The US Central Intelligence Agency (CIA) reports that in 2001 Micronesia's gross domestic product (GDP) was estimated at $269 million. The per capita GDP was estimated at $2,000. The annual growth rate of GDP was estimated at 2%. The average inflation rate in 2001 was 2.5%. 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 50% of GDP, industry 4%, and services 46%. Foreign aid receipts amounted to about $1,440 per capita and accounted for approximately 52% of the gross national income (GNI).
