Economy
The economy of Iran is the eighteenth largest economy in the world by purchasing power parity (PPP). Iran's economy is a mixture of central planning, state ownership of oil and other large enterprises, village agriculture, and small-scale private trading and service ventures. Its economic infrastructure has been improving steadily over the past two decades but continues to be affected by inflation and unemployment. In the early 21st century the service sector contributed the largest percentage of the GDP, followed by industry (mining and manufacturing) and agriculture. In 2006, about 45% of the government's budget came from oil and natural gas revenues, and 31% came from taxes and fees.
Government spending contributed to an average annual inflation rate of 14% in the period 2000–2004. As at 2007, Iran had earned $70 billion in foreign exchange reserves mostly (80%) from crude oil exports. In 2009 GDP was $336 billion ($876 billion at PPP), or $12,900 at PPP per capita. In 2008, Iran's official annual growth rate was 6%. Because of these figures and the country’s diversified but small industrial base, the United Nations classifies Iran's economy as semi-developed (1998).
