Iraq's economic sectors reflect the state of devastation that the country has endured as a result of war. The economy has traditionally been heavily dependent on the oil sector, which accounted for more than 60 percent of the GDP before the Gulf War.

The manufacturing sector was hit by the shortage of imported raw materials and spare parts, while the collapse of the country's irrigation system in the aftermath of the war has left the agricultural sector in dire straits.
