Iraq's economy is dominated by the oil sector, which has traditionally provided about 95% of foreign exchange earnings. The lack of development in other sectors has resulted in 18%–30% unemployed and a per capita GDP of $4,000. Public sector employment accounted for nearly 60% of full-time employment in 2011. The oil export industry, which dominates the Iraqi economy, generates very little employment. Currently only a modest percentage of women (the highest estimate for 2011 was 22%) participate in the labour force.
