The US Central Intelligence Agency (CIA) reports that in 2002 Australia's gross domestic product (GDP) was estimated at $528 billion. The per capita GDP was estimated at $27,000. The annual growth rate of GDP was estimated at 3.6%. The average inflation rate in 2002 was 2.8%. 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 3% of GDP, industry 26%, and services 71%.
The World Bank reports that in 2000 per capita household consumption (in constant 1995 US dollars) was $14,105. Household consumption includes expenditures of individuals, households, and nongovernmental organizations on goods and services, excluding purchases of dwellings. It was estimated that for the same period private consumption grew at an annual rate of 2%. The richest 10% of the population accounted for approximately 25.4% of household consumption and the poorest 10% approximately 2.0%.
