The US Central Intelligence Agency (CIA) reports that in 2001 Sa'udi Arabia's gross domestic product (GDP) was estimated at $241 billion. The per capita GDP was estimated at $10,600. The annual growth rate of GDP was estimated at 1.6%. The average inflation rate in 2001 was 1.7%. 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 7% of GDP, industry 48%, and services 45%. Aid receipts amounted to about $1 per capita.
