What is the current and future state of the economy of Africa?

Context:
The economy of Africa consists of the trade, industry, agriculture, and human resources of the continent. As of 2019, approximately 1.3 billion people were living in 54 countries in Africa. Africa is a resource-rich continent.  Recent growth has been due to growth in sales, commodities, services, and manufacturing. West Africa, East Africa, Central Africa and Southern Africa in particular, are expected to reach a combined GDP of $29 trillion by 2050.<|im_end|>

In March 2013, Africa was identified as the world's poorest inhabited continent; however, the World Bank expects that most African countries will reach "middle income" status (defined as at least US$1,025 per person a year) by 2025 if current growth rates continue.  There are a number of reasons for Africa's poor economy: historically, even though Africa had a number of empires trading with many parts of the world, many people lived in rural societies; in addition, European colonization and the later Cold War created political, economic and social instability.

However, as of 2013 Africa was the world's fastest-growing continent at 5.6% a year, and GDP is expected to rise by an average of over 6% a year between 2013 and 2023.  In 2017, the African Development Bank reported Africa to be the world's second-fastest growing economy, and estimates that average growth will rebound to 3.4% in 2017, while growth is expected to increase by 4.3% in 2018.  Growth has been present throughout the continent, with over one-third of African countries posting 6% or higher growth rates, and another 40% growing between 4% to 6% per year.  Several international business observers have also named Africa as the future economic growth engine of the world.<|im_end|>
