A billionaire, in countries that use the short scale number naming system, is a person with a net worth of at least one billion (1,000,000,000, i.e. a thousand million) units of a given currency, usually major currencies such as the United States dollar, the euro or the pound sterling. Additionally, a centibillionaire (or centi-billionaire) is commonly used to reference a billionaire worth one hundred billion dollars (100,000,000,000).[1][2] The American business magazine Forbes produces a complete global list of known U.S. dollar billionaires every year and updates an Internet version of this list in real time.[3] The American oil magnate John D. Rockefeller became the world's first confirmed U.S. dollar billionaire in 1916, and still holds the title of history's wealthiest individual.[4]

As of 2018, there are over 2,200 U.S. dollar billionaires worldwide, with a combined wealth of over US$9.1 trillion,[5] up from US$7.67 trillion in 2017.[6][7] According to a 2017 Oxfam report, the top eight richest billionaires own as much combined wealth as "half the human race".[8][9]

The United States has the largest number of billionaires of any country, with 536 as of 2015,[10] while China, India and Russia are home to 213, 90 and 88 billionaires respectively.[11][12] As of 2015, only 46 billionaires were under the age of 40,[10] while the list of American-only billionaires, as of 2010, had an average age of 66.[13]
