Editor's note: The article below highlights Africa's economic potential in ten charts. It has been put together by Michael Johnston, senior analyst for All Emerging Markets.
If some key hurdles can be cleared, Africa could experience explosive GDP growth over the coming decades.

At present, the contributions of Africa to the global economy are often overlooked. With a GDP of roughly $1.6 trillion, sub-Saharan Africa equals roughly 10 percent of the U.S. total and 2 percent of the global total. In the coming decades, however, Africa is poised to experience incredible growth that will make it a meaningful contributor to the global economy.
Population Explosion
Africa's population is expected to grow significantly over the next several decades, while many developed markets will grow only slightly. By 2050 Africa will have a population significantly larger than the current developed world, with one of every four global inhabitants living on the continent.

Africa will also be home to one of the largest individual countries in the world; by 2050, only India and China are expected to have more people than Nigeria. Nigeria's population is expected to be approximately 440 million in 2050. A simple visual helps to emphasize this point surrounding Africa's population; Nigeria, outlined below, will have 40 million more people than the U.S.

Growing Economies
Africa's economic importance is expected to increase not only because of its population growth. Four of the top five economies, as measured by expected 2016 GDP growth, are located in Africa.

Over extended periods of time, seemingly small differences in annual GDP growth can compound and result in very different trajectories. For example, PWC projects that Nigeria's economy will expand by about 5.4 percent annually through 2050 compared to a growth rate of 2.4 percent for the U.S.
That difference may seem nominal, but when compounded over 35 years it results in the following trajectories.

Available Land
Beyond simply large and growing populations and short-term GDP growth, real economic opportunity can be derived from natural resources.Hunger remains a major issue facing Africa; nearly a quarter of sub-Saharan Africa is undernourished, compared to about 14 percent in developing regions globally.
There is an opportunity for Africa to not only feed itself, but become a major exporter of agricultural commodities as well. The continent is home to a significant percentage of the world's "potentially available" cropland.

Broadband Penetration
While a relatively high number of Africans already use cell phones, penetration of smartphones and Internet connectivity is relatively low. But in coming years, hundreds of millions of Africans are expected to gain access to mobile broadband for the first time.

Moving in Right Direction
From several economic perspectives, Africa is moving in the right direction — in some cases quite quickly. Life expectancy has increased by two years since 2010, while the time needed to start a business has declined significantly.

Low-Hanging Fruit
While considerable progress has been made, there remains some significant low-hanging fruit that has the potential to extend life expectancy and provide economic stimulus.For example, the number of physicians in Africa is significantly lower than in other developing economies. Access to clean water and sanitation facilities is similarly well below the developing world average.

It's important to note that improvements in per capita GDP to reasonable levels — those currently prevailing in other developing economies — would result in enormous economic impact. If the per capita GDP in sub-Saharan Africa increases to the same level as China, global GDP would increase by $4.7 trillion, a roughly 6 percent increase. If the per capita GDP of sub-Saharan Africa increases to the same level as Greece, global GDP would increase by about $19 trillion — more than the total of the U.S.
