplementing the indigenous Ga population. Ethnic Ga people constitute approximately 18.9 percent of the metropolitan population according to 2010 census data, with Akan groups collectively representing around 39.8 percent and Ewe populations approximately 10.7 percent. The city's growth rate has averaged 3.1 percent annually since 2000, driven primarily by rural-to-urban migration rather than natural increase. English serves as the administrative and commercial language, while Ga and Akan languages, particularly Twi, function as widespread lingua francas in informal settings.
Accra's urban fabric divides into distinct zones with different origins and functions. The historical core consists of Ga settlements including James Town, Ussher Town, and Osu, established as fishing communities before European contact. James Town developed around British Fort James, constructed in 1673, while Ussher Town grew near Ussher Fort, built by the Dutch in 1649 as Fort Crèvecoeur. Osu expanded around Christiansborg Castle, erected by Danish traders in 1661 and later serving as the seat of colonial administration and post-independence government until 2013. These coastal neighborhoods retain dense, irregular street patterns with compounds housing extended families in single-story structures built from sandcrete blocks. The colonial administrative quarter occupies elevated ground north of James Town, where the British established planned neighborhoods with wider streets, drainage systems, and buildings constructed to European specifications. Ridge, the former European residential area, sits on higher ground with tree-lined avenues and larger plot sizes, remaining an affluent neighborhood housing embassies and government ministers. Independence-era expansion produced estates like Kaneshie, Achimota, and Dansoman, planned communities built between 1957 and 1980 with grid layouts and standardized housing blocks.
The central business district centers on Kwame Nkrumah Avenue and Kojo Thompson Road, where commercial buildings rise to 10-15 stories, relatively modest by international standards due to building code restrictions and geological considerations. The Bank of Ghana headquarters, completed in 2016, stands 15 stories and represents one of the taller structures in the downtown area. Makola Market occupies several city blocks near the intersection of Kojo Thompson Road and Pagan Road, operating as West Africa's largest informal market with an estimated 10,000 to 15,000 vendors selling textiles, food, household goods, and manufactured items. The market generates daily transactions estimated at 2-3 million cedis, though precise figures remain unavailable due to the predominantly cash-based informal economy. High Street preserves colonial-era commercial buildings with covered arcades, though many structures show deterioration from inadequate maintenance and tropical weathering. The Accra Mall, opened in 2008 in Tetteh Quarshie, introduced the country's first modern shopping center with international retail chains, covering 20,000 square meters and attracting middle-class Ghanaians and expatriates.
Residential patterns reflect income stratification. Affluent neighborhoods like East Legon, Airport Residential Area, and Cantonments feature walled compounds with 4-6 bedroom houses, backup generators to manage power interruptions, and borehole water systems. Property values in East Legon Phase 2 reached approximately 800,000 to 1.5 million cedis for standard family homes as of 2023. Middle-class areas including Madina, Adenta, and Spintex Road contain mixture of single-family homes and multi-story apartment buildings, with units typically renting for 1,500 to 4,000 cedis monthly. Lower-income neighborhoods such as Nima, Agbogbloshie, and Chorkor consist of compound houses where multiple families share courtyard spaces, communal toilets, and standpipe water access. These areas display housing densities exceeding 15,000 persons per square kilometer, with structures built incrementally as families acquire resources. Informal settlements occupy marginal lands including flood-prone areas near the Odaw River and coastal zones subject to erosion, housing populations that lack secure tenure.
Transportation infrastructure shapes daily movement patterns. The city lacks a formal public transit system, relying instead on privately operated tro-tros—minibuses following fixed routes—and shared taxis. Tro-tro fares range from 2 to 10 cedis depending on distance, with vehicles typically accommodating 12-15 passengers in conditions of variable comfort and maintenance. The routes concentrate along major arteries including Kwame Nkrumah Avenue, Graphic Road, Winneba Road, and the Mallam-Gbawe Highway. Uber and Bolt ride-hailing services entered the market in 2016 and 2017 respectively, offering metered alternatives with base fares around 7 cedis and per-kilometer charges of approximately 2.5 cedis. Traffic congestion intensifies during morning rush hours from 0630 to 0930 and evening periods from 1630 to 2000, particularly at major intersections like the Kwame Nkrumah Circle, Achimota Roundabout, and Mallam Junction where journey times can triple compared to off-peak travel. The Accra-Tema Motorway, completed in 1965, connects the capital to the industrial port city of Tema 25 kilometers eastward, carrying an estimated 70,000 vehicles daily though designed for substantially lower capacity.
Kotoka International Airport occupies 490 hectares immediately northeast of the city center, unusual proximity that limits expansion possibilities while offering convenient access. Terminal 3, opened in 2018, added capacity to handle 1.25 million passengers annually, bringing total airport capacity to approximately 2 million. The facility serves as a West African hub for airlines including Africa World Airlines, which operates regional routes to cities such as Kumasi, Tamale, and Takoradi alongside international destinations. The airport's single runway measures 3,021 meters, accommodating wide-body aircraft including Boeing 777s and Airbus A330s operated by international carriers. Distance from the airport to central business district hotels measures 6-8 kilometers, traversable in 15-25 minutes during off-peak hours or 45-75 minutes during rush periods. The lack of rail connections means all passengers rely on taxis, ride-hailing services, or hotel shuttles.
