Botswana vs South Africa: Side-by-Side Comparison
South Africa is the bigger country: it covers 1,221,037 km² against Botswana's 581,730 km² and has about 64.0 million people against only 2.5 million in Botswana (2024 UN estimates). South Africa's 2024 GDP of about $400 billion is some 21 times Botswana's $19 billion, but Botswana produces more per person (about $7,600 against $6,250). The two neighbours share a border of nearly 2,000 km and the world's oldest customs union.
Key Differences at a Glance
- Size: South Africa is about 2.1 times larger by area and has about 26 times as many people.
- Wealth per person: Botswana's GDP per capita (about $7,600) is higher than South Africa's (about $6,250), thanks to diamonds and a small population.
- Density: Botswana, with about 4 people per km², is one of the most sparsely populated countries in the world; South Africa has about 52.
- Sea access: Botswana is landlocked and ships much of its trade through South African ports.
- Economy: Botswana depends heavily on diamonds; South Africa has Africa's most diversified industrial economy.

Population
South Africa has the far larger population, with about 64.0 million people against Botswana's 2.5 million (2024 UN estimates), roughly 26 times as many. Statistics South Africa's own mid-year estimate is slightly lower, at about 63 million. Johannesburg's metropolitan area alone has more than twice as many people as the whole of Botswana.
The two also differ in how people are spread out. South Africa is heavily urbanised, with about two-thirds of its people in towns and cities such as Johannesburg, Pretoria, Cape Town and Durban. Botswana's people live mainly along the eastern corridor near the South African border, from Lobatse through Gaborone to Francistown, while the Kalahari interior is almost empty; the average density is only about 4 people per km². Both countries were among the hardest hit by HIV/AIDS in the 1990s and 2000s and have since run some of Africa's largest treatment programmes, which have pushed life expectancy back up to about 69 years in Botswana and about 66 in South Africa.
Area and Geography
South Africa covers 1,221,037 km² against Botswana's 581,730 km², about 2.1 times the size. South Africa has coastlines on the Atlantic and Indian Oceans; Botswana is landlocked between South Africa, Namibia, Zimbabwe and Zambia (the Zambia border is a short stretch at Kazungula, crossed by a bridge opened in 2021).
The Kalahari covers about 70% of Botswana, but the country also contains the Okavango Delta, a UNESCO World Heritage Site and one of the world's largest inland deltas, as well as the Makgadikgadi salt pans and the Chobe River's elephant herds. South Africa ranges from the Highveld plateau and the Drakensberg mountains to the semi-arid Karoo, the winter-rainfall Western Cape and the subtropical Lowveld of Kruger National Park. The southern Kalahari extends across the border into South Africa's Northern Cape.
The Botswana–South Africa Border
The border is about 1,969 km long, running along Botswana's southern and south-eastern edge. In the east it follows the Limpopo River and its tributary the Marico (Madikwe); in the south it follows the Molopo River; and in the far south-west the Nossob River separates the two halves of the Kgalagadi Transfrontier Park. Kgalagadi, formed from South Africa's Kalahari Gemsbok National Park and Botswana's Gemsbok National Park, was formally opened in 2000 as Africa's first transfrontier park, and visitors can move within it without normal border formalities if they exit through the same country.
The busiest crossings are Tlokweng–Kopfontein, about 20 km from Gaborone on the road to Zeerust and Johannesburg, and Ramatlabama near Mafikeng; others include Skilpadshek–Pioneer Gate near Lobatse and Martin's Drift–Groblersbrug on the road to Limpopo province. Gaborone lies only about 20 km from the South African border.
Economy
South Africa's 2024 GDP of about $400 billion (IMF/World Bank estimates) is roughly 21 times Botswana's $19 billion. Per person the picture reverses: Botswana produces about $7,600 per head against about $6,250 in South Africa, making it one of the wealthier countries in mainland Africa. Both are classed by the World Bank as upper-middle-income, and both have very high income inequality.
Botswana's economy rests on diamonds, mined mainly by Debswana, a 50:50 venture between the government and De Beers; diamonds provide most export earnings and a large share of government revenue. Since independence Botswana has used that revenue to build roads, schools and clinics and to save through the Pula Fund. A slump in global diamond demand since 2023 has cut export earnings and slowed growth, adding urgency to efforts to diversify into tourism, beef, copper and services. South Africa is far more diversified, with mining (platinum, gold, coal, manganese), vehicle manufacturing, finance and retail, but it struggles with slow growth, electricity problems and unemployment above 30%.
Language and Culture
English is an official language in both countries, which makes business and travel straightforward. Botswana's national language is Setswana, spoken by most of the population. South Africa has 12 official languages, including isiZulu, isiXhosa, Afrikaans, English, Sesotho, Setswana and South African Sign Language (added in 2023). The Tswana people straddle the border: there are more Setswana speakers in South Africa, mainly in North West province, than in Botswana itself, a legacy of the colonial boundary drawn in the 1880s.
Botswana's culture is closely tied to cattle, and the kgotla, a traditional community assembly, still plays a role in local decision-making. South Africa's culture blends African, European and Asian influences, from Zulu and Xhosa traditions to Afrikaner and Cape Malay heritage. Christianity is the majority religion in both.
Currency
Botswana uses the pula (BWP) and South Africa the rand (ZAR). Botswana left the rand monetary area and introduced the pula in 1976. Today it manages the pula through a crawling peg against a basket of currencies in which the rand carries a large weight, so the two tend to move together, but the pula is usually worth more than the rand. South Africa, Lesotho, Eswatini and Namibia share the Common Monetary Area; Botswana does not, so rand notes are not legal tender in Botswana, although they are accepted in some border towns.
History and Independence
Botswana was the British protectorate of Bechuanaland from 1885. Tswana chiefs lobbied London to keep it out of Cecil Rhodes's control and, later, out of the Union of South Africa. It became independent on 30 September 1966 as one of the world's poorest countries, and diamonds were discovered at Orapa the following year. Botswana has held regular multi-party elections ever since; in 2024 the Botswana Democratic Party lost power for the first time since independence, in a peaceful handover.
South Africa became a self-governing Union in 1910 and a republic in 1961. Apartheid, the system of legal racial segregation, lasted from 1948 until the first democratic elections in 1994. Botswana sheltered refugees from apartheid and was occasionally raided by South African forces, notably in Gaborone in 1985. After 1994 the relationship became one of close partnership.
Botswana–South Africa Relations, Trade and Travel
The two economies are tightly linked. Both belong to the Southern African Customs Union (SACU), founded in 1910 and generally described as the world's oldest customs union, together with Lesotho, Eswatini and Namibia. SACU customs revenue, shared under a formula, is a major source of Botswana's government income. South Africa supplies a majority of Botswana's imports, from food and fuel to vehicles and machinery, and many Batswana study, shop and seek medical care in South Africa. Botswana's rail line, built in the 1890s, is part of the historic route from South Africa to Zimbabwe.
For travellers, Gaborone is about 360 km (roughly four to five hours) by road from Johannesburg via Tlokweng–Kopfontein, and there are daily flights between Johannesburg and Gaborone, Maun and Kasane. Both countries drive on the left. A common safari route combines Kruger in South Africa with the Okavango Delta and Chobe in Botswana, while self-drive visitors cross into the Kgalagadi Transfrontier Park.
Which Country Is Bigger?
South Africa is bigger on the headline measures: it covers 1,221,037 km² against Botswana's 581,730 km² (about 2.1 times larger), has about 64.0 million people against 2.5 million (about 26 times), and its 2024 GDP of about $400 billion is roughly 21 times Botswana's $19 billion. Botswana's one clear lead is GDP per person, about $7,600 against $6,250.
