Real GDP in Saudi Arabia grew 6.6 percent in 4Q2011 against the year before, up from 5.1 per cent in the third quarter, according to data from the country's Central Department of Statistics.
The oil sector, which accounts for nearly a third of the Kingdom's economy, expanded 6.1 per cent in 4Q2011, the figures show.
Private sector growth, at 9.9 per cent, rapidly outpaced that of the state sector, which expanded 3.6 per cent.
A recent real estate boom and heavy government spending on infrastructure helped fuel a 13.3 per cent expansion in the construction sector.
