of the economic consequences of social and regional disparities is a sharp increase in Angolan private investments abroad. The small fringe of Angolan society where most of the asset accumulation takes place seeks to spread its assets, for reasons of security and profit. For the time being, the biggest share of these investments is concentrated in Portugal where the Angolan presence (including the family of the state president) in banks as well as in the domains of energy, telecommunications, and mass media has become notable, as has the acquisition of vineyards and orchards as well as of tourism enterprises. Angola has upgraded critical infrastructure, an investment made possible by funds from the nation's development of oil resources. According to a report, just slightly more than ten years after the end of the civil war Angola's standard of living has overall greatly improved. Life expectancy, which was just 46 years in 2002, reached 51 in 2011. Mortality rates for children fell from 25 per cent in 2001 to 19 per cent in 2010 and the number of students enrolled in primary school has tripled since 2001.

Natural resources The Economist reported in 2008 that diamonds and oil make up 60% of Angola's economy, almost all of the country's revenue and all of its dominant exports. Growth is almost entirely driven by rising oil production which surpassed in late 2005 and was expected to grow to by 2007. Control of the oil industry is consolidated in Sonangol Group, a conglomerate owned by the Angolan government. In December 2006, Angola was admitted as a member of OPEC. According to the
