GDP by Country 2018
As of 2018, only four countries in the world have a GDP per capita in excess of US$100,000. These are Monaco (the highest at US$166,285), Liechtenstein, Luxembourg and Bermuda, all of which are known for attracting wealthy residents as well as for having very small populations, ranging from 38,155 (Liechtenstein) to 590,321 (Luxembourg). Conversely, at just US$247, South Sudan has the world's lowest GDP per capita, and many countries, predominantly in Africa, have a GDP per capita below US$1000.
Based on UN and IMF figures, the United States has the largest GDP in the world at US$20,412,870 trillion (IMF) and US$18,624,475 trillion (UN). The second-largest GDP is China's at $14,092,510 (IMF)/$11,218,281 (UN). However, the US has a population of 326,766,748, while China's population is the highest in the world – a massive 1,415,045,928 (although despite the significant difference, the US also has the third-highest population in the world, behind India in second place with 1,354,051,854).
Japan, Germany and the United Kingdom make up the rest of the top five countries with the largest GDPs at $5,167,050, $4,211,640 and $2,936,290 trillion (US$), respectively (based on IMF figures). Many island nations feature on the list of countries with the lowest GDPs. The British Commonwealth nation of Tuvalu is the lowest with a GDP of US$43 million, followed by the Micronesian island of Nauru at $114 million and the Marshall Islands at $205 million. Not surprisingly, these islands also have small populations and correspondingly low GDP per capita figures, ranging from $3,810 (Tuvalu) to $10,078 (Nauru).
