The US Central Intelligence Agency (CIA) reports that in 2000 Tonga's gross domestic product (GDP) was estimated at $225 million. The per capita GDP was estimated at $2,200. The annual growth rate of GDP was estimated at 5.3%. The average inflation rate in 2001 was 9.4%. 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 30% of GDP, industry 10%, and services 60%.
Worker remittances in 2001 totaled $52.53 million. Foreign aid receipts amounted to about $201 per capita and accounted for approximately 14% of the gross national income (GNI). Household consumption includes expenditures of individuals, households, and nongovernmental organizations on goods and services, excluding purchases of dwellings.
