Syria's share in global exports has eroded gradually since 2001. The real per capita GDP growth was just 2.5% per year in the 2000–2008 period. Unemployment is high at above 10%. Poverty rates have increased from 11% in 2004 to 12.3% in 2007. In 2007, Syria's main exports include crude oil, refined products, raw cotton, clothing, fruits, and grains. The bulk of Syrian imports are raw materials essential for industry, vehicles, agricultural equipment, and heavy machinery. Earnings from oil exports as well as remittances from Syrian workers are the government's most important sources of foreign exchange.
