According to the International Monetary Fund, the Afghan economy grew 20% in the fiscal year ending in March 2004, after expanding 30% in the previous 12 months. The growth was attributed to international aid and to the end of droughts. An estimated $100 billion of aid had entered the nation from 2002 to 2021. A GDP of $4 billion in fiscal year 2003 was recalculated by the IMF to $6.1 billion, after adding proceeds from opium production. Mean graduate pay was $0.56 per man-hour in 2010. The country expects to be self sufficient in wheat, rice, poultry and dairy production by 2026.
