Senegal vs Nigeria: Side-by-Side Comparison
Nigeria is far bigger than Senegal: it covers 923,768 km² against 196,722 km² (about 4.7 times larger), has about 232.7 million people against Senegal's 18.5 million (2024 UN estimates), and its 2024 GDP of about $252 billion is roughly eight times Senegal's $32 billion. Per person, though, Senegal now produces more, about $1,750 against Nigeria's $1,100. The two ECOWAS members are about 2,500 km apart and do not share a border.
Key Differences at a Glance

Population
Nigeria has about 232.7 million people and Senegal about 18.5 million (2024 UN estimates), so Nigeria has roughly 13 times as many. Nigeria is Africa's most populous country, home to about one in six Africans. It is also much more densely populated, with about 252 people per km² against about 94 in Senegal.
Both populations are very young, with median ages under 20. Senegal's people are concentrated in the west, especially the Dakar region, which holds more than a fifth of the population, and the groundnut basin around Touba, Thiès and Kaolack. Nigeria's are spread across dozens of large cities, including Lagos, Kano, Ibadan, Port Harcourt and the federal capital, Abuja. Both have large diasporas: Senegalese communities in France, Italy and Spain, and Nigerian communities in the UK, the US and across Africa.
Area and Geography
Nigeria covers 923,768 km², about 4.7 times Senegal's 196,722 km². Senegal lies at the western tip of Africa, where the Pointe des Almadies near Dakar is the westernmost point of the African mainland; it is mostly flat and semi-arid, with the Senegal River along its northern border, the greener Casamance in the south, and The Gambia almost enclosed within its territory. Nigeria stretches from the Gulf of Guinea to the Sahel near Lake Chad, taking in the mangroves and oil fields of the Niger Delta, rainforest, the savanna of the Middle Belt and the Jos Plateau.
Both have Atlantic coasts and important ports: Dakar, which also serves landlocked Mali, and Lagos and Port Harcourt in Nigeria. They do not share a border; several countries lie between them along the West African coast.
Economy
Nigeria's 2024 GDP was about $252 billion (IMF/World Bank estimates, using the rebased series published in 2025) and Senegal's about $32 billion, so Nigeria's economy is roughly eight times larger. Per person, however, Senegal produces about $1,750 and Nigeria about $1,100. Nigeria's dollar GDP fell sharply after the naira was devalued in 2023–24, so it is no longer Africa's largest economy in US dollar terms, trailing South Africa, Egypt and Algeria; these rankings shift with exchange rates.
Nigeria's economy is dominated by oil and gas exports, alongside a huge farming sector, trade, telecoms, banking and fintech, and creative industries such as Nollywood and Afrobeats. Senegal's rests on services, fishing, phosphates, groundnuts, horticulture, tourism and remittances. It began producing offshore oil from the Sangomar field in 2024 and, with Mauritania, gas from the Greater Tortue Ahmeyim project, making both countries oil exporters. A 2024 audit found that Senegal's public debt was higher than previously reported, which has complicated its finances.
Language and Culture
Senegal's official language is French, a legacy of Dakar's role as the capital of French West Africa, but Wolof is the everyday lingua franca, alongside Pulaar, Serer, Diola and Mandinka. Nigeria's official language is English, with more than 500 languages, led by Hausa, Yoruba and Igbo, and Nigerian Pidgin as a widely used lingua franca. The Fula (Fulani) people, known as Peul or Haalpulaar in Senegal, live in both countries and across the Sahel.
Senegal is more than 90% Muslim, with influential Sufi brotherhoods such as the Mourides and Tijaniyya; the Tijaniyya order, whose major centre is in Kaolack, has many followers in northern Nigeria, a strong religious link between the two. Nigeria is roughly evenly divided between a mostly Muslim north and a mostly Christian south. Senegal is known for mbalax music, wrestling (laamb) and teranga (hospitality); Nigeria for Afrobeats, Nollywood and its food, including the jollof rice that both countries claim, since the dish is widely believed to originate with the Wolof of Senegal.
Currency
Senegal uses the West African CFA franc (XOF), issued by the Central Bank of West African States (BCEAO), which is based in Dakar, and pegged to the euro, keeping inflation relatively low. Nigeria uses the naira (NGN), which lost much of its value in 2023–24 when the central bank moved towards a market-determined exchange rate. The two currencies must be exchanged, usually via the US dollar or euro.
History and Independence
Senegal became independent from France in 1960, first as part of the short-lived Mali Federation and then on its own from 20 August 1960. Nigeria became independent from Britain on 1 October 1960. Senegal has since built one of Africa's most stable democracies: it has never had a military coup and has changed government through elections several times, most recently in 2024. Nigeria went through the Biafran civil war (1967–70) and long periods of military rule before returning to civilian government in 1999, since when it has held regular elections.
Senegal–Nigeria Relations, Trade and Travel
Both are founding members of ECOWAS, established in 1975, and cooperate on regional security and diplomacy; Senegalese troops served alongside Nigerian-led ECOWAS forces in Liberia in the early 1990s. Direct trade is modest because of distance and similar exports, but Nigerian companies are present in Senegal: Dangote Cement runs a plant near Dakar, and Nigerian banks such as UBA operate there. Nollywood films and Nigerian music are hugely popular in Dakar, while Senegalese musicians and footballers have large Nigerian followings.
ECOWAS citizens can travel between the two without a visa. Flights between Dakar and Lagos or Abuja take about four hours, often with a stop; overland travel through several countries is possible but takes days. Both drive on the right. Senegal uses UTC+0 and Nigeria UTC+1, so Lagos is one hour ahead of Dakar.
Which Country Is Bigger?
Nigeria is bigger on the headline measures: about 4.7 times Senegal's area (923,768 km² against 196,722 km²), about 13 times its population (232.7 million against 18.5 million) and about 8 times its GDP ($252 billion against $32 billion in 2024). Senegal leads on GDP per person, about $1,750 against $1,100.
