The US Central Intelligence Agency (CIA) reports that in 2001 Sudan's gross domestic product (GDP) was estimated at $49.3 billion. The per capita GDP was estimated at $1,360. The annual growth rate of GDP was estimated at 5.5%. The average inflation rate in 2001 was 10%. The CIA defines GDP as the value of all final goods and services produced within a nation in a given year and computed on the basis of purchasing power parity (PPP) rather than value as measured on the basis of the rate of exchange. It was estimated that agriculture accounted for 43% of GDP, industry 17%, and services 40%.
According to the United Nations, in 2000 remittances from citizens working abroad totaled $638 million or about $21 per capita and accounted for approximately 5.8% of GDP. Worker remittances in 2001 totaled $730.4 million. Foreign aid receipts amounted to about $5 per capita and accounted for approximately 2% of the gross national income (GNI).
