The Angolan economy rebounded strongly after several years of low growth attributable to the lingering effects of the global financial crisis. Real gross domestic product (GDP) grew at an estimated rate of 7.9% in 2012 (up from 3.9% in 2011) on account of the strong performance of the energy, transportation and construction sectors. The outlook for 2013 and 2014 remains positive, with economic growth projected to reach 8.2% and 7.8%, respectively. This will be driven by a combination of continued expansion in the oil and gas sector and a public expenditure programme designed to encourage economic diversification.
