Africa's economic map redrew itself: GDP by sub-region and bloc, 1990–2024

The headline number is straightforward: African GDP in current US dollars went from $546 billion in 1990 to $2.89 trillion in 2024. A roughly five-fold nominal expansion over thirty-five years, with most of the gain concentrated in the post-2000 period.

The interesting story isn't the total. It's what shifted underneath it. The continent's economic centre of gravity has moved — slowly through the 1990s, then sharply through the 2000s and 2010s commodity boom, and then in a different direction again post-2020. The composition of African GDP today looks meaningfully different from the composition of 1990 or even 2014.

One housekeeping note before we start. There are several ways to slice Africa into sub-regions. We use two complementary lenses in this piece: the African Union's five non-overlapping regional groupings, and the major AU-recognised Regional Economic Communities (RECs). We don't use the UN Statistics Division's M.49 framework, which puts Zimbabwe, Zambia, Malawi, and Mozambique into "Eastern Africa" — a latitude-driven classification that contradicts how the AU and the countries themselves describe their region.

Northern Africa is still #1. Eastern Africa more than doubled.

Across the entire 1990–2024 window, Northern Africa has held the largest share of African GDP — driven by Egypt, Algeria, and Morocco. Its share has fallen modestly, from 38.6% in 1990 to 33.9% in 2024. Still #1, by a comfortable margin.

Southern Africa — using the AU's definition that includes South Africa, Angola, Zimbabwe, Zambia, Botswana, Namibia, Lesotho, Eswatini, Mozambique, Malawi — held second place throughout the window, but lost seven percentage points of share (29.3% → 22.2%). South Africa's long real-growth slowdown and rand depreciation against the dollar are the main drivers; Angola's post-2014 oil-price decline reinforces it.

Western Africa (ECOWAS, basically) stayed in third place with a modest share gain: 17.9% → 20.8%. The gain is smaller than it looks because Nigeria's 2023–24 naira unification compressed the region's nominal-USD figures. In local-currency terms the region has grown solidly.

The most dramatic move is Eastern Africa — Kenya, Ethiopia, Tanzania, Uganda, Madagascar, Mauritius, Rwanda et al — going from 7.4% to 15.7% of African GDP. Share more than doubled. Ethiopia's expansion from $12bn in 2000 to $150bn in 2024 is the single largest driver; Kenya's near-tripling over the same window reinforces it. Central Africa, the smallest region in both 1990 and 2024, edged modestly higher (6.8% → 7.4%).

Who Africa's biggest economies are today

As recently as 2022, Nigeria was unambiguously Africa's largest economy. Two years later the picture is unrecognisable. South Africa narrowly holds the top spot in 2024 at $401 billion. Egypt sits very close behind at $389 billion — close enough that 2025 could flip the ranking. Algeria is at $269 billion. Nigeria has dropped to $252 billion — a 62% decline from its 2019 peak.

None of that Nigerian decline is a real-economy collapse. Nigerian real GDP continued to grow through this period. The collapse is the naira. The May 2023 partial devaluation and the January 2024 unification together cut the exchange-rate-implied USD value of Nigerian output roughly in half. The naira moved from around ₦460/USD at the start of 2023 to ₦1,500–1,700/USD by 2024. The economy still produces approximately the same amount; the World Bank just translates it into dollars at a much weaker rate.

Two takeaways follow. First: the standard "Nigeria is Africa's largest economy" framing is now wrong, and has been for a year. Second: in currencies where the official rate diverged significantly from the market rate for a long period (Nigeria, Egypt pre-2024, Ethiopia, Zimbabwe), the World Bank's "current USD" series is sensitive to exactly when policymakers close the gap. Use it with that context.

The fastest-growing economies

Compound annual growth rates from 2000 to 2024, computed in current US dollars, put Ethiopia (12.8%) and Ghana (12.4%) at the top of the African league table. Several Central African economies sit in the top ten — Chad, Equatorial Guinea, Angola — having ridden the 2003–2014 commodity supercycle. Kenya, Niger, and Uganda round out the top names.

The commodity-driven names need a caveat. Equatorial Guinea grew at 11% per year on average for two decades, but almost all of the gain came between 2000 and 2008 on the back of oil. Its GDP today is lower in real and nominal terms than it was in 2014. The CAGR captures the average; it hides the fact that most of these economies have been treading water for a decade.

Ethiopia, Ghana, Kenya, Uganda, Rwanda, and Tanzania have grown differently — more consistently, with more diversified drivers, less commodity-dependent. That distinction matters for what these economies look like in 2034.

Read through the economic blocs

Africa has eight AU-recognised Regional Economic Communities. They overlap heavily — Tanzania sits in both SADC and EAC, DRC sits in four blocs, Egypt sits in AMU and COMESA. That overlap is a feature, not a bug: African integration is designed to be multi-layered. The numbers below sum each bloc independently, accepting the double-counting.

COMESA is the largest bloc by GDP at $1.16 trillion in 2024 — 21 members spanning Egypt, Libya, Sudan, Kenya, Ethiopia, Zambia, Zimbabwe and more. It's also the most overlapping; the headline number bundles economies that are also separately members of SADC, EAC, AMU, and ECCAS. COMESA's economic significance is more as a continental trade-preference framework than as a unified bloc.

SADC is second at $829 billion — anchored by South Africa, Angola, Tanzania, and DRC. Its 5.4% per annum CAGR over 2000–2024 lags the continental average, dragged by South Africa's low growth.

ECOWAS is third at $601 billion — Nigeria dominates (and dominates the bloc's recent USD trajectory through naira moves). The 15-member bloc has grown at 7.0% per annum since 2000, despite Nigeria's recent currency-driven contraction.

AMU (Arab Maghreb Union) sits at $541 billion with just five members — Algeria, Morocco, Tunisia, Libya, Mauritania. The bloc is politically dormant (no functional integration secretariat since the 1990s) but the economic mass is real.

EAC is fifth at $341 billion with seven members. It's the smallest of the major active blocs but the fastest-growing at 7.96% CAGR — faster than ECOWAS, SADC, ECCAS, COMESA, AMU, and the African continental average. It was also the only major bloc that grew in real terms through 2020 (more on that below).

ECCAS (Central African states) at $315 billion is the smallest of the major active blocs and the only major bloc whose membership is dominated by commodity exporters. Its 7.7% CAGR overstates the recent trajectory because of the 2000s commodity boom.

COVID-19, measured properly

Asking "who was hit hardest by COVID" requires picking a metric, and the choice matters more than people expect. The intuitive metric — change in GDP measured in current US dollars — turns out to overstate the pandemic damage in resource-exporting and floating-currency economies. Angola's nominal-USD GDP fell 27% from 2019 to 2020, but its real GDP fell only 4%; the rest was the oil-price collapse and the kwanza depreciation. Zambia's USD GDP fell 22% while its real GDP fell less than 3%, because the kwacha collapsed in the same window. Neither story is well-described as "COVID damage."

The cleaner metric is real GDP growth. The World Bank publishes it; we use it here. The picture is different from the dollar-flow picture in important ways.

By AU sub-region, GDP-weighted: Southern Africa was the hardest-hit region in real terms (−5.7% in 2020), reflecting South Africa's −6.2% contraction, Botswana's −8.7%, Namibia's −8.1%, and Lesotho's −8.2%. Western Africa (−4.4%) and Northern Africa (−4.2%) came next, both heavily weighted by Nigeria and Egypt-plus-Libya respectively. Central Africa was relatively shallow at −1.0%, partly because Rwanda kept growing. Eastern Africa was the only African region that grew through 2020 — at +1.2% on a GDP-weighted basis, against a global average of −2.7%. Ethiopia's continued +6.1% real growth, Kenya's nearly-flat −0.3%, Tanzania's +2.0%, and Uganda's +2.9% pulled the regional average up against Mauritius and Seychelles dragging it down.

By REC bloc, GDP-weighted: AMU was the hardest-hit bloc at −9.8% — Libya's −29% real contraction dominates. SADC came next at −4.8% (South Africa-led). ECOWAS at −4.4%. ECCAS at −2.0%. COMESA at −1.4%. EAC was the only major bloc that grew through 2020, at +0.8% real.Three of the five bloc rankings line up with the sub-regional rankings; AMU and COMESA show up because of which countries they aggregate.

For context: the global real-GDP contraction in 2020 was −2.7%; the emerging-and-developing economy aggregate was −1.8%. Eastern Africa and the EAC bloc outperformed the world. The other African regions and blocs underperformed it.

The worst-hit countries

Libya leads the worst-hit ranking by a wide margin — real GDP fell 29.5% in 2020. This is not primarily a pandemic statistic. Libya's 2020 contraction combines COVID with the country's ongoing civil conflict and a multi-month shutdown of oil-export terminals. Treat it as a special case.

The cleanest "COVID-only" cases are the tourism-dependent economies. Cabo Verde fell 20.8%, Mauritius 14.6%, Seychelles 11.7%. Tourism receipts in all three account for 20–30% of GDP in normal years; international travel stopped in March 2020 and only partially recovered in 2021. These are textbook cases of single-channel exposure to a global shock.

Tunisia (−9.0%), Botswana (−8.7%), Lesotho (−8.2%), and Namibia (−8.1%) round out the next tier — a mix of tourism, mining (diamonds for Botswana), and heavy lockdown impact. South Africa's −6.2% sat in the middle of the African distribution. Madagascar, Morocco, and Nigeria all contracted by 6–7% despite very different underlying causes — Morocco a tight lockdown, Nigeria an oil-price shock, Madagascar a tourism-plus-trade-shock.

A useful contrast: Egypt, Ethiopia, Tanzania, Côte d'Ivoire, Benin, Niger, Ghana, Rwanda, and Mozambique all grew in real terms in 2020. The common features of the African economies that did well were lower tourism exposure, lower commodity-export dependence, less stringent lockdowns, and stronger agriculture-and-services bases that weren't shut down.

What this looks like in 2034

A handful of trends in the data point in the same direction.

Eastern Africa's share-gain has been roughly linear over thirty years; if it continues at the same rate, the region overtakes Western Africa as the second-largest sub-region around 2033–2035. That requires Ethiopia and Kenya to keep expanding at something close to the pace they've maintained for two decades. Neither is guaranteed — Ethiopia's macroeconomic situation in 2024–25 has been rough — but the structural trajectory is clear.

Southern Africa is the inverse story. South Africa's real growth has averaged ~1.5% over 2010–2024, well below population growth. Unless that changes, the AU-Southern share will continue to fall and the SADC bloc will continue to underperform the continental average.

The Nigeria question is mostly about whether the naira stabilises. If the 2024 exchange rate is the new equilibrium, Nigeria sits fourth in the African GDP table for the foreseeable future and ECOWAS's headline numbers stay compressed. If the naira recovers meaningfully (which would require sustained current-account surpluses and tighter monetary policy), Nigeria reclaims #1 quickly. Most observers expect gradual nominal appreciation but not a full recovery to 2022 levels.

And Egypt's economic gravity in Africa keeps growing whether or not its politics gets easier. At $389 billion it's a hair behind South Africa today; with Egyptian real growth running well ahead of South African real growth in most years, Egypt likely overtakes South Africa for the #1 spot during the next two to four years.

Among the blocs, EAC is the one to watch. Its 7.96% per-year compound growth rate since 2000 is the fastest on the continent; it's the only bloc that grew through 2020; and its member states are integrating more deeply (common market, single currency aspirations, customs union since 2005). If EAC continues at its current trajectory, it overtakes ECCAS by 2027 and AMU by 2034 in nominal-USD terms.

Methodology

Two regional lenses. The AU sub-regional grouping is the African Union's own five non-overlapping classification (Northern, Western, Central, Eastern, Southern). It places Zimbabwe, Zambia, Malawi, Mozambique, and Angola in Southern Africa, where they sit politically and economically. We avoided the UN M.49 statistical convention because it places those countries in "Eastern Africa" on latitude grounds — defensible for global statistical aggregation but misleading for African economic analysis.

The REC bloc lens uses the eight AU-recognised Regional Economic Communities, of which we report the six most active by economic mass (ECOWAS, SADC, EAC, ECCAS, COMESA, AMU). These overlap heavily by design — Tanzania is in both EAC and SADC, DRC sits in four blocs, Egypt sits in AMU and COMESA. Each bloc is summed independently. The totals across blocs can't be added together to recover the continental sum because of the overlap.

Regional COVID impact uses country-level real GDP growth in 2020, weighted by 2019 USD GDP shares (to avoid using pandemic-year weights). Compound annual growth rates use the standard endpoint formula. All charts pull directly from the indicator files; no data has been smoothed or interpolated. Reference global figures (−2.7% world, −1.8% EMDE, −3.9% advanced economies for 2020) come from the IMF World Economic Outlook.

For nominal-USD comparisons across long windows, particularly for economies with managed or recently-unified exchange rates (Nigeria, Egypt pre-2024, Ethiopia, Zimbabwe), current-USD GDP can shift sharply in years when the official rate is moved closer to the market rate. We discuss this directly in the Nigeria section.
