The US Central Intelligence Agency (CIA) reports that in 2001 Fiji's gross domestic product (GDP) was estimated at $4.4 billion. The per capita GDP was estimated at $5,200. The average inflation rate in 2000 was 3%. 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 17% of GDP, industry 25%, and services 58%. Foreign aid receipts amounted to about $32 per capita and accounted for approximately 2% of the gross national income (GNI). It was estimated that in 1991 about 26% of the population had incomes below the poverty line.
