<P> Some countries / regions may have citizens which ar e on average wealthy . These countries / regions could appear in this list as having a small GDP . This would be because the country / region listed has a small population, and therefore small total economy; the GDP is calculated as the population times market value of the goods and services produced per person in the country . </P> <P> Comparisons of national wealth are also frequently made on the basis of purchasing power parity (PPP), to adjust for differences in the cost of living in different countries . PPP largely removes the exchange rate problem, but has its own drawbacks; it does not reflect the value of economic output in international trade, and it also requires more estimation than nominal GDP . On the whole, PPP per capita figures are more narrowly spread than nominal GDP per capita figures . </P> <Table> <Tr> <Th> Country </Th> <Th> Nominal GDP (2014 CIA estimate in millions USD) </Th> <Th> GDP per capita (2014 CIA estimate in USD) </Th> <Th> GDP (PPP) (IMF estimate in millions USD) </Th> <Th> GDP (PPP) per capita <P> (IMF estimate in USD) </P> </Th> </Tr> <Tr> <Td> Australia </Td> <Td> 1,444,000 </Td> <Td> 46,400 </Td> <Td> 1,188,764 </Td> <Td> 47,644.363 </Td> </Tr> <Tr> <Td> Federated States of Micronesia </Td> <Td> </Td> <Td> 3,000 </Td> <Td> 314 </Td> <Td> 3,032.615 </Td> </Tr> <Tr> <Td> Fiji </Td> <Td> 4,212 </Td> <Td> 8,200 </Td> <Td> 8,374 </Td> <Td> 9,353.390 </Td> </Tr> <Tr> <Td> Kiribati </Td> <Td> </Td> <Td> 1,700 </Td> <Td> 211 </Td> <Td> 1,820.750 </Td> </Tr> <Tr> <Td> Marshall Islands </Td> <Td> </Td> <Td> 3,300 </Td> <Td> 180 </Td> <Td> 3,239.708 </Td> </Tr> <Tr> <Td> Nauru </Td> <Td> </Td> <Td> 5,000 (2005 est .) </Td> <Td> - </Td> <Td> </Td> </Tr> <Tr> <Td> New Zealand </Td> <Td> 198,100 </Td> <Td> 35,200 </Td> <Td> 174,845 </Td> <Td> 37,108.005 </Td> </Tr> <Tr> <Td> Palau </Td> <Td> </Td> <Td> 16,300 </Td> <Td> 276 </Td> <Td> 15,260.417 </Td> </Tr> <Tr> <Td> Papua New Guinea </Td> <Td> 16,060 </Td> <Td> 2,400 </Td> <Td> 28,022 </Td> <Td> 3,542.097 </Td> </Tr> <Tr> <Td> Samoa </Td> <Td> 826 </Td> <Td> 5,200 </Td> <Td> 1,046 </Td> <Td> 5,368.510 </Td> </Tr> <Tr> <Td> Solomon Islands </Td> <Td> 1,155 </Td> <Td> 1,900 </Td> <Td> 1,198 </Td> <Td> 1,995.697 </Td> </Tr> <Tr> <Td> Tonga </Td> <Td> 454 </Td> <Td> 4,900 </Td> <Td> 557 </Td> <Td> 5,332.190 </Td> </Tr> <Tr> <Td> Tuvalu </Td> <Td> </Td> <Td> 3,300 </Td> <Td> 39 </Td> <Td> 3,566.816 </Td> </Tr> <Tr> <Td> Vanuatu </Td> <Td> 812 </Td> <Td> 3,300 </Td> <Td> 723 </Td> <Td> 2,631.360 </Td> </Tr> </Table> <Tr> <Th> Country </Th> <Th> Nominal GDP (2014 CIA estimate in millions USD) </Th> <Th> GDP per capita (2014 CIA estimate in USD) </Th> <Th> GDP (PPP) (IMF estimate in millions USD) </Th> <Th> GDP (PPP) per capita <P> (IMF estimate in USD) </P> </Th> </Tr>
