The US Central Intelligence Agency (CIA) reports that in 2002 Japan's gross domestic product (GDP) was estimated at $3.55 trillion. The per capita GDP was estimated at $28,000. The annual growth rate of GDP was estimated at -0.3%. The average inflation rate in 2002 was -0.9%. 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 1% of GDP, industry 31%, and services 68%.
According to the United Nations, in 2000 remittances from citizens working abroad totaled $505 million or about $4 per capita. Worker remittances in 2001 totaled $1.037 billion.
The World Bank reports that in 2001 per capita household consumption (in constant 1995 US dollars) was $24,306. Household consumption includes expenditures of individuals, households, and nongovernmental organizations on goods and services, excluding purchases of dwellings. Approximately 12% of household consumption was spent on food, 7% on fuel, 2% on health care, and 22% on education. The richest 10% of the population accounted for approximately 21.7% of household consumption and the poorest 10% approximately 4.8%.
