The real estate and construction sectors in Algeria have been positively impacted by the country's growing economy and foreign investments. Algeria's GDP has grown from an average of 4% per year prior to 2001, to 9% thereafter. This growth has been largely driven by Algeria's ability to leverage its significant hydrocarbon reserves in times of rising oil prices. The country’s current account surplus stood at $28.9 Bn in 2006, accounting for 24.4% of its GDP, compared to $21.5 Bn in 2005 (20.7% of GDP).
