Economy In the mid-2010s, private capital flows to sub-Saharan Africa primarily from the BRICs, private-sector investment portfolios, and remittances began to exceed official development assistance.As of 2011, Africa is one of the fastest developing regions in the world. Six of the world's ten fastest-growing economies over the previous decade were situated below the Sahara, with the remaining four in East and Central Asia. Between 2011 and 2015, the economic growth rate of the average nation in Africa is expected to surpass that of the average nation in Asia. Sub-Saharan Africa is by then projected to contribute seven out of the ten fastest growing economies in the world. According to the World Bank, the economic growth rate in the region had risen to 4.7% in 2013, with a rate of 5.2% forecasted for 2014. This continued rise was attributed to increasing investment in infrastructure and resources as well as steady expenditure per household. 424 million people in sub-Saharan Africa were reportedly living in severe poverty in 2019.
