The US Central Intelligence Agency (CIA) reports that in 1999 Monaco's gross domestic product (GDP) was estimated at $870 million. The per capita GDP was estimated at $27,000. The average inflation rate in 2001 was 1%. 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.
