    "additionalInfo": "\u2013The Atlas methodology is used to reduce the impact of exchange rate fluctuations in the cross-country comparison of national incomes. The Atlas conversion factor for any year is the average of a country's exchange rate for that year and its exchange rates for the two preceding years, adjusted for the differences between the rate of inflation in the country and that in China, Japan, the United Kingdom, the United States, and the Euro area. A country's inflation rate is measured by the change in its GDP deflator. The inflation rate for the above countries, representing international inflation, is measured by the changes in the SDR deflator. (Special drawing rights, or SDRs, are the IMF's unit of account.)\n\u2013 Data on Serbia and Montenegro from 1992 to 2006 have been allocated to the sovereign states of Serbia and Montenegro, respectively. Similarly, the 15 post-Soviet States have been allocated the USSR's classification for 1990. This includes Moldova, Estonia, Latvia, Lithuania, Kazakhstan, Kyrgyzstan, Tajikistan, Turkmenistan, Uzbekistan, Russia, Armenia, Azerbaijan, Georgia, Ukraine, and Belarus. Similarly, Czechia and Slovakia have been assigned Czechoslovakia's classification in 1990 and 1991; Curacao and Sint Maarten (Dutch part) have been assigned the classification for the Netherlands Antilles from 1987 to 2009; and Serbia, Montenegro, Croatia, Slovenia, North Macedonia, and Bosnia and Herzegovina have been assigned the classification for Yugoslavia from 1987 to 1991.",
