one of the world's longest periods of economic boom (1966–1999).

 The United Nations predicts Africa’s economic growth will reach 3.5% in 2018 and 3.7% in 2019. As of 2007, growth in Africa had surpassed that of East Asia. Data suggest parts of the continent are now experiencing fast growth, thanks to their resources and increasing political stability and 'has steadily increased levels of peacefulness since 2007'. The World Bank reports the economy of Sub-Saharan African countries grew at rates that match or surpass global rates. According to the United Nations Department of Economic and Social Affairs, the improvement in the region’s aggregate growth is largely attributable to a recovery in Egypt, Nigeria and South Africa, three of Africa’s largest economies.

The economies of the fastest growing African nations experienced growth significantly above the global average rates. The top nations in 2007 include Mauritania with growth at 19.8%, Angola at 17.6%, Sudan at 9.6%, Mozambique at 7.9% and Malawi at 7.8%. Other fast growers include Rwanda, Mozambique, Chad, Niger, Burkina Faso, Ethiopia. Nonetheless, growth has been dismal, negative or sluggish in many parts of Africa including Zimbabwe, the Democratic Republic of the Congo, the Republic of the Congo and Burundi. Many international agencies are increasingly interested in investing in emerging African economies. especially as Africa continues to maintain high economic growth despite current global economic recession.
The rate of return on investment in Africa is currently the highest in the developing world.

Debt relief is being addressed by some international institutions in the interests of supporting economic development in Africa. In 1996, the UN sponsored the Heavily Indebted Poor Countries (HIPC) initiative, subsequently taken up by the IMF, World Bank and the African Development Fund (AfDF) in the form of the Multilateral Debt Relief Initiative (MDRI). As of 2013, the initiative has given partial debt relief to 30 African countries.

Trade has driven much of the growth in Africa's economy in the early 21st century. China and India are increasingly important trade partners; 12.5% of Africa's exports are to China, and 4% are to India, which accounts for 5% of China's imports and 8% of India's. The Group of Five (Indonesia, Malaysia, Saudi Arabia, Thailand, and the United Arab Emirates) are another increasingly important market for Africa's exports.

Africa's economy—with expanding trade, English language skills (official in many Sub-Saharan countries), improving literacy and education, availability of splendid resources and cheaper labour force—is expected to continue to perform better into the future. Trade between Africa and China stood at US$166 billion in 2011.

Africa will only experience a "demographic dividend" by 2035, when its young and growing labour force will have fewer children and retired people as dependents as a proportion of the population, making it more demographically comparable to the US and Europe. It is becoming a more educated labour force, with nearly half expected to have some secondary-level education by 2020. A consumer class is also emerging in Africa and is expected to keep booming. Africa has around 90 million people with household incomes exceeding $5,000, meaning that they can direct more than half of their income towards discretionary spending rather than necessities. This number could reach a projected 128 million by 2020.

During the President of the United States Barack Obama's visit to Africa in July 2013, he announced a US$7 billion plan to further develop infrastructure and work more intensively with African heads of state. A new program named Trade Africa, designed to boost trade within the continent as well as between Africa and the U.S., was also unveiled by Obama.

The seemingly intractable nature of Africa's poverty has led to debate concerning its root causes. Endemic warfare and unrest, widespread corruption, and despotic regimes are both causes and effects of the continued economic problems. The decolonization of Africa was fraught with instability aggravated by cold war conflict. Since the mid-20th century, the Cold War and increased corruption and despotism have also contributed to Africa's poor economy.

According to the researchers at the Overseas Development Institute, the lack of infrastructure in many developing countries represents one of the most significant limitations to economic growth and achievement of the Millennium Development Goals (MDGs). Infrastructure investments and maintenance can be very expensive, especially in such areas as landlocked, rural and sparsely populated countries in Africa.

It has been argued that infrastructure investments contributed to more than half of Africa's improved growth performance between 1990 and 2005 and increased investment is necessary to maintain growth and tackle poverty. The returns to investment in infrastructure are very significant, with on average 30–40% returns for telecommunications (ICT) investments, over 40% for electricity generation, and 80% for roads.

In Africa, it is argued that to meet the MDGs by 2015, infrastructure investments would need to reach about 15% of GDP (around $93 billion a year). Currently, the source of financing varies significantly across sectors. Some sectors are dominated by state spending, others by overseas development aid (ODA) and yet others by private investors. In sub-Saharan Africa, the state spends around $9.4 billion out of a total of $24.9 billion.

In irrigation, SSA states represent almost all spending; in transport and energy a majority of investment is state spending; in Information and communication technologies and water supply and sanitation, the private sector represents the majority of capital expenditure. Overall, aid, the private sector and non-OECD financiers between them exceed state spending. The private sector spending alone equals state capital expenditure, though the majority is focused on ICT infrastructure investments. External financing increased from $7 billion (2002) to $27 billion (2009). China, in particular, has emerged as an important investor.

The economic impact of the colonization of Africa has been debated. In this matter, the opinions are biased between
researchers, some of them consider that Europeans had a positive impact on Africa; others affirm that Africa's development was slowed down by colonial rule. The principal aim of colonial rule in Africa by European colonial powers was to exploit natural wealth in the African continent at a low cost. Some writers, such as Walter Rodney in his book "How Europe Underdeveloped Africa", argue that these colonial policies are directly responsible for many of Africa's modern problems. Critics of colonialism charge colonial rule with injuring African pride, self-worth and belief in themselves. Other post-colonial scholars, most notably Frantz Fanon continuing along this line, have argued that the true effects of colonialism are psychological and that domination by a foreign power creates a lasting sense of inferiority and subjugation that creates a barrier to growth and innovation. Such arguments posit that a new generation of Africans free of colonial thought and mindset is emerging and that this is driving economic transformation.

Historians L. H. Gann and Peter Duignan have argued that Africa probably benefited from colonialism on balance. Although it had its faults, colonialism was probably "one of the most efficacious engines for cultural diffusion in world history". These views, however, are controversial and are rejected by some who, on balance, see colonialism as bad. The economic historian David Kenneth Fieldhouse has taken a kind of middle position, arguing that the effects of colonialism were actually limited and their main weakness wasn't in deliberate underdevelopment but in what it failed to do. Niall Ferguson agrees with his last point, arguing that colonialism's main weaknesses were "sins of omission". Analysis of the economies of African states finds that independent states such as Liberia and Ethiopia did not have better economic performance than their post-colonial counterparts. In particular the economic performance of former British colonies was better than both independent states and former French colonies.

Africa's relative poverty predates colonialism. Jared Diamond argues in Guns, Germs, and Steel that Africa has always been poor due to a number of ecological factors affecting historical development. These factors include low population density, lack of domesticated livestock and plants and the North-South orientation of Africa's geography. However Diamond's theories have been criticized by some including James Morris Blaut as a form of environmental determinism. Historian John K. Thornton argues that sub-Saharan Africa was relatively wealthy and technologically advanced until at least the seventeenth century. Some scholars who believe that Africa was generally poorer than the rest of the world throughout its history make exceptions for certain parts of Africa. Acemoglue and Robinson, for example, argue that most of Africa has always been relatively poor, but "Aksum, Ghana, Songhay, Mali, [and] Great Zimbabwe... were probably as developed as their contemporaries anywhere in the world." A number of people including Rodney and Joseph E. Inikori have argued that the poverty of Africa at the onset of the colonial period was principally due to the demographic loss associated with the slave trade as well as other related societal shifts. Others such as J. D. Fage and David Eltis have rejected this view.

African countries suffer from communication difficulties caused by language diversity. Greenberg's diversity index is the chance that two randomly selected people would have different mother tongues. Out of the most diverse 25 countries according to this index, 18 (72%) are African. This includes 12 countries
