"The reason the CIA figures differ from the LAEDC's, is that the CIA is converting from foreign currency to dollars using a "Purchasing Power Parity" (PPP) index, while the LAEDC is using exchange rates. That's also the reason why the LAEDC and the CIA report the same numbers for the U.S.: because there's no need to convert U.S. GDP from a foreign currency into dollars."
